This Post covers options for integrating Oracle E-Business Suite with Oracle Identity Management products or if you’re upgrading from EBS 11i to 12, or perhaps also switching from the older Oracle Single Sign-On technology to Oracle Access Manager.

Before proceeding to the High-level Integration of E-Business suite with Oracle Single Sign-on, let’s First Discuss what is Single Sign on?

What is Single Sign-on?

As the name suggests, Single-Sign-On Server is set of services (Software) which enables login to Application once which will allow you to login to Partner Applications with no need to login again. Let’s assume; I have configured single SSO Server for Portal, E-Business Suite, Collaboration Suite plus some other applications. Now if I login to any one of them & after that if I wish to login to other applications, I should be able to login without supplying passwords again.

Oracle E-Business Suite single sign-on integrations allow for seamless authentication to multiple systems with one user id and password. It supports deployments with third-party LDAP systems as well as third-party single sign-on systems. For Additional Information on Single Sign-On (SSO), like, why it’s used, advantages of using it, what all different type of applications can use SSO including technical details of SSO, Click Here

Overview of Single Sign-On Integration Options for Oracle E-Business Suite

Oracle has two single sign-on solutions;

A). Oracle Access Manager

B). Oracle Single Sign-On Server (OSSO)

Oracle Access Manager is the preferred solution and forms the basis of Oracle Fusion Middleware 11g. Oracle Single Sign-on Server (OSSO) is no longer being actively developed, and will not be ported to Oracle WebLogic Server.

Architecturally, the single sign-on solutions with Oracle Access Manager or Oracle Single Sign-on are very similar. Both solutions authenticate a user by verifying credentials against a user directory. The user directory service for both solutions is Oracle Internet Directory. Oracle Internet Directory and Oracle E-Business Suite user information in FND_USER are synchronized by synchronization events raised by the Workflow-based Business Event System.

Let’s Discuss these two Single Sign solution in detail here:

1.How the Oracle Access Manager Integration Works

Uses the WebGate agent, in conjunction with Oracle E-Business Suite AccessGate
Uses the mod_osso agent and is only for users upgrading from Oracle Single Sign-On Server 10gR3.

1.1 Oracle E-Business Suite Single Sign-On integration using Oracle Access Manager with WebGate and Oracle E-Business Suite AccessGate

Oracle Access Manager WebGate is a component of Oracle Access Manager that intercepts HTTP requests and redirects them to the Oracle Access Manager server to determine if and how the resources are allowed to be accessed and to authenticate the current user if authentication is required. If Oracle Access Manager is already deployed in the environment, an existing WebGate can be configured for this purpose.

Note: This Method is the most robust set of features for SSO.

According to the above figure,

An unauthenticated user attempts to access a protected Oracle E-Business Suite resource, the user is directed to the Oracle E-Business Suite AccessGate application.
Oracle E-Business Suite Access Gate is protected by the Oracle Access Manager server, so the authentication request is rerouted to a separate HTTP Server on which a WebGate is installed.
Once a user is initially authenticated by Oracle Access Manager, the request for a resource – along with the credentials returned by the Oracle Access Manager server – are picked up by Oracle E-Business Suite AccessGate.
In the end, if the Access Server credentials are valid, this application connects to the Oracle E-Business Suite database in order to link the Oracle Directory Services user, if it fails then User is Redirected to the Original URL

1.2 Oracle E-Business Suite Single Sign-On integration using Oracle Access Manager with mod_osso

Above we learned how OAM Integration works with the WebGate agent. Now we will Integrate Oracle EBS SSO using OAM with mod_osso

Steps 1 and 2. When an unauthenticated user attempts to access a protected Oracle E-Business Suite resource, the user is directed to the Oracle Access Manager 11g Server by mod_osso in the Oracle E-Business Suite OHS.

Step 3. Oracle Access Manager 11g server validates the Oracle Access Manager session (in the OAM_ID cookie, if the cookie exists), finding none (for a first time login) it displays the Oracle Access Manager SSO login page.

Step 4. The user submits their credentials and the Oracle Access Manager 11g Server validates those against Oracle Directory Services.

Step 5. Oracle Access Manager 11g Server creates the Oracle Access Manager session (OAM_ID cookie) and redirects back to /osso_login_success on the Oracle E-Business Suite tier (i.e. http(s)://<EBSHostname>.<Domain_Name>:<EBS_OHS_Port>/osso_login_success (i.e. the Success URL as defined for the Oracle Single Sign-On Agent).

Step 6. Mod_osso in the Oracle E-Business Suite OHS creates the OHS-ID cookies and sets Oracle Single Sign-On HTTP Server variables for reference by Oracle E-Business Suite.

Step 7. Oracle E-Business Suite then creates an application session for the EBS user linked to the SSO authenticated Oracle Internet Directory user.

Step 8. Finally, the user is redirected to the original URL and the requested resource is returned.

2. How the Oracle Single Sign-On Server (OSSO) Integration Works

Note: This architecture is only supported with Oracle Internet Directory as the Oracle Directory Service.

When an unauthenticated user attempts to access a protected Oracle E-Business Suite resource, the user is directed to the Oracle Single Sign-On server by mod_osso in the Oracle E-Business Suite OHS.

The Single Sign-On server looks for its cookie in the browser. If it finds none, it tries to authenticate the user with a username and password. If authentication is successful, the Single Sign-On server creates a cookie in the browser as a reminder that the user has been authenticated. If a cookie exists, the Single Sign-On server will authenticate using the cookie.

The Single Sign-On server returns the user’s encrypted information to mod_osso. Mod_osso creates its own cookie for the user in the browser and redirects the user to the requested URL.

3. Integration with Third-Party Access Management Systems and LDAP Directories

When integrating with a third-party LDAP, the third-party LDAP synchronizes user attributes with Oracle Directory Services which synchronizes user attributes with the Oracle E-Business Suite database (FND_USER).

With Oracle E-Business Suite Release 12.2, single sign-on integration is simplified. Both WebGate 11g and Oracle E-Business Suite AccessGate are automatically installed and configured on your Oracle E-Business Suite Release 12.2 application tier server node.

Oracle E-Business Suite AccessGate integrates with WebGate, which offers the most robust set of features and those who are on Oracle Single Sign-On(OSSO) should also consider upgrading to the latest certified version of Oracle Access Manager with Oracle E-Business Suite AccessGate.

In this post, we have covered the brief difference between the Hadoop Distributions i.e. Hadoop Cloudera Vs Hortonworks.

As we felt that people are getting Confused about Hadoop Cloudera & Hortonworks, Which one is better, so, we thought of writing this blog and if you go through the post completely, you will find all your doubts cleared.

If you are just starting out in BigData & Hadoop then I highly recommend you to go through these posts below, first:

Big Data Hadoop Keypoints & Things you must know to Start learning Big Data & Hadoop, check here
Big Data & Hadoop Overview, Concepts, Architecture, including Hadoop Distributed File System (HDFS), Check here

Cloudera vs Hortonworks

A number of vendors have come forward to build on Hadoop’s framework and make it enterprise-ready. The vendors have customized the open source code of Hadoop and bundled it together with user-friendly management tools and installers and packaged it with their own proprietary technologies, routine system updates, user training, and technical support. Among these Hadoop distributions, Cloudera and Hortonworks are the most popular ones.

Cloudera

Cloudera provides both open source distribution. The Cloudera Management Suite includes several sought-after features like dashboard management, wizard-based deployment, and a resource management module to simplify capacity and expansion planning.

Hortonworks

Hortonworks is comparatively a new player in the Hadoop distribution market.

Within a short span of time, Hortonworks has emerged as one of the leading vendors of Hadoop, rapidly catching up with Cloudera. The engineers of Hortonworks are also known to be contributing to most of Hadoop’s recent innovations including Yarn.

Cloudera and Hortonworks: The Similarities

Both Hortonworks and Cloudera are built upon the same core of Apache Hadoop. Therefore, both of these distributions are bound to have more similarities than differences. Let’s take a look at some of the major similarities that Cloudera and Hortonworks share:

Both offer enterprise-ready Hadoop distributions.
The distributions provided by both the vendors ensure security and stability.
Both Cloudera and Hortonworks have established communities that actively participate and help with the problems faced as well as demonstrations needed.
As Hadoop distribution providers, both Cloudera and Hortonworks have established communities that actively participate and help with the problems faced as well as demonstrations needed.
Both distributions have master-slave architecture.
Both have a shared-nothing computing framework.
Both of the vendors support MapReduce and YARN.

Cloudera vs Hortonworks – The Differences

In spite of many similarities and the same core, Cloudera and Hortonworks exhibit several differences. As we know, when it comes to choosing a vendor, differences are the ones that play a deciding role. Let’s take a look at their differentiating aspects:

Cloudera sells commercial software on top of its open source Hadoop distribution while Hortonworks is an open source purist and offers only Apache Foundation certified software.
Hortonworks’ business growth strategy focuses on embedding Hadoop into existing data platforms, while Cloudera takes the approach of a traditional software provider that profits from product sales and competes with other commercial software providers.
Hortonworks does not come with any proprietary software, therefore, uses Ambari for management, Stinger for query handling, and Apache Solr for searches of data. However, Cloudera has a proprietary management software Cloudera Manager, Cloudera Search for real-time access of products, and Impala, an SQL query handling interface.
Most importantly, Hortonworks is completely free and Cloudera provides paid services. However, it offers a free trial for 60 days.

Both Cloudera and Hortonworks are market leaders in Hadoop distributions. If Cloudera provides sophisticated paid components, Hortonworks is a purist. Both the companies are innovating the world of Hadoop and both are revolutionizing the Big Data space. Cloudera is most used in the market and if anyone learns Cloudera then they can handle Hortonworks.

Although Cloudera is the oldest player in the market, Hortonworks is rapidly catching up. So, consider all the needs of your organization, measure the pros and cons of each provider and choose your Hadoop distribution wisely.

This post covers GL Translation Process in EBS (R12). If you are new with General Ledger Process then reading this post will help you in understanding the process better.

Translation converts balances from your functional currency to a foreign currency, you can translate both actual and budget balances. If you have average balance processing enabled the system can translate average balances as well.

Translation is frequently used to prepare financial reports for consolidation into global financial statements. It is also used in highly inflationary economies to produce reports in a more stable currency.

Financial Accounting Standards Board, Statement 52, issued in December 1981, provides the guidance on booking/ consolidating the balances in foreign currencies. Monetary assets are to be translated at current exchange rates while non-monetary assets to be translated at historical rates. Simply put, the Balance Sheet items are to be translated at current rates whereas the P&L items are translated at historical/ period average rates.

Cumulative Translation Adjustment (CTA) accounts for the difference in the translated balances on P&L and Balance Sheet items arising out of using two different sets of rates.

How to achieve Translation and Cumulative Translation Adjustment entries in EBS R12?

Setup Translation options for your ledger –0

General Ledger > Setup > Accounting Setup Manager > Ledger Definitions > Currency Translation Options

General Ledger Legal Entities

Provide the Default Period End Rate Type – This is the currency exchange rate which will be used for translating the Balance sheet accounts – viz. Assets, Liabilities etc.

Provide the Default Period Average rate type – This is the currency exchange rate which will be used for translating the P&L accounts – viz. Expenses, Income etc.

Cumulative Translation Adjustment Account – This is the accounting code combination provided for CTA account. Any differences arising out of translation for Balance sheet accounts and P&L accounts owing to a difference in average rate and period end rates will be posted to this particular account.

Once the Translation Options are defined, define and run Translation.

General Ledger > Currency > Translation

Translate Balances

Provide the Ledger/ Ledger Set for which the balances have to be translated.

Balancing segment – Select All or a specific Balancing segment Values (BSV) for the Ledger for which Translation is to be defined. In a normal business case scenario, you would want to translate all your balancing segments for translation.

Balance Type – Select Actual if you want to translate actual trial balance to a foreign currency. In case you want to translate your budget to a foreign currency, select the Balance Type as Budget.

Target Currency – This is the foreign currency to which ledger balances have to be translated to. This cannot be the same as the functional currency of your ledger.

Reporting Currency is automatically defined based on the Target currency selected. Please note, the system also defines a reporting currency ledger once you run the translation.

Period – Provide the GL period of the ledger for which balances have to be translated.

In case, the balances to be translated are of a Budget type, the source and target budget and the Period End and Period average Budget Rate types provide the Budgetary balances translation options.

Click on Translate. A program will be spawned in the background. Wait for the successful completion of the program.

Once, the program was successfully completed, run the “Trial Balance – Translation” program to check the translated balances of the ledger in target currency. You may check the Ledger Definition to query the reporting currency ledger defined as a result of the translation.

The system will also create a journal entry for translation.

Accounting Entries

For simplicity perspective, consider our financial statements have balances as following in two accounts arising out of sales transactions –

Debtors 100 Dr

Sales 100 Cr

Let’s say the functional currency of the ledger is OMR. Please note, the above amounts are GL balances and may not be out of one single transaction.

Also, assume the period end exchange rate is 2.5 USD = 1 OMR. Also, the average rate for the given period is 3.0 USD = 1.0 OMR.

When the above trial balance is translated at period end, as per SFAS52, the Debtors account (a balance sheet account) will be translated at the period end rate of 2.5, whereas, the Sales account (a P&L account) will be translated at the period average rate of 3.0 USD.

Thus, the translated balances would appear as follows:

Translated Balances

Thus, a debit entry in the translated trial balance will appear in CTA account, owing to the difference in the current rate and the historical rate being used for translation of Balance sheet and P&L accounts.

In this post, we are going to look at Error Hospital in SOA 12C which is one of the new feature introduced in SOA 12C. This tells us that how to recover from faults in the error hospital and fault recovery.

Error Hospital in SOA 12C:

We are having two sections under error hospital but we will be seeing about Managing Faults in the Error Hospital for now.

Managing Faults in the Error Hospital
Creating Error Notification Rules

Managing Faults in the Error Hospital:

This describes that how to recover from faults in the error hospital, including specifying and saving fault search criteria, viewing aggregated fault statistics, performing bulk fault recoveries and bulk fault terminations in a single operation, accessing recoverable faults to perform a single fault recovery.

You can manage all faults occurring within Oracle SOA Suite and view aggregated statistics associated with faults data on the Error Hospital page.
Bulk recovery/abort operations can be scheduled from error hospital.
Robust filter and search panel available for retrieving faults similar to instance tracking.
Bulk recovery of faulted transactions from a specific service provider (HTTP Host).
Monitor the recovery.

How to Access Error Hospital in SOA 12C:

Log into EM Console (http://hostname:port number/em/)
Go to SOA Infra dashboard
Click on Error Hospital tab

We can perform the following Fault Management Tasks:

Specifying and saving fault search criteria.
Viewing aggregated fault statistics to examine fault trends.
Perform bulk fault recoveries and terminations in a single operation.
Accessing faults in the fault statistics table to perform single fault recovery operation.

Advantages of Error Hospital in SOA 12c:

A Single location for managing and recovering from all aggregated faults occurring within Oracle SOA Suite (including rejected message recovery and BPEL message recovery). Regardless of the service engine or binding component in which the fault occurred. You manage faults from the Error Hospital page at the following levels.
At the SOA Infrastructure level, where all system-wide faults data is aggregated for each business flow instance.
At the individual partition level, where only faults data for the business flow instances associated with that specific partition is aggregated.
Bulk fault recovery and termination capabilities.

So, this is about the Managing Faults in the Error Hospital and all about the Error Hospital in SOA 12C (which is a new feature introduced in SOA 12C)

We cover this in one of the modules of our Oracle SOA Dev where we also cover Develop SOA Composite, Orchestration, Managing and Monitoring Composite Applications, Fault Handling, DVM & MDS, JCA Adapters, Mediator, Business Rule Component and much more interesting and latest features in SOA 12C.

In this post, we are going to cover some important features of Exadata. This post is for beginners who are just starting to learn Exadata and covers some of the very basic questions like Exadata Administration, Cellcli commands, Networking Topology, Flash cache etc.

If you are new to Exadata, then I would highly recommend you to go through our previous post on Exadata Overview & Architecture

What are you supposed to do in Exadata Administration?

Here is the day to day tasks performed by an Exadata Administrator:

Maintain Database, RAC and ASM Instances:
Backup and Restore
Hardware Maintenance
Exadata Storage Server Administration
Exadata Health Check
Exadata Features
Exadata Patching

Some important Storage Level Commands:

Cellcli: To manage Exadata Cell Storage.
List Cell: List the cell status.
List Lun: To list all the physical drive and flash drives
List Cell Detail: List the cell status with all attributes.
List Celldisk: List all the cell disk.
List Celldisk Detail: List all the cell disk with detailed information.
List Flash Cache: To list the configured flash cache.
List Flashlog: To list the configured flash log.
List Grid disk: To list the grid disks.
List Iorm : To list the iorm plan .
List threshold: To list the threshold limit.

What is Cell Offloading?

The storage in the Exadata Database Machine is not just dumb storage. The storage cells are intelligent enough to process some workload inside them, saving the database nodes from that work. This process is referred to as cell offloading.

What is Smart Scan?

Smart Scan is a subset of Cell Offload Processing and is perhaps the feature that is most highly associated with Exadata. Smart Scan allows Oracle databases to push query information down to the storage level, specifically: Filtration (predicate information)

Networking Topology in Exadata

Oracle Exadata Database Machine includes database servers, Exadata Storage Servers, as well as equipment to connect the servers to your network. The network connections allow the servers to be administered remotely, and clients to connect to the database servers.

Leaf and Spine switches are used for networking

If you want to know more about Exadata network (click here)

Flash cache in Exadata

The flash cache is a hardware component configured in the Exadata storage cell server which delivers high performance in read and write operations.

Who is DMA?

DMA stands for Database machine Administrator. The single role that performs the management of Exadata is known as Database Machine Administrator. A person is responsible for managing Compute Nodes, Storage, and Networking of Exadata Machine.

This post is from our Exadata Training, in which we cover Exadata Overview & Architecture, Exadata Storage Server Configuration, Resource Management, Optimizing Database Performance & much more.

This Blog Covers, New Features/Changes of Oracle Identity and Access Management in 12cPS3. If you already know and Familiar with 11g Oracle Identity & Access Management Products; then It’s going to be very useful and you will receive so much new information about new changes in 12c

If you want to know more about IDM 12c Installation, RCU Schema & Configure Domain then Click here for Part1 and Part2

In this video, we are covering New Feature/Changes for Oracle Identity Management 12c PS3 (12.2.1.3.0)

First, we have explained in Oracle Identity Management (IDM) what products included and not included in 12c and then we move to Oracle Identity Governance (OIG 12c), Oracle Access Management (OAM 12c), Oracle Unified Directory (OUD 12c), Oracle Internet Directory (OID 12c).

Oracle Identity Management 12cPS3 included Four products which are

Oracle Identity Governance (OIG)
Oracle Access Management (OAM)
Oracle Internet Directory (OID)
Oracle Unified Directory (OUD)

Some products which are not included in Identity Management as Oracle Virtual Directory and Oracle Directory Service EE now they have been Migrated with OUD also OPAM, OAAM, ESSO & OES no more supportable in IDM 12c. If you want to get more details about what happened to these products then in the video we have mentioned my oracle support (MOS) Note for detailed knowledge.

In general changes, Identity Management Installation & Configuration is much simplified in 12c version.

RCU: No need to deploy separately, and is inbuilt and can be run from ORACLE_HOME. Middleware home has been changed with Oracle_home12c and Oracle_home is now become product directory. performance has improved in IDM 12c.

1. Changes in Oracle Identity Governance (OIG)/ Identity Manager (OIM)

Connector deployment is much simpler in 12c. If you are new to Connector or want to read more about connector check here

Access Policy screens have been simplified. if you don’t know about what is access policy we have covered this in our Oracle Identity Manager training in details also we have performed this on our servers.

Application On-Boarding for Application Users is much simplified. so now businees user can on board a application realted to OIM. Enhanced the Certification Process, Deployment Manager. Now pluggable database (PDB) is now supported in 12c.

To start the Pluggable database :

SQL> alter pluggable database all open;

Database altered

2. Changes in Oracle Access Management

Now as OIM/OIG Installation & Configuration has simplified and that same applicable for OAM (Oracle Access Manager) too. Most important Upgrade has simplified from 11g to 12C compared to used to be 10g to 11g.

Coherence coupling is no more supportable and it has been replaced with database cache and servers are now stateless.

MDC setup has simplified. it also includes OAuth. Security has been enhanced.

OAM 12c supports multiple password policies for setting up varying levels of password-based complexity protection for users belonging to different groups. in OAM 12c User can use Forget password option and for now, they don’t need to do OIM integration with OAM for the password changed.

Things which OAM Does Not support in 12cPS3:

Oracle Mobile Security Suite no more supportable. 10g Webgate are not supportable with OAM 12c. OAM 12c does not support IAMSuiteAgent, OAM Console now uses default OOTB Login Page and in 12c and OAM Console protected by Webgate.

3. Changes in Oracle Unified Directory & Oracle Internet Directory

Enhance the security for OUD and supporting TLS1.2 also Modern Password Scheme PBKDF2 is Supporting. When we do provisioning WLST scripting tool is supporting viaOUD. Both OUD and OID supporting Pluggable Databases (PDB) and Improved Diagnostics & Monitoring

In this video, we are going to look at Oracle Weblogic Domain Home and Server.

For those who are new, A Domain Home is a Top Level Directory for WebLogic Domain and It can be created inside or outside Middleware Home, also it is applicable for Java Components such as SOA, WebCenter etc. To know in detail about Domain Home and Server, go through the video below.

If you are a beginner and want to learn Oracle Weblogic Server Administration then check our blog post here where we covered Weblogic Domain Topology.

What is a Domain Home :

Domain Home is a Top Level Directory for WebLogic Domain
Can be created inside or outside Middleware Home
Applicable for Java Components (SOA, WebCenter etc.)

What is a Server?

A server is an instance of your WebLogic which is running on a JVM and has dedicated RAM.
There are two types of servers which are 1. Admin Server and 2. Managed Server
These Servers are Configured to host applications and resources such as WebApps, Enterprise App, WebServices, JMS, JDBC, Diagnostics etc.
Each WebLogic Server instance runs in its own dedicated Java Virtual Machine (JVM) which is their runtime environment.

What is the Java Virtual Machine:

JVM is designed to optimize itself. However, it also provides some startup options to make small changes. There are default values for its memory and garbage collection.
Each JVM has its own memory segment called Heap Memory which is the storage for Java Objects.
Every Admin Server in any domain executes within a JVM. The same also applies to Managed Servers.
WebLogic Server can be used for a wide variety of applications and services which uses the same runtime environment and resources.

So this is all in nutshell about Oracle Weblogic Domain Home and Server. Please go through the video to know in detail.

We cover this in one of the modules of our Oracle WebLogic Training, where we also cover Architecture, File System, JDBC, JMS, HA, Clustering, Security, Patching, Upgrade, Backup, and Recovery etc.

This post covers Questions & Answers asked by trainees in our Big Data Hadoop Administration Webinar in which we have covered Introduction of Big Data, What Is Big Data & 4 V’s, Big Data Use Cases, Big Data Types: Structure, Un-Structured & Semi-Structured and much more.

We recently had a Masterclass on Big Data Hadoop Administration covering What, Why & How in that webinar there were a lot of questions. Most of these questions were answered in Webinar however not all questions were covered because of time. We’ll be adding these questions over a period of time in Private Facebook Group for BigData & Hadoop and will also post these questions with answer in our blog.

These are the few questions, which we feel is common to everyone, so we have chosen these question asked by the attendees during the webinar.

Q. According to the market, Which tools are important in Hadoop?

Ans-> As Hadoop has multiple tools for Data Crunching lets deep dive into few of them.

Hadoop Distributed File System: The Hadoop Distributed File System (HDFS) is designed to store very large data sets reliably, and to stream those data sets at high bandwidth to user applications.

HBase: HBase is a column-oriented database management system that runs on top of HDFS. It is well suited for sparse data sets, which are common in many big data use cases

HIVE: The Apache Hive data warehouse software facilitates querying and managing large datasets residing in distributed storage. Hive provides a mechanism to project structure onto this data and query the data using a SQL-like language called HiveQL

Sqoop: Sqoop is a tool designed to transfer data between Hadoop and relational databases

Pig: Pig is a platform for analyzing large data sets that consists of a high-level language for expressing data analysis programs, coupled with infrastructure for evaluating these programs

ZooKeeper: ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services

NOSQL: Next Generation Databases mostly addressing some of the points: being non-relational, distributed, open-source and horizontally scalable. The original intention has been modern web-scale databases.

There are other tools as well but these are one of the important ones.

Q. I am working as Linux admin, I would like to know about Hadoop admin and I want to shift into Hadoop admin?

It is a very good choice for a Linux admin to go for Big Data administration.
Hadoop is a popular framework for handling Big data and it is the distributed computing framework for handling Big data.
There are a few skills that are required to become a good Hadoop administrator.
Since you already know Linux it will be easy for you to understand the concepts:
General operational expertise such as good troubleshooting skills, understanding of system’s capacity, bottlenecks, basics of memory, CPU, OS, storage, and networks
Should have very good knowledge of Unix based File System
Knowledge of Networking (since its distributed framework)
Thorough understanding of when to scale and how to scale
Deep Understanding of Hadoop architecture
When it comes to coding Hadoop admin will not be writing any Java MapReduce programs. But he should have knowledge of JVM and its capabilities since all the jobs in Hadoop runs on JVM.
Hadoop stack has many tools like Pig, Hive, HBase, Spark, ZooKeeper, Oozie and many more. You should have an architectural understanding of all these tools and configure them to work with Hadoop.

These are one of the few questions which were asked during our webinar on Big Data Hadoop Administration covering What, Why & How. If you have any question related to Big Data, you can either ask by commenting on the blog or just write back to us at contact@k21academy.com.

In this post, we are going to cover about Automatic Offset Accounting for Accounts Payables (AP).

For those who are new to this term; When an AP invoice is entered, there may be multiple expense/ distribution accounts and the corresponding liability account generally booked is the default account picked from the Supplier site or the one defaulted at Invoice header level.

However, there may be scenarios where a business entity is using the same Operating Unit to make purchases against multiple balancing segments. In such cases, it would be imperative to have different liability accounts booked against each of the different distribution accounts.

For example, consider an AP Invoice with a default liability account and two different distribution accounts.

Distribution 1 – BSV1.Expense Account1.Cost Center1.Future1 Dr 100

Distribution 2 – BSV2.Expense Account2.Cost Center2.Future1 Dr 150

Liability Acc – BSV3.Liability Account1.Cost Center3.Future3 Cr 250

Here, note that we have different charge accounts distributions and a single liability account for the invoice.

In normal cases, without any additional setup, the invoice will have entries posted against different Balancing Segment Values (BSV). However, for EBS implementations where a single entity may use multiple balancing segments, the requirement may be to post different liability accounts automatically based on the different distribution accounts.

Standard Oracle EBS provides the Automatic Offset Functionality to split the liability accounts for the invoice based on the different distribution accounts.

Setup Navigation – Payables > Setup > Options > Payables Options

Accounting options By default, the value defined here is None, meaning Offset accounting is disabled.

Choosing the “Balancing” option would mean that the default liability account will be used with balancing segment values changed as per the distribution accounts.

In the example taken earlier for our invoice, the system will post the accounting entries as –

Distribution 1 – BSV1.Expense Account1.Cost Center1.Future1 Dr 100

Distribution 2 – BSV2.Expense Account2.Cost Center2.Future1 Dr 150

Liability Acc 1 – BSV1.Liability Account1.Cost Center3.Future3 Cr 100

Liability Acc 2 – BSV2.Liability Account1.Cost Center3.Future3 Cr 150

Choosing the “Account” option would mean that only the natural account will be used from the default liability account at invoice header level and all the segments will be copied from the invoice distributions.

In the example taken earlier for our invoice, the system will post the accounting entries as –

Distribution 1 – BSV1.Expense Account1.Cost Center1.Future1 Dr 100

Distribution 2 – BSV2.Expense Account2.Cost Center2.Future1 Dr 150

Liability Acc 1 – BSV1.Liability Account1.Cost Center1.Future1 Cr 100

Liability Acc 2 – BSV2.Liability Account1.Cost Center2.Future1 Cr 150

Please note that the changes will not be reflected on the invoice screen. The changes will be seen once the invoice is accounted for and posted and will be visible in GL journals/ View Accounting for the invoice.

This Post Covers FREE Video on Deploying EBS Webgate in DMZ, Multiple AppTier & RAC in Oracle EBS R12.2-OAM/OID/OUD Integration for Single Sign-On (SSO).

In this Video, we are covering EBS (R12)-OAM/OID Integration for SSO with Multiple WebTier, RAC Database & WebTierin DMZ.

Below is one of the slides from our Training showing Configure Load Balancer in Oracle E-Business Suite that is part of Integration. If you want to read more about configuring Load Balancer Click Here

In this Video, we will look at how to configure multiple EBS Environment like Test, DEV, UAT or pre-production etc???

There are three Options from which we can Configure Multiple EBS Environment as given below:

1. EBS with Multiple Web Tier OAM Integration
2. EBS with RAC Database OAM/OID Integration
3. EBS Web Tier in DMZ Integration with OAM

Option 1: EBS with Multiple Web Tier OAM Integration

In EBS with Multiple Web Tier OAM Integration Ensure EBS in multi-node works with load balancer before integrating with OAM. However, lots of company not to have one to one relation with EBS with OAM/OID. They support multiple EBS environment with one OAM/OID and this is possible and fully supported.

Deploy EBS-AccessGate on each EBS Application Tier Node

perl $AD_TOP/patch/115/bin/adProvisionEBS.pl ebs-create-oaea_resources –contextfile=$CONTEXT_FILE –deployApps=accessgate –SSOServerURL=<OAM_URL> –logfile=/tmp/deployeag.log

Register EBS with OAM

txkrun.pl –script=SetOAMReg –registeroam=yes –oamHostURL=<OAM_ADMIN_URL> –oamUserName=<OAM_ADMIN> –ldapUrl=ldap://OID_HOST:OID_PORT –oidUserName=cn=orcladmin –ldapsearchbase=U_BASE –ldapGroupSearchBase=G_BASE

Option 2: EBS with RAC Database OAM/OID Integration

RAC is Stands for Real Application Cluster, provides software for clustering and high availability in Oracle database environments. Oracle Corporation includes RAC with the Enterprise Edition, provided the nodes are clustered using Oracle Clusterware.

Few Points remember when Configure EBS with RAC Database

No Change in EBS-OAM Integration
Ensure that ‘orclAnonymousBindsFlag’ is set to ‘Allows’
EBS Database RAC Node, Enable Directory Uses via netca (on all RAC Nodes)
Register EBS Database with OID via dbca (Only from any one RAC Node)
Register EBS with OID as done in single node with option –rdbmsdn=cn=OracleContext

Option 3: EBS Web Tier in DMZ Integration with OAM

Note: Make sure the webgate you configured in EBS Application tier that configured in ECC Mode also, OAM LogoutURL should be in DCC.

Points for DMZ Integration with OAM

OAM & ODS (OID/OUD) in Intranet
EBS Apps Tier with WebGate for external must be configured in DCC
OAMLogoutURL must point to DCC Logout URL (/oamsso-bin/logout.pl)
Allow login and logout URL of DCC from URL FW in EBS

We’ll be adding these questions over a period of time in Private Facebook Group for BigData & Hadoop and will also post these questions with answer in our blog.

These are the few more questions, which we feel is common to everyone, so we have chosen these question asked by the attendees during the webinar.

This is the follow-up blog of our previous post in which we have covered remaining Q/A’s asked during the webinar

Q. What is the Role of Bigdata & Hadoop in Machine Learning & Artificial Intelligence?

Machine Learning and Big Data as such have no direct relation. Although one can say that Big Data Techniques can be used in Machine Learning. I will tell you the difference between both the fields for you to understand better. Machine Learning usually works with huge chunks of data and this where Big Data comes into the picture.

Machine learning: Machine Learning is the science of creating algorithms and program which learn on their own. Once designed, they do not need a human to become better.

Some of the common applications of machine learning include the following:

Web Search
Spam filters
Recommender systems
Ad placement
Credit scoring
Fraud detection
Stock trading
Computer vision
Drug design

Machine learning helps data science by making a provision for data analysis, data preparation and even decision making like real-time testing, online learning. Data science clubs together algorithms derived from machine learning in order to provide a solution. Data science carries out this activity by taking a lot of ideas from basic mathematics, statistics and domain expertise.

Big Data Analytics: Big Data Analytics is studying large data sets (big data) to identify hidden patterns, market trends, consumer preferences and other valuable information helping organizations to form strategic business decisions.

With the help of Big data analytics, data scientists and other analytics professionals can examine huge amounts of structured data as well as the untapped data by deploying analytics and business intelligence.

Big Data Analytics comprises specialized software and analytics systems benefiting business in many ways like

Cost efficiency: Hadoop and cloud-based analytics are big data analytics technologies are very cost effective when storing huge amounts of data. Moreover, this also helps in finding more effectual ways of doing business.
Faster decision making: Organizations can examine data immediately with superfast Hadoop and in-memory analytics. Decisions can be taken with much ease on the basis of what they have experienced.
New products and services: Big data analytics helps to easily understand consumer needs and preferences giving more power to serve customers what they want.

Q. How BigData is Evolving Now a Days? What is the Future scope?

For the last five years or so one could argue that “big data analytics”, or any of the semantic variations thereof, has been the hottest sector in the silicon valley. The Internet of Things could make a claim to that crown now, but really the most interesting thing about The Internet of Things is all the data, and so we’re right back to big data and analytics, which is a part of big data.

Data in aggregate is growing so fast that everything about how we think about data now is going to change radically in the next ten years. If you’re a software engineer or work in technology in any way, this should sound like an opportunity. Everything from hardware to networking to database technology to presentation layer is already changing rapidly to allow us more efficient access to data that will let us live and work better.

When I hear terms like big data analytics or cloud, they’re being used often enough and to describe companies small or obscure enough that they don’t really mean anything. This is a general knock against buzzwords and the nature of search engine marketing and the semantics of new technology and hype-waves in general.

But don’t let that fool you. For people who make decisions about how to allocate resources, big data analytics is one of the more important wormholes through which computing power and networking capability transform into honest to god Quality of Life” improvement that’s so significant it defies our attempts to measure it.

According to a report, the market for Data Analytics, more specifically the Business Intelligence Market is expected to grow to $20.81 Billion by 2018.

The sudden Business Intelligence growth is influenced by many factors. like,

Organisations are increasingly tapping opportunities to leverage streaming data generated by devices, to make faster, relevant and real-time decisions.
Data Analytics will include Cloud Deployments of BI and Data Analytics platforms which have the potential of reducing the cost of ownership and aid speedy deployment.
There is also a need for business users to analyze, large and complex combinations of the data source and data models. This needs to be done faster than before, in a more automated method for expanded use.

You will get to know all of this and deep-dive into each concept related to BigData & Hadoop, once you will get enrolled in our Big Data Hadoop Administration Training

This Post gives you the basic understanding of IDCS (Oracle Identity Cloud Service) & Things you should know about it.

Today, Security Practice is a crucial undertaking for any enterprise. As trust is essential for the success of the digital business, IDCS is rapidly becoming a key differentiator in the enablement of innovative digital services.

Now the next question which comes to your Mind is, What is Oracle Identity Cloud Service (IDCS)?

Oracle Identity Cloud Service provides identity management, single-sign-on (SSO) and identity governance for applications on-premise, in the cloud and mobile applications.

Any user can access the application at any time, anywhere on a device in a secure manner. Oracle IDCS integrates directly with existing directories and identity management system, making it easier for users to access applications. Providing a platform that is robust and secure, allows users to access, develop and deploy their applications.

The benefits of implementing Oracle Identity Cloud Service are; Improved Business Responsiveness, Enhanced User Productivity and Experience, Hybrid Multi-Channel Access and finally Simplified IT and Reduced Cost.

Below is a diagram which shows how Oracle Identity Cloud is held together.

IDCS

Advantages of Oracle Identity Cloud Service

Hybrid Identity

Application security for cloud and on-premises workloads
Access Certification, Audit, and Compliance for Cloud Apps using OIG (Oracle Identity Governance)

In this Post, We’ll be exploring JCS (Java Cloud Service). This post is for the beginners who have just started their journey in JCS and covers some of the very basic topics like Overview, Features, Software release & Creating JCS Instance on Cloud.

What is JAVA Cloud Service (JCS)

Oracle Java Cloud Service is a part of the platform service offerings (PaaS) in Oracle Cloud. Powered by Oracle WebLogic Server, it provides a platform on top of Oracle’s enterprise-grade cloud infrastructure for developing and deploying new or existing Java EE applications. All Oracle Java Cloud Service instances are integrated with one or more database deployments in Oracle Database Cloud Service. You can also use Oracle Database Exadata Cloud Service.

Software Releases

The Oracle Latest WebLogic Server software releases and versions supported at the service levels

Oracle WebLogic Server 12c (12.2.1) with Java Required Files 12c (12.2.1) This is the foundation for Oracle Fusion Middleware 12c (12.2.1). WebLogic Server 12c (12.2.1) is Java EE 7 compatible.

Feature/Use of Java Cloud Service(JCS)

With the use of Oracle Java Cloud Service rapidly provision an application environment with Oracle WebLogic Server as the application container, Oracle Coherence as a caching and data grid tier, and Oracle Traffic Director as the software load balancer—all on top of infrastructure provided by Oracle Compute Cloud Service.
All nodes in your WebLogic Server domain and cluster are started automatically
you can begin to deploy applications to your service instance. You can quickly go from zero to HelloWorld!

JCS builds on three other Oracle Public Cloud Services that we need to be aware of:

DBaaS (Database)
Compute Cloud Service
Storage Cloud Service.

Prerequisites

If you use a QuickStart template to create an Oracle Java Cloud Service instance, you do not need to fulfill any prerequisites. But in order to create a custom service instance, you must first provision an Oracle Database Cloud Service deployment. You may also need to satisfy additional prerequisites depending on your requirements.

Various Methods for Creating Oracle JCS Instances

There are several ways in which you can create an Oracle Java Cloud Service instance, depending on your requirements and experience level.

1. using a QuickStart template: The fastest and easiest way to create a service instance is by using a QuickStart template. This method also creates the required Oracle Database Cloud Service instance as well.

2. Oracle Cloud Infrastructure Compute Classic region: Create a service instance on an Oracle Cloud Infrastructure Compute Classic region that meets your precise specifications, and associate it with an existing Oracle Database Cloud Service instance.

3. Oracle Cloud Infrastructure region: In this, Each region has multiple isolated availability domains, with separate power and cooling. The availability of domains within a region are interconnected using a low-latency network. When creating an instance, you can select the availability domain that the instance should be placed in.

In this Post, we are using QuickStart template to Create Java Cloud Service Instance

This post covers Key differences between Exadata Database Machine & Oracle Database Appliance. This post is for beginners as well as for experience holders such as DBA’s who are just starting to learn Exadata and we have dedicated course for Exadata where we cover everything about Exadata, which will make you from zero to hero in Oracle Exadata Database Machine (click here)

If you are new to Exadata then I would highly recommend you to go through our previous posts on Exadata.

Exadata Overview & Architecture (Click Here)
Important Features of Exadata(Click Here)

Overview of Oracle Exadata Database Machine

The Oracle Exadata Database Machine is an easy to deploy solution for hosting the Oracle Database that delivers the highest levels of database performance available. The Exadata Database Machine is a “cloud in a box” composed of database servers, Oracle Exadata Storage Servers, an InfiniBand fabric for storage networking and all the other components required to host an Oracle Database.

Overview of Oracle Database Appliance

A database appliance is a pre-configured, balanced set of hardware (servers, memory, storage, and I/O channels), software (operating system, database management system [DBMS] and management software), service, and support. It is sold as a unit with built-in redundancy for high availability and positioned as a platform for DBMS used in online transaction processing (OLTP) and/or data warehousing.

Difference Between Exadata and Oracle Database Appliance

Exadata is a pre-configured combination of hardware and software that provides an infrastructure for running Oracle Database. It consists of a database layer and a storage layer connected through an InfiniBand network. The database layer consists of Sun servers and runs Oracle 11gR2 software and normally Oracle RAC is deployed on database node. The database layer uses ASM to map to the storage layer. The storage layer also consists of Sun Servers and runs Oracle Storage server software. Exadata’s exclusive features are smart scan, Hybrid Columnar Compression, and Storage Indexes.
Oracle Unbreakable Database Appliance (ODA) is a completely integrated highly available (HA) database system in a single box. OUDA is an appliance and it contains storage, servers, Operating System, and web-based monitoring tool (database control) within one box. It provides a ready-to-use, clustered database solution that includes both hardware and software optimized to work together.
Exadata is not an appliance, ODA is. A server appliance is a computer for specific tasks, such as handling email or storing data, and a database appliance is just that; a computer to handle database. It is meant to be bought, brought into the data center, plugged in, data loaded, and then gave access to the user, as you would do with any other appliance. But courtesy to Oracle’s inherent architecture, you can customize, tweak and tune the appliance parameter according to your requirement.
ODA is geared towards small and medium-sized business, whereas Exadata is for the big guns.

In this post, we will look into Enterprise Manager Partition in Oracle SOA Suite 12c/11g. Partition is a mechanism of segregating your composites based on the types of functionalities it performs. It also helps you to deploy two or more composites with the same name and same revision id on the same server.

It comes very handy when we need to manage a large number of composites by categorizing composites on the kind of task it performs and we can have one partition for each category.

Below are the steps to create partition would help you to understand things better:

Make sure your Enterprise Manager Fusion Middleware control console is up and running.
URL for em console like http://[hostname]:/[port no of admin server]:/em as in our case we are taking http://1705soa30.k21technologies.com:7001/em

Give the credentials which you have configured while creating the Domain.

Expand Farm_SOA_Domain and SOA and Search for “SOA_Infra (SOA_Server) node.

On the Righthand side select the “SOA-infrastructure” related menu and select the menu “Manage Partitions”

Under Manage Partition Click On “Create New Partition”

Give the partition name as per your requirement as “k21SoaPartition”. Click On Create.

Find all the existing partitions in SOA infra. By default, we have “default partition” which is an inbuilt domain. Our k21SoaPartition got created Successfully.

This post covers the Types of Oracle Cloud Accounts. As we are seeing people getting confused between different types of Oracle Cloud Account, so we thought of writing this blog and clear their doubts.

When you sign in to your Oracle Cloud account, you have access to two different types of cloud accounts: traditional cloud accounts (also known as cloud service accounts) and cloud accounts with Oracle Identity Cloud Service.

Oracle Cloud Account type

Most Oracle Cloud services are designed to run in an Oracle Cloud account with Oracle Identity Cloud Service. This means that the service uses Oracle Identity Cloud Service to manage users and to control access to the service. However, some Oracle Cloud services still rely on Oracle Identity and Access Management for the same purposes.

If you sign up for Oracle’s Free Credit Promotion or a new paid Oracle Cloud account, then you will likely have access to both types of cloud accounts.

There are two ways to switch between the different accounts:

Use a URL to sign in to each type of account. This URL is in the welcome email you receive when you sign up for Oracle Cloud.
Use the Identity Domain drop-down menu in the My Services dashboard. Note that there are restrictions when you switch between cloud accounts using this option.

A list of the services that require you to have a traditional cloud account is in the second email you receive when services are provisioned in your cloud account.

The table below summarizes the differences in the dashboard view and service access when you switch accounts.

Cloud Account with Identity Cloud Service	Traditional Cloud Account (Identity Domain)
View all services in this account and the traditional account.	View services in this account only, not the ones in the Cloud Account with Identity Cloud Service.
Limited access to the services in the traditional account. You must switch to traditional account to create service instances.	No access to services in Cloud Account with Identity Cloud Service.

In this post, we are going to cover creating GoldenGate Global User in Multitenant Architecture. Oracle Database 12c introduced the Multitenant Architecture for Oracle databases. This allows for multiple pluggable databases to exist within the same container database.

GoldenGate Multitenant Architecture

If you are new to Oracle GoldenGate then check our previous posts about Oracle GoldenGate 12c Overview & Components. And GoldenGate 12c (12.3.0.1) New Features/Changes

If you want to install Goldengate 12c then go through our post here Oracle GoldenGate 12c Download & Installation and for troubleshooting go through Oracle GoldenGate 12c: Troubleshooting using LogDump Utility

1. Create Global User & Grant DBA Role

We need to create the Global user in Multitenant architecture for Goldengate replication. In order to segregate the tablespace for golden gate user, it is advisable to create a separate tablespace. The tablespace will be required in both containers as well as in all pluggable databases.

Note: gg_tblsp needs to be created in pluggable as well as container databases.

a) In container database:

SQL> create tablespace ggs_tblsp datafile ‘/u01/app/oracle/oradata/OGGDB1/datafile/gg_cdb.dbf’ size 2G;

b) In Pluggable database:

SQL> alter session set container=PDB1;

SQL> create tablespace ggs_tblsp datafile ‘/u01/app/oracle/oradata/OGGDB1/datafile/gg_pdb1.dbf’ size 2G;

Note: Same needs to be done individually in all PDBs if there are multiple Pluggable.

2. Create a user in container database with prefix c##.

Note: In 12c this user is common to all the pluggable present. (In 12c all common users and roles are created with prefix c##)

SQL> create user c##ggadmin identified by Welcome1 default tablespace ggs_tblsp;

SQL> grant dba to welcome1 container=all;

Note if a tablespace is not created in any of the pluggable or container, you will hit the error tablespace doesn’t exist. So below is the workaround:

Create the tablespace in all existing containers and Pluggable
Or create the user without defining any tablespace. However, this is not recommended in Prod environment.
