Recent Oracle Update [May 29, 2019]: You can track the status of long-running operations in the Compute service (like Create Instance, Custom Image,  Instance Pool, Updating & Deleting Instance Pool) using work requests.

This post covers:

• How to create a Compute Instance on Oracle Cloud (OCI).
• Viewing the State of a Compute Work Request
• Required IAM Policy
• Operations that Generate Work Requests
• Different Work Request States

Create a Compute (Linux/Windows) Instance in Oracle Cloud

1) Log in to the Oracle Cloud account.
Note: If you haven’t registered for the Oracle Cloud Free Trial account yet, then, please Download Step by Step Activity Guide to Register for Oracle Cloud Trial Account

2) Go to the Navigation Menu under Core Infrastructure, click Compute then Instance

3) Select the Compartment, in which you want to create the Compute machine

A compartment is a  logical container within your account used to store Oracle Cloud Infrastructure (OCI) Resources created within that compartment (such as compute, storage, and network) and you impose some policies to that compartment, which restricts who can use the resources created within than compartment other than administrators of your account.

By default, your instance launches in the current compartment, and the resources you choose also come from the current compartment.

To know more about the Compartment, check here

4) To create a Linux or Windows Machine, click on Create Instance. Fill up the required details

• When you click Change Image Source, the Browse All Images dialog box opens with the operating system or image source options (To create windows machine, select windows Image)
• Choose instance type: Select Virtual Machine or Bare Metal Machine.
• When you click Change Shape, the Browse All Shapes dialog box opens with a list of the virtual machine (VM) or bare metal shapes that are available for the instance type that you selected.

• Add SSH key: The public key portion of the key pair that you want to use for SSH access to the instance. You can drag and drop single key files into the box.

Note: SSH Keys are required only for Linux Machine and not for Windows Machine.

To know how to generate the SSH keys, please download the free Guide from here

Note: If you are new to Networking, & want to learn more about the Networking Basic Concepts like VCN, Subnet, Security List, IGW, DRG. Then please check here 

Once you click Create, you will see your Compute Linux Instance will start provisioning, & its status will change to Available in few minutes

After the instance is provisioned, details about it appear in the instance list. To view additional details, including IP addresses, click the instance name.

To know more about how to connect to the Compute Instance, check here

Viewing the State of a Compute Work Request

Many of the operations that you can perform in the Compute service do not take effect immediately.

For example, when you create an instance, it might take several minutes for the instance to transition from the provisioning state to running. When you launch a long-running operation, the Compute service spawns a work request.

A work request is an activity log that enables you to track each step in the operation’s progress. If an operation fails, a work request can help you determine which step of the process had an error.

• Work requests are retained for 12 hours.

Required IAM Policy

To use Oracle Cloud Infrastructure, you must be given the required type of access in a Policy written by an administrator, whether you’re using the Console or the REST API with an SDK, CLI, or other tools.

To enable users to list all work requests in a tenancy, use the following policy:

Allow group SupportTeam to inspect work-requests in tenancy

Operations that Generate Work Requests

These long-running operations spawn work requests:

• Creating an instance
• Creating a custom image
• Importing or exporting an image
• Creating an instance pool
• Updating an instance pool
• Deleting an instance pool

Different Types of Work Request States

The work request statuses are:

• ACCEPTED: The request is in the work request queue to be processed.
• IN_PROGRESS: A work request record exists for the specified request, but there is no associated WORK_COMPLETED record.
• SUCCEEDED: A work request record exists for this request and an associated WORK_COMPLETED record has the state SUCCEEDED.
• FAILED: A work request record exists for this request and an associated WORK_COMPLETED record has the state FAILED.
• CANCELING: The work request is in the process of canceling.
• CANCELED: The work request has been canceled.

This post discusses the Q/A & Review from the Day 2 of Oracle Apps DBA Training (R12.2) Install | Patch | Clone | Maintain Training Program. This will help you understand the concepts behind EBS Installation & Overview.

To check what we covered during the Day 1 of the Apps DBA Training Program, check my previous post [Q/A] Oracle Apps DBA Training (R12.2) Day 1: Architecture & Changes in Oracle E-Business R12.2.

In this session, we covered Module 2: R12.2 Staging & Installation which includes the following Topics:

The Apps DBA Training Program available on the Membership Portal looks like the screenshot below. We encourage the trainees to go through the well-done recorded videos before attending the Live session so they can come up with their doubts & clear them during the session to make it more Interactive.

R12.2 Installation Overview

Rapid Install is used to Install Oracle E-Business Suite (EBS) R12.2.

• Rapid Install uses the wizard which guides through the screens to install EBS both Express and Standard.
• Installation is done from the Staging Area (software downloaded and unzipped in a specific format).
• Check StartCD version before the Installation.

R12.2 Installation Phases

• Starting Installer
• Installation Phases
• Install Phase

Install Phase has two sub-categories:

• Database Tier Installation
• Application Tier Installation

To know more about the EBS R12.2 Installation check our post, Oracle Apps DBA (R12.2) Installation: FREE Training.

R12.2 Installation Related Q/A

Below are the R12.2 Installation related Questions asked during the Session:

Q.1. Is a fresh database installed without any data and vision having all the demo data?

Ans: Yes, if we choose a vision database while installing, we will get all the demo data.

Q.2. Can we continue a failed installation?

Ans: No, a failed installation in EBS 12.2 cannot be resumed. We have to restart the installation from the beginning in case it fails in the first place. However, if it fails within the precheck phase, you can retry the checkup phase.

Q.3. How much time does EBS 12.2 Installation take?

Ans: If you have a single core machine, it might take 6 to 8 hours for the installation to complete.

Q.4. Is there any utility for installation other than rapid install wizard?

Ans: No! EBS is the only utility used for installation in the rapid install wizard.

Port Pool Related Q/A

Next, we discussed the Port Pool, and given below is a short overview along with the Q/A.

A port pool is a preconfigured set of unique port assignments for every E-Business Suite technology stack component that requires network connectivity.

Port Pool is a set of default base value for each type of port. The value ranges from 0 to 99.

Q.5. Will changing the port pool impact the system performance?

Ans: Yes, changing the port pool can impact the system performance if the port conflicts with the high availability port. Port’s conflict with the high availability port might result in lower performance.

Q.6. How to check which is the run file system and which is the patch file system? 

Ans: By default, fs1 is the run file system and fs2 is the patch file system. However, after patching fs1 and fs2, the functionality is swapped in the cutover stage. To check what is what, we can check the environment variable FILE_EDITION.

Q.7. Can we have an admin server on multiple nodes?

Ans: No, Admin server is a singleton service and can run only on the primary node but will manage services on other nodes using the node manager.
Node Manager is a Java utility that runs as a separate process from WebLogic Server and allows you to perform the common operations tasks for a Managed Server, regardless of its location with respect to its Administration Server. While the use of Node Manager is optional, it provides valuable benefits if your WebLogic Server environment hosts applications with high availability requirements.
If you run the Node Manager on a machine that hosts Managed Servers, you can start and stop the Managed Servers remotely using the Administration Console or from the command line. Node Manager can also automatically restart a Managed Server after an unexpected failure.

Q.8. What is admin Console functionality?

Ans: The Administration Console is a Web Application hosted by the Administration Server. You access the Administration Console from any machine on the local network that can communicate with the Administration Server through a Web browser (including a browser running on the same machine as the Administration Server). The Administration Console allows you to manage a WebLogic Server domain containing multiple WebLogic Server instances, clusters, and applications.

The management capabilities include:

• Configuration
• Stopping and starting servers
• Monitoring server health and performance
• Monitoring application performance
• Viewing server logs

Assistants, which step you through the following tasks:

• Creating JDBC connection pools and DataSources
• Deploying your applications
• Configuring SSL

Through the Administration Console, system administrators can easily perform all the WebLogic Server management tasks without having to learn the JMX API or the underlying management architecture. The Administration Server persists changes to attributes in the config.xml file for the domain you are managing.

This blog post comes with the third video of the Multi-Part Video Series on “Oracle Exadata Cloud Service for DBAs & Apps DBAs”. In this post, I’ll be discussing the Deployment Options available for Exadata i.e. Cloud Service (ExaCS), Cloud at Customer (ExaCC) and Exadata Machine.

(To be the first one to receive Updates on Oracle Exadata Database, On-premise and On-Cloud, Subscribe to Our Newsletters.)

Deployment Options

There are three deployment options available for Exadata:

1. Exadata Cloud Service (ExaCS)
2. Exadata Cloud at Customer (ExaCC)
3. Exadata Machine

Let’s see the difference between these deployment options in brief.

• Exadata Management. In the traditional On-Premise Exadata, Exadata Database Machine is in the client’s datacentre and is the client’s responsibility to manage the Exadata hardware with Oracle. However, in ExaCS and ExaCC, Oracle manages the Exadata hardware and firmware and the client manages the Exadata operating system and the database.
• Data. In On-Premise Exadata Machine and ExaCC, the Exadata runs within the client’s datacentre but in ExaCS, Exadata is deployed on Oracle’s Public Cloud in one of the available regions such as US, Japan, South Korea, UK, Germany, etc i.e. in ExaCS, data doesn’t stay in the datacentre of the client.

Note: The client can restrict the data to a specific region in ExaCS. 

• Services. No Cloud services are offered for On-Premise Exadata Machine. However, in ExaCC and ExaCS, Oracle provides the client with Cloud services such as Cloud Control Plane, Advanced Support Gateway, Oracle Object Storage instance, Cloud Tools, etc. Additionally, in ExaCC, Oracle Advanced Support Gateway service is provided.
• Model. In On-premise, the Exadata Database Machine is provided on the purchased-based but in ExaCC and ExaCS, Exadata is used as a service and are provided on the subscription-based model by Oracle.

Note: One can purchase a Compute Machine On-premise to create other machines, to deploy other Cloud instances like Java Service Cloud or SOA Cloud Service or Compute.

Why Is Cloud Control Plane Important?

Cloud Control Plane is a Cloud software which manages billing, identity, REST services, compute, storage, etc. Cloud Control Plane also manages other Cloud services running on the datacentre. 

Note: Only one Control Plane is required for each datacentre, irrespective of the number of the Cloud Instances.

What Is The Role Of Oracle Advanced Support Gateway in ExaCC?

Architecture of ExaCC

The Oracle Advanced Support Gateway is used to send Exadata monitoring data to Oracle Support Team. In return, Oracle Support Team remotely manage Exadata Hardware, Patching Firmware, Infiniband Network via VPN to ensure the proper functioning of Exadata.

Why Should A Client Choose ExaCC Over ExaCS?

Here are a few reasons why the client should pick ExaCC over ExaCS:

• Data Residency Law. ExaCC follows the Data Residency Law in which the data remains only at the datacentre of the server.
• Security. Since the data resides in the datacentre, there is no risk of a security breach. The data is relatively more secure in an ExaCC.
• Complication. Clients may find it difficult to lift and shift to the Cloud. But in ExaCC, the client doesn’t have to shift their complicated systems to the Cloud. They can avail the Cloud services at their own datacentres.

Services offered in ExaCC

This post is the First video of a Multi-Part Video Series on “Oracle Autonomous Database Cloud for DBAs & APPS DBAs“.

I”ll be covering Overview of Autonomous Database, Types of Autonomous database (Autonomous data warehouse & Autonomous Transaction Processing) and Autonomous offering as Serverless & Dedicated Infrastructure.

(To be the first to receive Updates on Oracle Autonomous Database Cloud [1Z0-931], Subscribe to Our Newsletters.)

What is Autonomous Database

Oracle Autonomous Database is a combination of Exadata with database and infrastructure automation running on Oracle Gen 2 Cloud i.e Oracle Cloud Infrastructure (OCI).

It is a cloud database that uses machine learning to eliminate the human labor associated with database tuning, security, backups, updates, and other routine management tasks traditionally performed by database administrators (DBAs). It is self-driving, self-securing, self-repairing database service. 

Types of Autonomous Database

When you configure the database system on the basis of workload, Oracle Autonomous Database is categorized into two types as Autonomous Data Warehouse (ADW) and Autonomous Transaction Processing (ATP)

1. Autonomous Data warehouse (ADW)

Autonomous Data Warehouse is a fully managed database tuned and optimized for data warehouse workloads with the market-leading performance of Oracle Database. It is Easy, Fast and Elastic scaling of compute and storage, without downtime.

Autonomous Data Warehouse uses the same Oracle Database software and technology that runs your existing on-premises workloads.

For more details information on Autonomous Data warehouse (ADW) click here 

2. Autonomous Transaction Processing (ATP)

The Autonomous Transaction Processing (ATP) workload type configures the database for a transactional workload, with a bias towards high volumes of random data access. Eg Transactions, Batch, Reporting, Machine Learning etc.

Autonomous Deployment options:

Oracle Autonomous Database offers two deployment options Serverless or  Dedicated.

1. Serverless Oracle Autonomous DB is Ultra-Simple and Elastic. In Serverless you don’t know where is the Exadata server present this means you dont own the infrastructure.

With this option, you simply select what type of database you want (Data Warehouse or Transaction Processing), which region in the Oracle Cloud you want the database deployed, and the base compute and storage resources and then Oracle automatically takes care of everything for you.

2. Autonomous Database Dedicated is Customizable Private Cloud in Public Cloud. You can customize the software update/patching policy etc.

With Autonomous Database Dedicated, you get your own Exadata infrastructure in the Oracle Cloud also you can simply specify the size, region and availability domain where you want your dedicated Exadata infrastructure provisioned.

Stay tuned for my next blog in which I’ll be covering Autonomous Database for WHO & WHY?

This post is the fourth in a Multi-Part Video Series on “Oracle Exadata Cloud Service for DBAs & APPS DBAs“. In this post, I’ll be discussing the Exadata Cloud Service (ExaCS) Offerings which are Quarter Rack, Half Rack and Full Rack shapes of Exadata and X6, X7 models of Exadata.

(To be the first to receive Updates on Oracle Exadata Database, On-premise and On-Cloud, Subscribe to Our Newsletters)

Shape of Exadata Cloud Service

The hardware of the Exadata that the client chooses refers to the shape of ExaCS. Oracle ExaCS is available in four shapes:

1. Quarter Rack
2. Half Rack
3. Full Rack
4. Base

Quarter Rack

Oracle Exadata Quarter Rack consists of 2 Database Servers and 3 Storage Servers. It contains up to 92 CPUs in all the Database Servers combined with RAM up to 1440 GB. The Flash Raw Storage and Usable Disk Storage are up to 76.8 TB and 106.9 TB respectively.

Note: The configuration of CPUs, memory and storage depends on the model i.e X6 and X7.

Half Rack

Oracle Exadata Half Rack consists of 4 Database Servers and 6 Storage Servers. It contains up to 184 CPUs with RAM up to 2880 GB. The Flash Raw Storage and Usable Disk Storage are up to 153.6 TB and 213.8 TB respectively.

Full Rack

Oracle Exadata Full Rack consists of 8 Database Servers and 12 Storage Servers. It contains up to 368 CPUs with RAM up to 1440 GB. The Flash Raw Storage and Usable Disk Storage are up to 307.2 TB and 427.6 TB respectively.

Base

The newly launched Oracle Exadata Base is similar to Quarter Rack configuration as it contains 2 Database Servers and 3 Storage Servers. However, there are less number of CPUs available. The Base can contain up to 48 CPUs and has a lower configuration of memory and storage as compared to Quarter Rack. (Consider it equivalent to 1/8th of a Full Rack)

Note: One cannot switch from one shape to another, directly. Although migration options such as Data Guard and Backup & Restore can be used to switch the shape of the Exadata.

Models of Exadata

There are two most common hardware machines or models of Oracle ExaCS, as of June 2019, are:

1. X6
2. X7

X6

For Exadata On-Cloud, Exadata X6 machine is available for all configurations with the following specifications:

X7

X7 is the latest version of Exadata available for Exadata Cloud. It offers much higher memory and storage capacity in comparison to X6.

Note: In June 2019, Oracle launched the Exadata X8 machine for Exadata On-Premise and the same shall soon be available for Exadata On-Cloud as well.

The post [Video] Oracle Exadata Cloud Service(ExaCS) Offerings appeared first on Oracle Trainings.

This blog post comes with a high-level overview of the options available to migrate Database from On-Premise to Autonomous Database Cloud.

If you are new to Oracle Autonomous Database, it is the database on Cloud to automatically patch, upgrade and tune itself. For an overview, Two Types (ADW, ATP) and Two deployment options (Serverless and Dedicated), check HERE.

First, let’s talk about the different options available to load the data.

Data Loading Options:

When you migrate the Database to the Autonomous Database, there are two options available to load data:

1. From On-Premise: You can directly load your data from your On-premise server to the Autonomous Database.
2. From Object Storage Cloud: You can also load your data to Cloud Object Storage first, and then migrate to the Autonomous Database from Object Storage Cloud. This is a fast process for Database Migration.

Different Methods to Migrate to Autonomous Database Cloud:

Now coming to the different methods available to migrate the Database from On-Premise to Autonomous Database Cloud, there are mainly four Migration methods:

1. Using DBMS_CLOUD package
2. Using Data Pump
3. Using SQL Loader
4. Using Oracle GoldenGate

1. Using DBMS_CLOUD:

The package DBMS_CLOUD supports loading from files in the following Cloud Services: Oracle Cloud Infrastructure Object Storage, Oracle Cloud Infrastructure Object Storage Classic, Azure Blob Storage, and Amazon S3. For data loading from files in the Cloud, you need to store your object storage credentials in your Autonomous Data Warehouse first, and then use the DBMS_CLOUD.COPY_DATA procedure to load the data.

Below is the High-Level Migration Process using the DBMS_CLOUD:

• Copy all the data file(s) to Object Storage on Cloud.
• Store your Object Storage credentials in your Autonomous Database (ADB).
• Copy the data file into an existing table using:
  DBMS_CLOUD.COPY_DATA
• Check the status of the operation.

2. Using Data Pump:

Oracle Data Pump provides very fast bulk data movement between Oracle Databases and Autonomous Data Warehouse. Using this method, you can import data from Data Pump files kept on Oracle Cloud Infrastructure Object Storage, Microsoft Azure, AWS S3, and Oracle Cloud Infrastructure Object Storage Classic. You can save your data to your Cloud Object Store and use the Oracle Data Pump to load data to the Autonomous Data Warehouse.

Below is the High-Level Migration Process using the Data Pump:

• Export data in the Schema Mode.
• Copy the dump file(s) to object Storage on Cloud.
• Store your Object Storage credentials in ADB.
• Import using the impdp method.
• Check the Logfiles for any issue.

3. Using SQL Loader:

You can use Oracle SQL Loader to load data from local files in your machine to Oracle Autonomous Data Warehouse. Using SQL Loader is suitable for loading small amounts of data as the load performance depends on the network bandwidth between your client and the Autonomous Data Warehouse.

Below is the High-Level Migration Process using the SQL Loader:

• Configure the connection wallet & variables.
• Gather one or more data files.
• Create a control file (optional).
• Create a table in destination DB.
• Load using the SQL Loader.
• Check Log, Bad, and Discard files.

4. Using Oracle GoldenGate:

You can also use GoldenGate to replicate data to Autonomous Data Warehouse using the Oracle GoldenGate On-Premises and Oracle GoldenGate Cloud Service. Make sure you use the Oracle GoldenGate On-Premises releases 12.3.0.1.2 and later as a source as only these versions are certified with Oracle Autonomous Data Warehouse Cloud. Other Sources could be Oracle Database Cloud Service or Oracle Exadata Cloud Service on Oracle Cloud. However, you can’t set up the Oracle Autonomous Data Warehouse Cloud Database as a source Database for Oracle GoldenGate On-Premises and only non-integrated Replicats are supported with Oracle Autonomous Data Warehouse Cloud.

Below is the High-Level Migration Process using Oracle GoldenGate:

• Configure the Autonomous Database for Replication by creating the required schema, target tables, new target user, etc.
• Obtain the Autonomous Database client credentials. 
• Configure Oracle GoldenGate On-Premises for replication by transferring the client credentials zip file, configuring sqlnet.ora, and tnsnames.ora, etc.
• Configure Oracle GoldenGate Manager and non-integrated Replicats to deliver to the Autonomous Database.

This is all about Migration to Autonomous Database and methods available for the same in nutshell.

No protocol specified
X-Server access is denied on host
(Fatal Error] DISPLAY variable set incorrectly: :O.0
[Resolutionj Verify that your DISPLAY environment variable is set correctly,
and that there is an Xli server on the system. If you are
running the Oracle Installer as a different user or on a different host,
you may need to use the xhost command to ensure that host/user
has permission to write to your display.

Root Cause:

When you run the installation from a remote terminal, or if you use a su command to change users you might receive an error.

This Error occurs if the Display variable is not set, or the user running the installation is not authorized to open an X window.

If you starting your Host or server with Root user and use su command to change from a user with lower-privileged user, such as (Oracle) that is authorized to run the Fusion infra installer but not authorized to open an X window on the display, you will hit this error as X-server Access is denied on Host. 

Troubleshooting:

To troubleshoot this issue, run the command echo $DISPLAY to ensure that the display variable is set to the correct host. If the display variable is set correctly then either ensure that you are logged in as the user authorized to open an X window, or run the command xhost + to allow any user to open an X window.

Step By Step Instructions to Fix Issue

Step 1: Make sure you are login to root user and run the command echo $DISPLAY to ensure that the display variable is set to the correct host.

                 # echo $DISPLAY

                     :0.0

Step 2: With Root user, run the command xhost + to allow any user to open an X window

Oracle Integration Cloud (OIC) provides a large set of connectors/adapters to connect to Oracle’s SaaS and on-premise applications in addition to many third-party Cloud and on-prem applications. Some of these adapters/connectors use a connectivity agent to establish a connection with the on-premise system while a connectivity agent uses the JVM (Java Virtual Machine) to run code on the on-premise system.

This blog post discusses the steps to Download and Install JDK Version 8 on Windows and setting the Environment variables. At this point of time, Oracle has provided documents saying the connectivity agent requires Java to be installed on the on-premise system and it only supports Java version 8 and 9 for the connectivity Agents.

If you are new to Oracle Integration Cloud (OIC), then check our previous blog post at Oracle Integration Cloud (OIC) For Beginners Overview.

Step 1: Download Java JDK 8

1. You need to download Java 8 from the Oracle’s Official Java Website. Open Java is not supported by Oracle Connectivity Agents.

2. You will see two options, 32-Bit and 64-Bit versions to download. You can choose either of them based on your system.

3. Go ahead, accept the license agreement and download the file.

Step 2: Run the Installer

1. Install Java by opening the location of the downloaded executable.

2. Double-click on it to run the installer.

3. On Windows 10, a pop-up window will appear. Click on the “Install anyway” option.

4. The JDK installer will start. Click on “Next”.

5. The JDK installation will start now. A progress bar shows the various steps being executed.

6. Once the installation is complete, click on “Close”.

Step 3: Set JAVA_HOME Variable and Path Variable for JDK8 on Windows 10

1. Set up an environment variable that will point to the JDK installation.

2. Go to the “Edit environment variables for your account”.

3. Click on “New”.

4. Enter “JAVA_HOME” as the variable name and [JAVA_INSTALL_DIR] as the variable value. For us, the Java installation directory is C:\Program Files\Java\jdk1.8.0_191.

Click on “OK”.

5. Configure the PATH environment variable so we can run Java from the command prompt. Select the Path variable and then click on “Edit”.

6. Click on “New” and type “%JAVA_HOME%\bin” as shown in the screenshot below. Click on “OK”.

7. Click on “OK” to close the environment variables window.

Step 4: Check the version of Java installed

1. Open the Command Prompt.

2. Type “java -version” and press the ENTER key on your keyboard.

Now, Java has been successfully installed on the system and you can go ahead with Connectivity agent installation at on-premise.

This post is the fifth in a Multi-Part Video Series on “Oracle Exadata Cloud Service for DBAs & APPS DBAs”. In this post, I’ll be discussing the Exadata Cloud Service (ExaCS) Storage Options which are Flash Storage and 3 ASM Disk Groups namely Data, Reco and Sparse Storage.

(To be the first to receive updates on Oracle Exadata Database, On-premise and On-Cloud, Subscribe to Our Newsletters)

Storage Options in ExaCS

Depending on the configuration, there are 3, 6 and 12 Storage Servers in Exadata Cloud Service. In each Storage Server, there are four types of storage:

• Flash Storage
• 3 ASM Disk Groups: Data, Reco and Sparse

Flash Storage

Exadata’s Flash Storage has a special feature called Smart Flash Cache. All the frequently accessed data files are stored here.

ASM Disk Groups

Automatic Storage Management or ASM disk groups is Oracle’s storage management unit. It has 3 disk groups and all of them have high redundancy. These disk groups are:

1. Data Disk Group
2. Reco Disk Group
3. Sparse Disk Group

Data Disk Group

In the Data Disk Group, all the less frequently accessed data and other data files are stored.

Reco Disk Group

Reco or Recovery Disk Group is known for Fast Recovery Area (FRA) i.e. it is used for backup and recovery. All the backup files like RMAN backup and Archive Redo logs are stored here.

Sparse Disk Group

Sparse Disk Group is an optional disk group. Unlike other disk groups, the client can choose whether they wish to create it or not.  This disk group is used to store the snapshots of the Exadata Server, which are quick and memory-efficient clones of Exadata Database Server and are easy to create and destroy. These snapshots are mainly used in Development and Testing environment.

Note: The creation of Sparse Disk Group is advisable.

Other Options While Provisioning Exadata

Normally, Exadata gives 60%  and 40% of the usable disk storage to Data Disk and Reco Disk, respectively. However, these can vary when we customize our Exadata Database. There are two options available while creating an Exadata Database:

1. Create Sparse Disk Group
2. Database Backup on Exadata Storage

Choosing any of these or both of these options changes the percentage of memory allocation of each storage type in the following manner

Note: The actual usable disk space is less than what is provisioned.

OIC provides a large set of connectors/adapters to connect to Oracle’s SaaS and on-prem applications and many third-party cloud and on-prem applications.

Oracle ERP Cloud Adapter is used to connect to Oracle Cloud ERP. Oracle Cloud ERP offers the most complete and integrated Enterprise Resource Management solutions for operations, GRC and performance management.

In this post, I am going to give you an overview of what is ERP, ERP Cloud Adapter and how to use OIC to integrate with ERP with High-Level Steps for importing the data into ERP Cloud using OIC.

If you are new to Oracle Integration Cloud (OIC), then check out our blogs on Oracle Integration Cloud (OIC) For Beginners Overview.

What is ERP Cloud?

“ERP” stands for enterprise resource planning. It refers to a suite of software that organizations use to manage day-to-day business activities, such as accounting, procurement, project management, risk management and compliance, and supply chain operations. A complete ERP suite also includes enterprise performance management, software that helps to plan, budget, predict, and report on an organization’s financial results.

ERP systems tie together and define a plethora of business processes and enable the flow of data between them. By collecting an organization’s shared transactional data from multiple sources, ERP systems eliminate data duplication and provide data integrity with a “single source of truth.”

Features of Orale Integration Cloud (OIC)

1. Oracle Integration Cloud (OIC) can be leveraged to import data from external feeds (published in SFTP) to Oracle ERP Cloud.
2. OIC simplifies how you build integrations in the cloud, letting you connect securely to applications and services both in the cloud and on-premises.
3. OIC exposes a browser-based user interface through which the integration is first designed, then activated and managed.
4. It also provides connectors/adapters to easily interact with a number of popular SaaS applications. One such connector that OIC provides is the Oracle ERP Cloud Adapter which is used to connect to Oracle Cloud ERP.

Solution Design

The diagram below describes the entire flow involving the various steps while importing
the data into ERP Cloud using OIC

The entire solution is divided into 3 steps. Each of these steps has an OIC flow associated. The solution design is shown below:

High-Level Steps for importing the data into ERP Cloud using OIC.

Step 1: Generate FBDI File

The first step is to generate a File-Based Data Import (FBDI) file for ERP’s consumption. Most of the bulk integration with ERP is through FBDI File.

The source application’s data file may not be in the FBDI format always. In this case the source application data format needs to be converted to FBDI format. This can be achieved by applying cross-references master data values from Oracle ERP cloud in a custom layer by either making the changes in the source system to burst out the data in FBDI template or by using procedures in a database layer and applying the transformation to get FBDI formatted files.

7 Steps to generate the FBDI format.

1. Read Trigger File: This is scheduled OIC integration that gets triggered based on a scheduled configured. The first step is to read the trigger file that will be put in FTP location.
2. Download Source Data File: downloading the source data file into OIC because chunking of the file on FTP Server is an expensive operation.
3. Chunk Read and Transform to FBDI: Stage Read feature in OIC to chunk read file. Then every chunk is transformed from source format to FBDI format and then output FBDI file is written.
4. List File: List file is needed for OIC to determine how many FBDI files are written out.
5. Generate Property File and Write zip file: OIC uses ERP Adapter to upload FBDI file to ERP. Although the ERP Adapter makes uses of ERP provided web services internally, it obfuscates many complexities involved in the raw ERP web services.
6. Archive Source File: The source file is archived for the future on an FTP location for re-submission purposes if necessary in the future.
7. Archive Trigger File: The trigger file is archived for the future on an FTP location for re-submission purposes if necessary in the future.

Step 2: Upload to ERP

The second step is to consume the FBDI file generated in Step 1 and upload the file to ERP.

ERP exposes web services (mainly SOAP) to upload data to ERP. While these services can be made use directly using a SOAP call, there are some complexities involved in terms of dealing with a binary file like zip file to upload data and receive data.

Retrieving and uploading the zip files using a simple SOAP call maybe little cumbersome. Fortunately, OIC has an ERP Adapter that abstracts several of these complexities. So, for all the cases, the ERP Adapter is used.

Step 3: Receive Callback from ERP

In this OIC flow, a callback from ERP is received. It is possible to receive a callback on SUCCESS, ERROR or BOTH.

Receive Callback from ERP

The flow is triggered when ERP asynchronously calls back OIC. The callback was configured when the ERP adapter is configured to invoke.

Write Result File

The callback from ERP contains a zip file that has all the results of the jobs that ran on the ERP. This can be written out on to a FTP location.

Summary

• OIC orchestration pattern helps us in designing complex integration scenarios.
• ERP Adapter helps to integrate with Oracle ERP Cloud.
• ERP Adapter provides encapsulation especially dealing with batch integration using FBDI.
• OIC is the prefered service when it comes to integrating between SaaS and SaaS or On-prem and SaaS. OIC offers the depth of integration capabilities dealing with Oracle SaaS.

The post Oracle Exadata Cloud Service (ExaCS) Training: Step-By-Step Activity Guides/Hands-On Lab Exercise appeared first on Oracle Trainings.

This post discusses the Troubleshooting Steps for Connectivity Issues you can face while connecting to a Compute/Database Instance in Oracle Cloud (OCI).

Let’s start with the pre-checks you should follow before connecting to the Compute/Database Instance.

PRE-CHECKS:

• The Instance should be created in the Public Subnet.
• Subnet should have a Route to the Internet Gateway.
• Port 22 (Linux)/3389 (Windows) should be Open in the Security List.
• Use the correct SSH Private Keys.
• If connected to the office VPN/network, Port 22/3389 should be open.

Check 1: Subnet Should be Public.

Note: To connect to your Instance, you’ll need its public IP address. You will get the public IP only when you have used the Public Subnet while creating the Instance. If you have selected the Private Subnet, you can’t change it to the public and you will have to create a new Instance in the Public Subnet. 

Steps to Get the Public IP of the Compute Instance:

1. In the Console, click on “Compute”. 
2. Click on the Instance name to see its details. 

3. Make a note of the Public IP Address. 

Steps to Get the Public IP of the Database Instance:

Note: You will get the public IP only if you have used the Public Subnet. If you have selected the Private Subnet, you can’t change it to the public, and you will have to create a new Instance.

1. Login to the OCI Console and navigate to the Database section.

2. Click on the Database name on which you want to connect.

3. On the left side of the Database Instance Details page, click on Nodes under the Resources.

Check 2: Route to the Internet Gateway (IGW).

Next Step is to check the Public Subnet belonging to the Instance should have a Routing Table going to the Internet Gateway.

1. Login to the OCI console, navigate to the VCN & select the VCN which you have used during Instance creation.
2. Go to the VCN details page, & click on the Public Subnet which belongs to the Instance.

3. This Subnet should have the Route Table associated with it and that Route Table should have a connection to the Internet Gateway.

If you created the VCN without Related Resources, then you have to manually create the Internet Gateway & the Route Table.

Steps to Create Internet Gateway & Add Route Rule: 

1. Click on the VCN, then under Resources click on the Internet Gateway.
2. Create an Internet Gateway and fill all the required details.

3. Click on the Route Table from the left Submenu.
4. Click on the Default Route Table and add the Route Rules.
5. Enter the required fields (Target type, Destination CIDR Block, Compartment, Target IGW).

Check 3: Port 22 (Linux)/3389 (Windows) Should be Open.

Next step is to check if Port 22 (Linux) & 3389 (for Windows) is opened in the Security List.

Note: Security List is the firewall which allows the connection.

1. Under Networking, click on VCN.
2. From the left submenu, select the Public Subnet in which you have created the Database or the Compute machine.
3. Click on the Security List and then click on the Security List name.
4. Under your Security List, add an Ingress rule to open Port 22 (for Linux) & open Port 3389 (for Windows).

Note: If you want to open port 1521, then follow the same process & you can give the source CIDR of your choice, where 0.0.0.0/0 will open for the Public Internet & in the same way you can provide the VCN or Subnet CIDR.

Check 4: Use the Correct SSH Private Keys.

When you try to connect via Putty, it prompts for the Username and afterward shows the “Disconnected No Supported Authentication methods required” error message as shown below. It means there is some issue with the keys you provided.

PUTTY Fatal Error: Disconnected: No supported authentication methods available (server sent: publickey, gssapi-keyex, gssapi-with-mic)

FIX:

If you are getting the above-mentioned issue, it means the Public Key you have added to your Instance is wrong.

Try to create a new Instance & add the new Public Key again. 

Or

Check if you have added the Private key under SSH->Auth or not.

Steps for Connecting to a Database/Compute Instance: 

There are 3 main ways to network to Oracle Cloud Instance i.e…

1. SSH (Secure Shell)
2. IPsec VPN (Virtual Private Network)
3. FastConnect

Note: Here is a slide from the Connectivity/Security Module of our Cloud Training

Now that you have performed all the Steps for troubleshooting, check whether you can connect to your instance or not.

You can connect to a running Instance using a Secure Shell (SSH) for Linux or Remote Desktop connection for Windows. To connect to a Linux Instance from your Laptop, you can download a FREE SSH client called PuTTY from Here. 

Enter the Public IP Address in the Hostname, then add the SSH Private key under SSH & then Auth. Click on Open.

Well, that was all on How to Create & Connect Windows/Linux machine on Oracle Cloud (OCI).

Hope the mentioned troubleshooting steps will help you.

The post Oracle Cloud for DBAs: 8 Things Every Beginner Should Know appeared first on Oracle Trainings.

This post covers the sixth video of my Multi-Part Video Series on “Oracle Exadata Cloud Service for DBAs & APPS DBAs”. In this post, I’ll be discussing the Networking of Exadata Cloud Service (ExaCS) focusing on IPs, VCN and Subnets.

(Be the first one to receive updates on Oracle Exadata Database, On-Premise & On-Cloud, Subscribe to Our Newsletters)

In order to provision an instance of Exadata On-Cloud, one needs to create a Virtual Cloud Network (VCN) and two Subnets.

Virtual Cloud Network (VCN)

While creating an instance of Exadata On-Cloud one should create a VCN first. A VCN is a contiguous block of IP addresses, represented in a CIDR format. These IP addresses make up the network.

While creating a VCN there are two options available:

1. Create VCN only
2. Create VCN with related resources i.e. VCN with Subnets, Route Table, Subnets, Security Lists, etc.

Note: It is suggested we choose Create VCN only and create other resources manually.

Note: Learn how to create VCN, Subnets, Internet Gateway, Security List & Dynamic Routing Gateway on Oracle Cloud.

Subnets

A VCN can further be divided into smaller parts called Subnets. For an Exadata on-Cloud, there are two subnets that are required:

• Client Subnet
• Backup Subnet

Note: It is advisable to Create Regional Subnets

Client Subnet

A client subnet can either be public or private. All the clients connect to Exadata on-Cloud using the IP addresses assigned in this subnet.

Backup Subnet

A backup subnet is a private. While creating a backup of the database, it uses the IP addresses assigned in this subnet.

The Requirement of IP Addresses

We can choose the number of IP addresses we require in each subnet, depending on the configuration of the system. For client subnet, a minimum of 2 IP addresses per node with 3 SCAN IP addresses is required for the functioning of the rack.  And for the backup subnet, a minimum of 1 IP address for each node of the rack is required. Additionally, 3 reserve IP addresses are required for both client and backup subnet.

The post [Video] Oracle Exadata Cloud Service (ExaCS) Networking appeared first on Oracle Trainings.

One of the important tasks of a Cloud Administrator/Cloud Architect is to check & track the usage and billing of the Cloud resources they use for their day-to-day business goals.

This blog post, in a detailed manner, discusses how to get the usage reports in Oracle Cloud Infrastructure (OCI) using the Cloud Console.

What is Usage Reports in OCI?

A usage report is a breakdown of the consumptions of your Oracle Cloud Infrastructure resources such as the compute, networking, storage, etc where you get a report in the CSV format for audit or an invoice reconciliation task.

Why is it Required?

Analyzing your Cloud Bill

• If you want to get a granular view of spending or find the ways to save, you need detailed information about your Oracle Cloud Infrastructure consumption. Usage reports enable you to gain more insight regarding your bill or create custom billing applications.
• The reports contain one record per resource (for example, an Instance, a DB system, or an Object Storage Bucket) per hour with metadata and tags.
• In addition to enabling the new billing scenarios, usage reports also provide transparency into how the billing system works. For example, you can now see how and where the rounding occurs, and how the resources that existed for less than an hour are billed.
• You can download the usage reports through the web-based console or by using APIs.

Optimizing your Cloud Usage

• You can manage your Cloud credits by analyzing the cost and optimizing the use of the Cloud resource to a certain bound.

How does it work?

• The usage report is automatically generated daily and is stored in an Oracle-owned Object Storage Bucket.
• It contains one row per each Oracle Cloud Infrastructure resource (such as for an Instance, Object Storage Bucket, VNIC) per hour along with the consumption information, metadata, and tags.
• A usage report generally contains the 24 hours of data usage although occasionally a usage report may contain the late-arriving data that is older than 24 hours.
• The usage reports are retained for a year.

Steps to Get the Usage Reports In OCI

1. Open the navigation menu, and under “Governance and Administration”, go to the “Billing and Usage Report”.

2. Click on the “Usage Report” and copy the policies for configuring the Usage Report.

Note: This is a one-time operation & after that, you will get all your usage reports under the “Usage Report” section.

3. Once you have copied both the policies mentioned in the second step, now you need to create a new policy and then define the policy which you have copied from the “Usage Reports” section.

Note: We will use the “Administrator” group for defining the second policy.

Open the navigation menu, under “Governance and Administration”, go to “Identity” and select “Policies”.

Note: Make sure you write both the policies at the same time.

4. Once you have successfully created the policy, go back to the “Usage Reports” section and all your usage reports will start reflecting. Now, you will be able to download your usage reports.

Hope you find this blog post useful in understanding the usage reports in Oracle Cloud Infrastructure.

If you hit any issues while creating or accessing the usage reports in Oracle Cloud Infrastructure, please post in the comment section & stay tuned for my upcoming blog posts where I will be sharing some Oracle Cloud Infrastructure (OCI) related useful content.

The post How To Get The Usage Reports In Oracle Cloud Infrastructure appeared first on Oracle Trainings.

This post covers an issue that one of our trainees from Oracle AppsDBA (R12.2): Install | Patch | Clone | Maintain training (For FREE Master Class, Click here) was facing while applying the patch 27254132 & also includes the fixes of the Issue.

If you are new to Oracle E-Business Suite, then I would suggest you check our previous post where we have covered in detail about  Oracle AppsDBA (R12.2)Architecture. & Oracle AppsDBA (R12.2) Installation: Free Training

Before looking on to the issue let us discuss the overview of ADOP

ADOP Overview

ADOP stands for Application DBA Online Patching,  introduced in EBS R12.2 to patching Oracle Applications while the system is available for users during Patching.

In an Online Patching, there are five phases PREPARE -> APPLY -> FINALIZE -> CUTOVER  -> CLEANUP

ADOP uses a dual file system (a feature introduced in R12.2) to support online patching.

1. adop phase=prepare -> copies the application code
2. adop phase=apply -> apply patches to PATCH Environment
3. adop phase=finalize -> makes ready the system for cutover
4. adop phase=cutover -> bounce the system and does filesystem switchover. fs2 becomes RUN environment.
5. adop phase=cleanup -> remove obsolete objects.
6. adop phase=fs_clone -> synchronize filesystems

Note: that after cutover the command line environment should be re-loaded as the run edition file system has changed.

In a multi-node deployment, ADOP commands are only executed from the Primary Node. The primary ADOP session uses remote execution to automatically perform the required actions on any secondary node.

What Is Hotpatch?

Online patching has been introduced in EBS 12.2. So An EBS 12.2 patch is normally applied using an ADOP online patching cycle, which is the only case tested internally before 12.2 patches are released (unless documented otherwise).

We can use Hotpatch mode only for certain patches, such as NLS and Online Help, or when it is specifically documented in the patch readme. In EBS release 12.2, certain kinds of patches are even less stable for use with “hotpatch” than they were in EBS 12.1!

In this post, I have discussed how to get the Public IP of Database in Oracle Gen 2 Cloud & Connect to the Database Instance using PUTTY.

As per the latest update [July 2019] in the Oracle Cloud Database console, the navigation of getting the public IP has been changed.

We are getting lots of requests from our trainees, as they are unable to get the Public IP of the Database, so I thought of creating a blog post for the same.

Database Offerings

In Oracle Cloud Infrastructure, Database is divided into two types:

• User-Managed Database
• Autonomous Database

Note: To know more on how to get the Database On Oracle Cloud (OCI): User-Managed and Autonomous Database, Check here

Steps to Get the Public IP of the Database Instance

Note: You will get the public IP only if you have used the Public Subnet. If you have selected the Private Subnet, you can’t change it to the public, and you will have to create a new Instance.

1. Login to the OCI Console and navigate to the Database section.

2. Click on the Database name on which you want to connect.

3. On the left side of the Database Instance Details page, click on Nodes under the Resources.

Steps for Connecting to a Database Instance: 

There are 3 main ways to network to Oracle Cloud Instance i.e…

1. SSH (Secure Shell)
2. IPsec VPN (Virtual Private Network)
3. FastConnect

Note: Here is a slide from the Connectivity/Security Module of our Cloud Training

Now that you have performed all the Steps for troubleshooting, check whether you can connect to your instance or not.

You can connect to a running Instance using a Secure Shell (SSH) for Linux or Remote Desktop connection for Windows. To connect to a Linux Instance from your Laptop, you can download a FREE SSH client called PuTTY from Here. 

Enter the Public IP Address in the Hostname, then add the SSH Private key under SSH & then Auth. Click on Open.

Well, that was all on How to Create & Connect Windows/Linux machine on Oracle Cloud (OCI).

Hope the above-mentioned steps will help you.

The post [AZ-900] Microsoft Azure Certification Fundamental Exam: Everything You Must Know appeared first on Oracle Trainings.

[Update: 12th Aug’19] OCI Resources now can move across compartments and compartment itself can move to.

Compartment is the first thing you will select when creating any OCI resource like Compute, Storage, Network/VCN, Load Balancer, Database etc so it is very important to understand compartment in OCI.

This post covers everything you must know about Compartment.

• Overview of Compartment
• Quick facts about Compartment
• How to Create a Compartment in OCI
• How to Grant Access in Compartments
• Creating Resources in a Compartment
• Moving Resources to a different Compartment
• Moving Compartment and its implications
• Delete a Compartment in OCI
• Renaming a Compartment
• Viewing a Resources Created within a Compartment

(Note: If you are just starting on Oracle Cloud or new to Oracle Cloud Infrastructure (OCI), then I would suggest you check our previous post on Oracle Cloud Infrastructure (OCI) basic concepts i.e. Region, AD, Tenancy, Compartment, VCN, IAM, Storage Service etc)

Overview of Compartment

A compartment is a logical container, to organize and control access to the Oracle Cloud Infrastructure (OCI) Resources (Compute, Storage, Network, Load Balancer etc) created within that compartment and you impose some policies to that compartment, which restricts who can use the resources created within than compartment other than administrators of your account.

According to this Diagram,

• You create one compartment i.e  Central_IT Compartment. This compartment is a top-level compartment which has access to all Identity and Access Management resources in OCI, this team is a superuser and they will manage other users.
• Now within the same compartment, you create another compartment Central_IT_Network Compartment which manages the organization’s network like VCN, Internet Gateway, Load Balancer, DNS, FastConnect etc.
• Next, according to your business requirement you create more Compartments for Finance & HR team, who have access to finance and HR related resource like load Balancer, Object Storage, Database system, within these compartments, you can have sub-compartment like Fin Proj A, Fin Proj B, HR Proj A & HR Proj B, who have access to very limited resources like Virtual Machine (VM) & Security List.

Quick facts about Compartment

• [July 2019] Now Compartment can move to a different parent Compartment.
• [July 2019] Most of the OCI resources can now move from one compartment to another.
• [July 2019] Deleting compartment in Govt Cloud is not yet possible
• To delete a compartment, it must be empty of all resources
• [July 2019] we can create multilevel/Sub compartments and maximum as of now we can have 6 compartment levels.
• Compartments can be renamed or deleted (once all the associated resource are deleted or terminated from the compartment)
• Compartments are global meaning they span across Regions.
• When a tenancy is provisioned a root compartment is created
• Each resource belongs to a single compartment but resource can be shared across compartments
  • E.g. VCN & Subnet can be in a different compartment
• After creating a compartment, you need to write at least one policy for it, otherwise, resources inside compartment can’t be accessed (except Tenancy Admin)
• Policies n Higher Level do get inherited to sub-compartments.

How to Create a Compartment in OCI

1. Open the navigation menu. Under Governance and Administration, go to Identity and click Compartments.

2. A list of the compartments you have access to is displayed. Click on Create Compartment

3.  Enter the required details & click on Create Compartment

When creating a compartment, you must provide a name for it (maximum 100 characters, including letters, numbers, periods, hyphens, and underscores) that is unique within its parent compartment.

How to Grant Access in Compartments

• The very first thing After creating a compartment, you need to write at least one Policy for it, otherwise, no one can access it (except administrators or users who have permissions set at the tenancy level).
• When you create an access policy, you need to specify which compartment to attach it to.

Note:  Policy, attached to a group defines who can access what’s in a Tenancy or Compartment

Create OCI Resources in a Compartment

• To place or create a new resource (Compute, Storage, Database, VCN, etc) in a compartment, you simply select that compartment when creating the resource (the compartment is one of the required pieces of information to create a resource)

Moving OCI Resources to a different Compartment

Most resources can be moved after they are created. There are a few resources that you can’t move from one compartment to another. After you move the resource to the new compartment, the policies that govern the new compartment apply immediately and affect access to the resource.

Note: After a resource is moved to a new compartment, policies applicable to new compartment are applicable immediately, and affects access to the resource.

Moving Compartment to different Compartment

• From July 2019 onwards, you can also move a compartment to different parent compartment within the same tenancy
• When you move a compartment, all its contents (sub-compartment & resources) are moved with it
• To move a compartment, you must belong to a group that has
  manage all-resources permission on parent compartment of the current compartment that you want to move and destination compartment

Moving Compartment: Policy Implications

Use Case 1: Move Compartment C from B to D compartment (where policy is written at Root level)

You have one Tenancy (root Compartment), within this, you have Compartment A within this have another Compartment B & D and within Parent B compartment has Compartment C which we are moving to parent compartment D.

On root compartment level, we have written the policy to allow Group G1 to manage compartment A:B and Group G2 to manage A:D as soon as when we move Compartment C from parent B to parent D compartment Group G1 has no more access compartment C and Group G2 will get automatically get access to the compartment  C.  

Use Case 2: Move Compartment A from Test to Dev compartment (when Policy written at Operation Level)

In this use case, you have a tenancy (root Compartment), within this tenancy, you have operations like Test & Dev and within Test compartment, you have Compartment A which you are moving to Dev compartment.

In policy, we have allowed Group G1 to manage buckets in compartment Test: A at the operation level. As we have applied the Policies at operation level, Group G1 will automatically move Compartment A from test to Dev Compartment and Group G1 will not lose permission. In this case, Policy will be automatically updated for you.

Use Case 3: Move Compartment A from Test to Dev compartment (when Policy written at Test Level Compartment)

In this use case, you have a tenancy (root Compartment), within this tenancy, you have operations like Test & Dev and within Test compartment, you have Compartment A which you are moving to Dev compartment.

This time, Policies are written at Test level compartment instead of operation level compartment which says allow Group G1 to manage buckets in compartment A, and the policy will not be updated or this policy will be failed because Policy has been written at Test level, not on the operation level.

To move compartment A from Test to Dev you have to manually type policy at dev compartment where Group G1 to manage buckets in compartment A and existing policy must delete.

Use Case 4: Move Compartment A from Test to prod compartment inside HR (when Policy written at root level)

In this use case, you have a tenancy (root Compartment), within this tenancy, you have an operation and HR compartments and within this, you have test, dev & prod Compartment respectively. Now within a test compartment, you have Compartment A which you are moving to prod compartment.

In this, Policy is written at the root level so this policy has all way to go to Operation and test compartment so now this Policy will allow compartment A to go to prod compartment and Group G1 does not lose permission.

Note: If you want to know more about these use cases in detail check the video which mentions in this blog above.  

Moving Compartment: Restrictions

• You can’t move a compartment to a destination compartment with the same name as compartment being moved.
• Two compartments within the same parent cannot have the same name. Therefore you can’t move a compartment to a destination compartment where a compartment with the same name already exists.

Delete a Compartment in OCI

• To delete a compartment, it must be empty of all resources. Before you initiate deleting a compartment, be sure that all its resources have been moved, deleted, or terminated, including any policies attached to the compartment.
• Some resource types can’t be deleted, therefore, compartments containing these resource types can’t be deleted. A resource type that can’t be deleted is:
  • Data transfer jobs

Note: To know more about Deleting Compartments check my previous blog on  Oracle Cloud Infrastructure (OCI): Updates October 2018

Renaming a Compartment

• Compartments can be renamed and policy defined to that compartment will automatically be applied to the renamed compartment.

Note: You can’t change the name of your root compartment.

Viewing a Resources Created within a Compartment

• You can also view the resources created within a compartment,  select the type of resource you want to view. For example, click Database to view all your Database resources, it can be done from Console or via making API calls ie. from Command Line Interface (CLI)

Note: It’s not possible to get a list of all the resources created within a compartment by using a single API call. Instead, you can list all the resources of a given type in the compartment (e.g., all the instances, all the block storage volumes, etc.).
