This blog post discusses the steps to download the Software & Patches from My Oracle Support (MOS) using “Wget”.

In the production environment, due to the performance & security reasons, there is a firewall and a system policy which doesn’t allow the installation of a browser or the use of GUI. To work around this, we have Wget which enables us to download Software/Patches from My Oracle Support using the Linux Terminal.

Things Good To Know About Wget

Wget is a free utility for the non-interactive download of files from the web. It supports HTTP, HTTPS, and the FTP protocols, as well as the retrieval through HTTP proxies.
Wget is non-interactive i.e. it can work in the background while the user is not logged in which allows you to start a retrieval and disconnect from the system, letting Wget finish the work.
Wget has been designed for robustness over slow or unstable network connections; if a download fails due to a network problem, it will keep retrying until the whole file has been retrieved.

Steps To Download Software & Patches Using The Wget Script

For this, you will need another computer with GUI and browser-enabled.

1. Log in to MOS (http://support.oracle.com) & search for the software or patch whose Wget script you want.

MOS

2. Select the software or patch you want to download

WGET oracle EBS MOS script patch download E-Business suit erp

3. Click on the ‘Download’ button.

WGET oracle EBS MOS script patch download E-Business suit erp

4. Click on “WGET Options”.

WGET oracle EBS MOS script patch download E-Business suit erp

5. Click on the “Download.sh” button to download the script.

WGET oracle EBS MOS script patch download E-Business suit erp

6. Once you have downloaded the Wget script, copy it to the source environment where you want to download the software or patch.

7. Run the script and when it asks for the username & password, enter the My Oracle Support (MOS) username & password.

# SSO username and passwor
SSO_USERNAME=EXAMPLE@ORACLE.COM
SSO_PASSWORD=password

Now, the WGET script will execute and download the software/patch.

I hope you find this blog useful in terms of downloading the software or patches to your machine using the command line. If you have any doubts or facing any issue, please post it in the comments' section.

In this post, I will discuss an Overview of Oracle Autonomous Linux Operating System which was announced at Oracle OpenWorld 2019. I will also cover How to Create your First Autonomous Linux on Oracle Cloud & access it over the Internet.

Note: In my previous episode (https://k21academy.com/31), I covered the 8 Important Key takeaways from Oracle OpenWorld 2019 & the 1st point was about World’s First Operating System or Autonomous Linux.

Now, before I show you how to create a step-by-step Oracle Autonomous Linux & how to access it, let’s first understand what exactly is Oracle Autonomous Linux.

Overview Of Oracle Autonomous Linux

1) Oracle Autonomous Linux is based on the native Oracle Linux operating environment along with the new Oracle OS Management Service.

2) It uses Machine Learning (ML) & Artificial Intelligence (AI) to deliver security & Lifecycle Management like Autoscaling, Management & Monitoring of operating system.

3) Oracle Autonomous Linux executes automatic patch updates and tune without human interaction, thus improving user productivity, more security, and less downtime.

4) Oracle Autonomous Linux is binary-compatible with Red Hat Enterprise Linux, allowing IBM Red Hat customers to immediately start using the service with their current applications on Oracle Cloud Infrastructure.

5) Last but not least, it is available with Oracle Linux Premier Support at no additional cost to Oracle Cloud customers.

How to Create Oracle Autonomous Linux

1) Register & Log into the Oracle Cloud account, cloud.oracle.com

Note: First, you should have an Account at Oracle Cloud and if you don’t have one, then you can register FREE using my step-by-step video & guide that I covered in episode 30. You can get it by visiting k21academy.com/30 or k21academy.com/cloud01.

2) Configure Network: Next, as we want to access this Autonomous OS over the internet, so we’ll create it in the Public Subnet and assign Public IP in addition to configuring Internet Gateway on VCN.

Note: If you are not familiar with VCN, Subnet or Internet Gateway then learn about them in one of my previous episodes on networking at http://k21academy.com/1z093215. Trust me, it is easy and should not take more than 15-20 minutes. If you hit an issue, leave a comment and either I or someone from my team will help you.

3) Generate SSH Keys: Once you are done with creating VCN & Public Subnet, then you also need one more thing i.e. SSH Keys Pair that you generate using Puttygen, so that you can access the Autonomous Linux using SSH private key.

Note: If you are new to SSH Keys or don’t have one, then create them using the step-by-step guide that we use in our Oracle Cloud Training. Check at https://k21academy.com/oci51.

4) Sign In: Once you have all the things sorted, sign in to Oracle Cloud Account, and you will land on the OCI Console.

5) Create Autonomous Instance: Click on the hamburger menu on the top left side, select Compute & then Click on Instances.

6) Click on “Create Instances”.

7) Enter the name of the Instance, & Click on “Change Image source“.

8) Under Oracle Images, Choose Oracle Autonomous Linux. Scroll Down, Accept the T&C & Click on “Select Image”.

9) Then choose Availability Domain inside which you want to create the Instance, If you want higher CPU & higher memory, then click on “Change Shape“.

Note: Want to know more about Region & Availability Domain in OCI, then click HERE.

10) Now, Under networking, choose the VCN & a Public Subnet (we are choosing Public Subnet because we want to assign Public IP to the Instance). Make sure you check the “Assign Public IP” box. Leave all the field by default & under “Add SSH key”, Copy the content of SSH Public key. Click on “Create”.

11) A few minutes later, you will notice that the status of the Instance has changed from Provisioning to Running. You will get a Public IP you can use to connect to the Instance through PUTTY.

Provision Autonomous Linux Instance

Connect to the Oracle Autonomous Linux Instance

1) To connect to the Instance you will need the Public IP of the Instance & the PuTTY Software.

Enter the Public IP Address in the Hostname, then add the SSH Private key (That we created before) under SSH & then Auth. Click on “Open”.

Adding Private Key in PUTTY

In this blog post, I will discuss Oracle Database on Cloud different choices & options you have for On-premise as well as for Oracle Cloud. It comes with options like:

Database Cloud Service on Virtual Machine (VMDB) or Bare Metal (BMDB)
Exadata on Cloud (ExaCS) or Exadata Cloud@Customer (ExaCC)
Autonomous (ATP & ADW) with two deployment options: Serverless or Dedicated

I will also discuss What are these various Databases on Cloud deployment options, When to use what, Who controls what in these deployment options?

Database Choices & Options

In the diagram shown below, from left to right are the On-premises platform choices (i.e. all manual tasks), Automated, and Cloud choices (i.e. Autonomous). Database Choices & Options

Traditional Database Deployment: The most common deployment model prior to the evolution of the Cloud where your DB is on the commodity hardware.
Oracle Exadata On-premises: You will purchase Exadata and deploy your database & heavy workload on Exadata On-premise.
Exadata Cloud@Customer: Instead of purchasing, you subscribe to the Exadata machine and work on a pay-as-you-go model.
DB on Compute (OCI): This is similar to the first option, however instead of running on-premise, you are running it on Cloud (you will not get any tooling).
DBCS (VMDB & BMDB): Databases run on OCI as a DBCS & this is where you get all the Cloud tooling like automated cloning, patching, backing up & restoring.
Exadata Cloud Service: Running Exadata but on Cloud, you subscribe to either a Quater rack, Half rack or a full rack. (Note: To know more about Oracle Exadata Cloud Service(ExaCS) Architecture, click HERE)
Autonomous DB Serverless: You will get the database but no access to the Autonomous DB host.
Autonomous DB Dedicated: A dedicated Exadata infrastructure is assigned to you, on top of that you create a container DB, and on that, you can create multiple pluggable databases.

(Note: As of now, Dedicated only supports ATP)

Database Operations

Check below to look at what controls you have, for these different Databases on the Cloud as well as On-premise.

The post Oracle Database Cloud Service Certification 1Z0-998 & 1Z0-931: Step by Step Hands-On Guides To Clear Exam appeared first on Oracle Trainings.

This post covers the Overview of Data Guard (Standby Database) in Oracle Cloud Infrastructure (OCI).

If you are new to Oracle Cloud Infrastructure(OCI) then check what is Region, AD, FD, Tenancy, Compartment, VCN, IAM, Storage Service, Click here
If you are new to Database in Oracle Cloud (OCI), then check 9 things every beginner should know for Database on OCI Click here

Introduction To Data Guard

Oracle Data Guard enables & ensures high availability, data protection, and disaster recovery for your enterprise database.

Oracle Data Guard provides an extensive set of services that create, maintain, manage, and monitor one or more standby databases to enable production Oracle databases to survive disasters (such as natural calamities) and data corruption.

Active DataGuard vs Normal DataGuard

Oracle Data Guard maintains these standby databases as a cloned version of the production database and regularly applies changes from Primary Database to Standby Database. Then, If the production database becomes unavailable because of a planned or an unplanned outage, Oracle Data Guard can switch any standby database to the primary role, minimizing the downtime associated with the outage.

You Can Configure Two Type of Data Guard based on our requirement

1) Active Data Guard: Active Data Guard enables read-only access to a physical standby database for queries, sorting, reporting, Web-based access, and so on, while continuously applying changes received from the primary database.

Note: For Active Data Guard, when you create the database, you need to select the Extreme Performance

There are 4 different types of editions in Oracle Cloud, Enterprise Edition, Standard Edition, High-Performance & Extreme Performance.

Active Data Guard

2) Normal Data Guard: Normal Data Guard enables you to switch to the Standby Database when your primary database is down due to some outage or natural calamities. In normal Data guard, you can still open the standby database in read-mode but changes not applied while in read-only mode.

Types: Physical | Logical | Snapshot

Physical: Redo logs are Shipped & Applied on Standby Database
Logical: Mainly used for Rolling Upgrades & Redo logs are shipped & transformed to SQL & then they are applied.
Snapshot: A snapshot Standby Database receives and archives, but does not apply redo logs data from a primary database.

For Standby Database, Recovery Type can be Manual or Automatic and Recovery Point can be Full Recovery or Point in Time.

Data Guard in Oracle Cloud: Key Points

1) There are 3 different types of Database in Oracle Cloud & depending on the type of DB, you will use different tools to configure Data Guard

Database Can be deployed in 3 ways:

Database on Compute: You follow the manual method of creating a Data Guard.
User Managed Database: You will use Oracle OCI Cloud tooling (dbcli, dbaascli, OCI Console) to configure Data Guard
Autonomous Database: Data Gaurd concept is Not applicable

2) Data Guard is currently available within Region.

3) To configure DG across the region or with On-premise or more than 1 standby, you will use manual method DGMGRL

4) By default, you will only get 1 Standby Database, so if you have the requirement of more than one then can configure using console / CLI

5) For ExadataCS, you need two Exadata DB Systems for Data Guard, one acting as Primary Database and another one as Standby Database.

6) For BM DB & ExaCS: DB system to be used as standby must be ready before DB association

7) If you have a VM DB, you can simply go to the Database system & configure a New Standby DB System by enabling the Data Guard.

8) Both Primary & Standby DB systems must be in the same compartment, and they must be the same shape, to know more about Compartment click here

9) By Default Exadata comes with Extreme Performance, so you can configure Active Data Gaurd in this

Note: Oracle Active Data Guard provides read-only access to the physical standby database while it is synchronized with the primary database, enabling minimal latency between reporting and transactional data. Check more here

If you are new to ExaCS then look at the Architecture here

10) For BM DB & ExaCS: DB system to be used as standby must be ready before DB association

11) Both DB must be in same VCN but can be in different Subnet & port 1521 should be open across subnet using Security List or NSG, To know more check here

12) It is recommended to have Standby DB on different AD from Primary DB. To know more about Region & Ad in OCI, click here

13) If you are working in Region which has one AD, then configure the Data Guard in different Fault Domain (FD).

Check what is Region, AD, FD, Tenancy, Compartment, VCN Click here

Fast- Start Failover (FSFO)

Fast-Start Failover is a feature that allows the Oracle Data Guard broker to failover a failed primary database automatically to a predetermined standby database. This feature increases the availability of the database by eliminating the need for DBA involvement as part of the failover process.

The best practice for high availability and durability is to run the primary, standby, and observer in separate availability domains.

Now it’s your turn to post your doubts in the comment section and let us know where you are facing challenges in Oracle Cloud Infrastructure

The post Data Guard In Oracle Cloud Infrastructure (OCI): Overview & Concepts appeared first on Oracle Trainings.

This post covers the Roles, Responsibilities & Tasks performed by DBAs & Apps DBAs in Oracle Cloud (OCI).

Roles / Tasks of Oracle Cloud DBA / Apps DBAs

One of the most common questions being asked in our private Facebook Group dedicated to Oracle Cloud and those who have joined our Oracle Database Cloud Service Training is about Role of Cloud DBA

Looking at so many requests, here I have discussed, How the Role of DBA changes with Cloud and how the Roles and Responsibilities change as you upgrade yourself from DBA to Cloud DBA.

1) Design & Deployment of Database

The first thing you as a senior Cloud DBA or Architect will be doing is designing & need to decide where you deploy these Databases.

Is it Autonomous DB, User-Managed DB (Automated) or Database on Compute (which doesn’t include Cloud Tooling). To know more about Database types, check here
Once you decide the Database type, then you will decide in which Region & AD to deploy this Database.
You also need to decide if you want to configure High Availability (HA) & Disaster Recovery (DR) like RAC & Data Guard

2) Provision Database

Once you have done the designing part then next will come is Provisioning of Database.

In order to provision the database, you should have the knowledge of the pre-requisites depending upon whether you are setting up an Autonomous Database, User-Managed Database or you are simply deploying a Database on Compute

You should be familiar with Pre-requisites like Network Setup connectivity (VCN, Subent, Security rules). To know more in details check here
The different types of Editions (SE, EE, HP, EP) Note, for Exadata it’s always Extreme Performance
The SSH keys which is used to connect the DB Instance. Note: To know more about How to Generate SSH Key Pair for Oracle Cloud (Windows/Linux), click here

Note: To know more about how to Provision a Database on oracle cloud (OCI) check here

3) Connectivity

The third thing you should know about is Connectivity

There are different ways to connect from the On-premise to the Oracle Cloud, like VPN Connect and Fast Connect. To know more in details about 3 ways to Connect to the Oracle Cloud, Check here
In the case of the Autonomous Database, you should be familiar with the Client Credentials, how to download them & how to make connectivity. To know more about How to Connect to the Autonomous Database on Oracle Cloud, Check here
Also, you should have knowledge of Network connectivity, things like Security List (SL) & Network Security Groups (NSG) which are kind of firewalls in Oracle Public Cloud. To know more about Network Security Groups (NSGs) Vs. Security List (SL): When to use What? Check here

ADW connectivity

Oracle Cloud: Security Rules

To allow/block incoming & outgoing connections, A security list provides a virtual firewall for an instance, with ingress and egress rules that specify the types of traffic allowed in and out. To know more about Security Rules, please check here

4) Administration

Then the other responsibilities of DBAs are Administration.

It is the main functionality, so you will be looking for things like:

Performance Tuning (Using the Performance Hub or Service Console for Autonomous DB)
Scaling up & Scaling down of the services (CPU, disk space or memory)
Cloning
Access controls, and resetting the passwords.

Other tasks are maybe adding the SSH keys or terminating the Database, start and stop the databases.

5) Patching

The 5th thing you will be doing is Patching.

Database Patching
Grid Infrastructure
Cloud tooling
Operating systems patches

You have to apply patches to the Automated Databases or User-Managed Databases i.e VM DB, BM DB and Exadata Cloud Service.

Note: Patching in the Autonomous database is being taken care of by Oracle.

As an Oracle Cloud DBA, you need to learn new tools for Start/Stop i.e. dbcli and dbaascli(Database as a Service Command Line Interface) or Database Service Console to perform the patching.

6) Backup & Restore

The Sixth task will be Backup & Restore.

Oracle provides you all the necessary tools to back up the databases on the cloud but you have to configure the backup scenarios. Backup methods like schedules backup or on time backup will be configured you still have to do the Back-up and Recovery using new tools and Oracle Object Storage Service (Swift storage)

7) Security

In my view, Security is the most important thing apart from Lift & Shift

All the cloud vendors work on a shared security model in which some of the responsibility lies to the Cloud vendor and some to the customer.

Recently, Oracle announced Three new Security Services in Oracle OpenWorld 2019 that have been added: Oracle Datasafe, Cloud Guard, and Maximum Security Zone.

We are starting our new batch for DBA to Cloud DBA Training for 30th November 2019, in this, we will cover these new security features. (For FREE Masterclass, check here)

Note: To know more about the Compartment & Policy In oracle Cloud, Check here

8) Migration (Lift & Shift)

Once the security is done then you will be doing migration Lift & shift

In this task, you will be migrating your databases from on-premise to the cloud. Oracle provides you a lot of migration options like ZDM( Zero Downtime), MV2ADB (move to ADB), SQL Developer, Data-Pump, RMAN, Plug-Unplug, etc.

You will also have migration methods like physical, logical, offline or online, etc.

Migration Method

Above all the tasks are undertaken by a CloudDBA.

Note: To know more in details about Migration Autonomous Database Cloud Options: Data Pump, SQL Loader, DBMS_CLOUD, GoldenGate, Check here

For Apps DBAs

1) EBS Cloud Manager (EBS CM)

If you are an Apps DBA, Working on E-Bussiness Suite, PeopleSoft, JD Edwards then you have a few additional roles & responsibilities.

You will be managing your application like EBS or Peoplesoft on Cloud & for that, you have EBS Cloud Manager which is a GUI to build, manage & migrate application on cloud. Also, it will be used for Migrating & cloning applications on the cloud.

Note: To know more about EBS Cloud Manager in detail, check here
Note: To know more in details about Lift & Shift Migration to Cloud, check here & here

Migration EBS CM

So as shown in the video above, the role of Oracle DBA will transition to Oracle Cloud DBA. A quote from Charles Darwin “It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.”

1) The very first thing you should know before starting your Cloud journey is the Cloud Service Models i.e. SaaS, PaaS & Iaas. As a DBA, you will work on PaaS & Iaas. To know about Cloud Service Models, check Here.

2) IaaS in Oracle Cloud is available in two flavors: OCI & OCI-C. As a Cloud DBA, you work to manage Database on OCI. Cloud at Customer (C@C) is currently using OCI-C and is slowly transitioning to OCI.

To know more about the basic services in Oracle Cloud Infrastructure (OCI), check Here and to understand the differences between OCI & OCI-C, check Here.

OCI vs OCI-C

3) In OCI, there are two categories for the Database: User-Managed & Autonomous Database.

4) In the User-Managed Database, there are three deployment models: VM DB System, BM DB System, and the Exadata DB System.

Virtual Machine DB Systems: Database is running on Virtual Machine & It supports both 1 -node, and 2-node RAC DB systems on Virtual Machine.
Bare Metal DB System: Database is running on Bare Metal & It only supports only 1-node DB systems (RAC is not supported)
Note: Where A bare metal server is a “single-tenant” physical server. This means that the server is dedicated to one customer and not shared between multiple customers & A virtual server is hosted in a “multi-tenant” environment. This is where multiple virtual servers share the same physical hardware.
Exadata DB System: Exadata DB systems runs on Exadata on Cloud and consist of a quarter rack, half rack, or full rack of compute nodes and storage servers, tied together by a high-speed, low-latency InfiniBand network and intelligent Exadata software and it is always a 2-node RAC only.

OCI User Managed Database Choices

5) Database Editions Supported In OCI

All 1- node RAC DB systems support the following Oracle Database editions:

Standard Edition
Enterprise Edition
Enterprise Edition – High Performance
Enterprise Edition – Extreme Performance (required for 2-node RAC DB systems)

Note: RAC is only supported in VM DB System & Bare Metal DB System

6) Autonomous Database: Oracle Cloud Infrastructure‘s Autonomous Database is fully managed by Oracle such as patching and another administrating task. Autonomous Database is further divided into types:

ADW: ADW stands for Autonomous Data Warehouse and used for decision support or data warehouse workload.
ATP: ATP stands for Autonomous Transaction Processing and used for a transactional workload.

To know more about Autonomous Database, Click here.

7) For the User-Managed Database, you will be performing the following tasks:

Configuring DB systems on OCI.
Managing DB system (Start, Stop Scale-Up/Down) & DBCLI.
Patching DB system using Console & CLI.
Configuring & Monitoring a DB on OCI.
Backing up and Recovering a DB on OCI.
Configuring Data Guard For HA
Migrating (Lift & Shift) On-prem Database to Cloud (OCI). To know more about Migration, check Here.

8) For the Autonomous Database, the task you will perform includes:

Provisioning ADW.
Connecting DB with Application.
Migrating from On-Prem to Cloud.
Performance Tuning & Monitoring.
Loading Data into the Autonomous Database. To know more, check Here.
Configuring Reporting & Analytics.
Backup & Restoring ADW & ATP.
Scale-Up & Scale-Down.

9) Currently, there are 3 certifications available for Database on Cloud:

For Autonomous Database, [1Z0-931] Oracle Autonomous Database Cloud Certified Specialist.
For Database 0n OCI, [1Z0-998] Oracle Database Cloud Service Certification.
For Database on OCI-C, [1Z0-160] Oracle Database Cloud Service Certification.

The post Oracle Cloud for DBAs: 9 Things Every Beginner Should Know appeared first on Oracle Trainings.

This post covers How To Create Database on Oracle’s Gen2 Cloud (OCI).

Database Deployment

We can deploy User-managed Database In Oracle Gen2 Cloud (OCI) either on Virtual machine (VM), Bare Metal (BM) or on Exadata CS, In this post, I have covered the steps for VM-DB but concepts remain more or less same for BM & Exadata CS too.

Note: To know more about Oracle Cloud Database Options (VMDB, BMDB, ExaCS, ExaCS & Autonomous (ADW, ATP), Check here

So Let’s look at Deployment on Cloud so two main Deployment Model on Public Subnet. In order to understand this, there is VCN (this is network) & Subnet which is VCN divided into smaller parts.

Database Deployed On Private Subnet

Database Host on a private subnet listen on a Private IP, We recommend the Deploying database on a private subnet & you will be able to access the database within the Virtual Cloud Network. You can also access it from the on-premise network using DRG (Dynamic Routing Gateway).

Database_In_Private_Subnet

Database Deployed On Public Subnet

A database running on Public Subnet will get both Private IP & Public IP, you will be able to access it via Public IP & Internet Gateway is required for connectivity.

Database_In_Public_Subnet

We only recommend creating a database on the public subnet only when you are using this database for testing purposes or if you want to expose your database to the internet.

Note: To know more about VCN, Subnet, Firewall (Security List), IGW, DRG & how to create it, check here

How to Create Database on Oracle Cloud

1) Register & Log in to the Oracle Cloud account, cloud.oracle.com

2) Configure Network: Next, as we want to access the database over the internet, so we’ll create it in the Public Subnet and assign Public IP in addition to configuring Internet Gateway on VCN.

Note: If you are new to SSH Keys or don’t have one, then create them using the step-by-step guide that we use in our Oracle Cloud Training. Check at https://k21academy.com/oci51.

4) Sign In: Once you have all the things sorted, sign in to Oracle Cloud Account, and you will land on the OCI Console.

5) Create Database Instance: Click on the hamburger menu on the top left side, select Bare metal, VM & Exadata & then Click on Create DB System.

6) Enter the name of DB System, Then choose Availability Domain inside which you want to create the Instance, If you want higher CPU & higher memory, then click on “Change Shape“.

Note: Want to know more about Region & Availability Domain in OCI, then click HERE.

DB on Oracle Cloud

7) Under “Add Public SSH key”, Copy the content of SSH Public key.

8) Select the VCN & Public Subnet, then click on Next

Database on Oracle Cloud

9) Enter the DB Name, & select the Database version. Create the SYS admin password (make sure you remember the password)

Note: The password must be nine to thirty characters and contain at least two uppercase, two lowercase, two numeric, and two special characters. The special characters must be _, #, or –

10) When the database creation is complete, the status changes from Provisioning to Available

Database creation

Note: It will take 50-60 minutes to make your instance up & Running

Provision Database

How To Connect

1) In order to connect to Database Host deployed in Oracle Gen2 Cloud (OCI), you need to open port 22, which is SSH port and you will be able to connect to your database Instance and port 1521 which is database port, so that your database will be able to talk to application or other services over internet.

Note: When you create VCN using default options various resources are by default created by Oracle (Security List, IGW, Route Table).

To know how to create a security list and open port in Oracle Gen2 Cloud check here

2) To connect to the Instance you will need the Public IP of the Instance & the PuTTY Software.

Note: To know how to get the Public IP of the Database, check here

Enter the Public IP Address in the Hostname, then add the SSH Private key (That we created before) under SSH & then Auth. Click on “Open”

The post How To Create Database on Oracle’s Gen2 Cloud (OCI) appeared first on Oracle Trainings.

Oracle recently introduces a new feature to control the performance of Block Volume, which is the Volume Performance Unit(VPU).

In this blog, I will cover the overview of Block Volume & How to increase the Performance of Block Volume. To understand it better lets first understand the measuring unit – Volume Performance Unit (VPU).

What is Block Volume?

It provides high-performance constant cloud storage in a wide range of applications workloads. The Block Volume helps to provide network storage that can be used with the OCI instances.

Note: To know more about Oracle Cloud Infrastructure (OCI) Object, Block, File Storage, Data Transfer Service, check here

Volume Performance Unit (VPU)

Measured in terms of IO per sec and Throughput per GB.
Higher IOPS and throughput corresponds to higher VPU.
VPU is inversely proportional to the cost of the storage.
Oracle charges it as performance units per GB per month.

For Block Volume Elastic Performance now we have 3 configuration options that can be dynamically changed as per the requirement.

How to Increase Performance?

1) Register & Log in to the Oracle Cloud account, cloud.oracle.com

2) Sign In: Once you have all the things sorted, sign in to Oracle Cloud Account, and you will land on the OCI Console.

Block Volume Performance

From the OCI console we can get this feature for the new as well as existing Block volumes.

Comparision

Below table will have all the details of all the 3 modes of Block Volume – Elastic performance

To understand the relation between VPU, throughput and IOPS check the below graph. Where it indicates that for Lower there is no VPU involved and its only storage and for Balance and Higher performance.

On the Storage pricing, oracle has added Block Volume Performance unit which is priced as

Performance Units Per GB / Month

0 VPUs at $0 for Lower Cost
10 VPUs at $0.017 for Balanced
20 VPUs at $0.034 for Higher Performance

As of now, OCI Block Volume Elastic Performance has 2 limitations

Only change Block volumes elastic performance configuration on three volumes concurrently per tenancy
Boot volumes have 2 options only Balanced or Higher performance

This feature is definitely going to help the customer on the performance side and save costs as well. It’s easy to manage and can be controlled with Console, API, CLI and being dynamic in nature it makes it the best option as well.

The post 1Z0-1072 | Oracle Cloud Infrastructure 2019 Architect Associate appeared first on Oracle Trainings.

In this post, I have discussed which is the right Cloud to learn for DBAs, AppsDBAs or anyone working on Oracle applications like E-business Suite, PeopleSoft, JD Edwards, or Fusion Middleware like Weblogic, SOA, OBIEE, etc

Is it Amazon AWS, or Microsoft Azure, or Oracle’s Gen 2 Cloud (OCI).

It is the most common question which I have been asked frequently in our FREE Masterclass or in our FREE Facebook Community so I think of discussing the same with our Trainer & Cloud Expert Rajeev.

“I am an Oracle DBA/Apps DBA and “Confused between Oracle Cloud, Amazon AWS & Microsoft AZURE” which platform to learn or where should I focus?”

Well, If you would have asked this question to me a few years back, I would have said AWS without a doubt.

A lot has changed since then especially in last 2-3 years where Oracle introduced its Gen 2 Cloud which is OCI (Oracle Cloud Infrastructure) & also Oracle Exadata on Cloud (ExaCS), Autonomous Database for DBA’s or Cloud Tooling like EBS Cloud Manager

Now, you will also get Exadata on a Pay as you Go model in Cloud. To know more about Oracle Cloud at Customers(C@C) check here

OCI Services

Exadata on Cloud

Cloud for DBAs: AWS | Oracle Cloud | AZURE

In order to get the right answer for you, first, you need to understand what offerings we are getting from these Cloud Vendors.

If we look at the Cloud Offerings (SaaS, PaaS, IaaS). IaaS is Amazon’s Strong area, PaaS is AZURE’s strong area, but there is no vendor that can provide IaaS, SaaS & PaaS as good as Oracle. AWS or AZURE or Oracle Cloud

Note: If you look at the database management system analysis run by Gartner, In the market share, the Oracle is the number 1 player & The Future of Database Management Systems is Cloud!

Cloud Service Models

As a DBA, you will work on PaaS & Iaas. To know about Cloud Service Models, check Here.

If you look at above two diagrams (from our Oracle Cloud Training for DBA’s), there are three service Models in Cloud:

1. SaaS:

Stands for Software as a Service, where almost everything is handled by Cloud vendors like Oracle, SalesForce or Google (for Gmail), etc. All clients need is to buy a license and start using Service. Example of SaaS from Oracle includes Fusion Applications, ERP Cloud.

(Note: ERP Cloud is different than E-Business (R12) or Peoplesoft on Cloud – These comes under IaaS & PaaS Category).
Note: There is not many roles for DBA’s in Oracle SaaS except export/import of data or creating connections to other Cloud Account or On-Premise Account or Load Users.

2. PaaS:

Stands for Platform as a Service, where a platform like a Database or Application Server or Web Server is provided by Cloud Vendor on Cloud with all the tools necessary manage these. Clients (and You as Cloud Admin) still need to patch or do backup & recovery or Upgrade or Clone specific platforms like Database or Application Server in PaaS.

You, however, get the necessary tools from Cloud Vendor (like DBaaSCLI to patch & Restore, bkup_cli for Backup) so that you as Cloud Admin can do these tasks by a click of a button or using REST API.

Oracle Database is part of Database Cloud Service (DBCS) and is under PaaS Offering.

Note: There is a lot of work for DBA’s in Oracle PaaS, for a full list of Roles/tasks performed by DBA’s in Cloud check at https://k21academy.com/cloud12

3. IaaS:

Stands for Infrastructure as a Service, where all you get is like CPU, Memory, Disk, and Networking. Clients (and You as Cloud Admin) still needs to install O.S., Install Database and do all the task like On-Premise and without Platform Tools like DBaaSCLI or bkup_api or DBaaS Monitor or dbcscli, etc.

Running and managing the database on IaaS is not much different than traditional On-Premise Style (except that you save time & money in purchasing hardware).

When you run Database on IaaS Service Model, You loose out benefits of running Database in PaaS Service Model (DBCS) like One Click Patch or Automated Backup Configuration, simple Clone using the click of a button and lot more.

Performance

If you look at the price for performance, you would see that most of the other vendors are having a greater possibility in terms of taking more money from you as a customer, but from Oracle, you would get a better price to performance

Note: Local NVMe SSD, Oracle provides for DBaaS are superior to EBS storage Amazon provides for RDS

Oracle on Oracle for Great Experience

In terms of Great Experience, You don’t have all the application certified in AWS or AZURE, you don’t have RAC certified on AWS, you don’t have Exadata on AWS.

If you want to have Great Experience, Better Performance & wanted to have Great Pricing, All these included in Oracle Cloud that is on Oracle Cloud Infrastructure(OCI)

AWS Aurora RDS vs Oracle Database Cloud Service

AWS stands for Amazon Web Services and Relational Database Service from Amazon is Aurora

There is no doubt that Amazon is leader in IaaS (followed by Microsoft Azure, Oracle is catching up with next Generation Bare Metal Cloud Service now called Oracle Cloud Infrastructure) but if you look at Database Market, Oracle is Leader (No. 1) in Database with 41.6% Market Share (Source: DBEngine).

I am a DBA: Should I go for Amazon AWS, AZURE or Oracle Cloud

Now to the actual question, If you look at all the above points, Oracle being a leader in Database and given Oracle’s huge investment in the last 2-3 years in Cloud, and your existing experience as Oracle DBA, you can decide the right option for you.

Think from the Clients point of view, would they be comfortable running Oracle Database on Oracle Cloud (with all DBCS features & Tools) or Oracle Database on Amazon AWS (IaaS Offering) with very little Cloud Benefits.

If you trust and believe me, Oracle Cloud (Database Cloud Service – DBCS) is a much better option for DBAs & Apps DBAs (Once you learn and become Expert in Oracle Cloud for DBA’s then, by all means, pick AWS IaaS).

What’s your suggestion for DBA’s thinking of Cloud? What would you do?

In this Post, We covered how to Connect an Autonomous Database using In- Built SQL Developer Web and run PL/SQL Query.

Oracle SQL Developer Web Overview

To Connect to Autonomous Database there are various Database tools option available like SQL Developer Web, SQL Developer Client, SQL*Plus, and SQLcl etc.

Here, we are discussing about SQL Developer Web , because it is a browser-based application that provide many of administration features of desktop-based Oracle SQL Developer. SQL Developer Web is bundled with each Autonomous Data Warehouse instance.

To connect with Oracle SQL Developer Web, you must create Oracle Autonomous Database in Oracle Cloud , and the ADMIN user is pre-enabled for SQL Developer Web.

The main features of SQL Developer Web are:

Run SQL statements and scripts in the worksheet
Export data
Design Data Modeler diagrams using existing objects

Connect with Built-in SQL Developer Web in ADB

1). Register to the Oracle Cloud account

First, you should have an Account at Oracle Cloud and if you don’t have one, then you can register FREE using step-by-step video & guide that we have covered in episode 30. You can get it by visiting k21academy.com/30.

2). Create and Access to an instance of Autonomous Data Warehouse

Once you have your own Cloud account, then create your first Autonomous Data Warehouse instance on Oracle Cloud Infrastructure (OCI), if you don’t know how to create ADW Instance, you can check from here.

3). Access SQL Developer Web as ADMIN

Third step, to access SQL Developer Web you can use the Oracle Cloud Infrastructure console or the Autonomous Data Warehouse Service Console.

To access SQL Developer Web from the Autonomous Data Warehouse Service Console:

On the instance details page click Service Console–>Development–>SQL Developer Web

In the SQL Developer Web Sign in page, enter your Username and Password, Click Sign in.

This shows the SQL Developer Worksheet tab.

Oracle listens to its users and with huge demand, Oracle released Block Volume Sharing in reading/Write Mode…Wow!!! This will definitely be going to ease much design and lower the storage cost too. Till now Block volume can be attached to only one compute instance at a time and for Storage share, we have File System Service.

This post covers the new feature from Oracle that allows us to share Block Volume with Multiple Instances.

If you are new to Oracle Cloud, check our FREE Guide to Register for Oracle Cloud Trial Account

Storage Options in Oracle Cloud

Oracle Cloud Infrastructure offers below main storage service

Block Volume Service: Block storage operates at the raw storage device level and manages data as a set of numbered, fixed-size blocks using protocols such as iSCSI.
Object Storage Service: Object storage is independent of a server and accessed over the Internet. Data is managed as objects using an API built on standard HTTP verbs. It is an ideal storage platform to store very large amounts of data.
Local storage: Local NVMe-based SSD storage with very high IOPS and low latency is available for the Storage Optimized Instance Type (e.g. BM.DenseIO2.52).
File Storage Service (FSS): Fully managed file storage service.NFS3 along with Network Lock Manager (NLM).It Starts from a few KBs to 8 Exabytes (EB)
and Data & Metadata are encrypted at rest

To know more about the types of storage in Oracle, check our post, Oracle Cloud Infrastructure (OCI) | Storage Object, Block | File Storage, Data Transfer Service|, here

OCI Block Storage

Points to be noted here:

Available for DBCS since May 2017 and now it is available to the public.
Default attachment from Compute is non-shareable and exclusive read/write
Two options introduced Read/Write Sharable and Read-only Sharable.

Sharable Block Volume

Read-only attachment is available in sharable mode to multiple instances.
No need for concurrency access control or cluster-ware solution for Read-only sharable block volume across multiple readers.
Volume groups, Disk-to-Disk Clone, automated backups are available for Shared Block Volumes.
Available in all regions via OCI Console, CLI, SDK, Terraform.
Other vendors provide only Read-only Block Volumes but have a limitation on Read-Write shareable attach.

Possible Use Cases

With the Shared Block Volume (Read-Write of Read-Only attach) can be useful in various deployments and designs. Listing a few of them:

I hope you find this blog useful in understanding the latest enhancement on block volume and its several use cases.

This post covers issues & fix which I have encountered while doing hands-on for our EBS On OCI Training while setting up EBS Cloud Manager In Oracle Cloud Infrastructure (OCI).

If you don’t know about EBS Cloud Manager check our previous post on Oracle EBS(R12) Cloud Manager Overview: What & How & also check our latest post covering latest release of EBS Cloud Manager (19.3.1)

Introduction config.pl

Once you have successfully created the EBS Cloud Manager instance, then to make it functional you need to run configure.pl script.
Configure.pl scripts to create a configuration file that contains the value of the user authenticated to use EBS Cloud manager, compartments, groups, network, etc.
It is a one-time activity and then you can use EBS Cloud Manager for Deploying Oracle E-Business Suite R12 on OCI either a Fresh or vision Install or you can install using the backup which you have taken.

Issue Encountered

While running the config.pl for the first time for configuring EBS Cloud Manager, I hit with an error as

Error: “Failed to execute command /bin/bash -c ” source /u01/install/APPS/software/oracle-bmcs-cli/bin/activate ; export LC_ALL=en_US.utf8 ; export LANG=en_US.utf8 ; oci compute instance list-vnics –instance-id ocid1.instance.oc1.iad.anuwcljs77qm3eyc33qs2hr3suee3eyqmtewh7m7bi5nbmfq72kjpmagtzwq –config-file /u01/install/APPS/.oci/ebscm.admin && deactivate ”

EBS Cloud Manager

The above error doesn’t much reveal about the cause, so I tried looking into the EBS Cloud Manager log file: /u01/install/APPS/apps-unlimited-ebs/out/configure_2019-12-24_XX & I found another error which is more clear and I able to troubleshoot the issue.

EBS Cloud Manager

Root Cause

There might be several reasons for the above error which I have encountered.

The wrong username is given while configuring EBS Cloud Manager using config.pl
User is not authorized to perform the task, refer section 2.2 Create Groups and Assign Policies from Doc ID: 2434500.1 and if you have given all the policies. To know more about the policy check here
EBS Cloud Manager is created in the wrong compartment. With the release of EBS Cloud Manager 19.1.1 its supports separation of duties which Each resource should be created in different Compartments. For Example

- Network-Compartment will hold network-related resources
- EBS CM -Compartment will hold EBS CM Virtual Machine
- EBSDEMODBA-Compartment will hold EBS & Database

EBS Cloud Manager

Fix

After deep-diving into the error, I found that I have created the EBS Cloud Manager VM in the wrong compartment ie. in Network -Compartment wherein it needs to be created in EBSCM-Compartment, so after re-creating the EBS CM Virtual machine in EBSCM-Compartment the issue has been resolved.

EBS cloud Manager

I hope you find this blog useful in troubleshooting the EBS Cloud Manager issue while running the config.pl for the first. If you like the post please share this your colleague or friends who are working on EBS Cloud Manager For EBS Deployment in Oracle Cloud Infrastructure.
