How To Create Master repository in ODI 11 G(Oracle Data Integrator)

How To Create Master and Work Repository:

Step 1: Prerequisites for working with ODI:

·         ODI should be installed, for configuring ODI we need Master repository and Work repositories. These repositories can be created in two ways:

1)      First way is to create the repositories in the DB(Data Base) and then use it in the configuration, the steps for this is given in Step 2 and the

2)      Second method is to do it through RCU (Repository Creation Utility), steps for this is given in Step 3.

For Complete step 2(Create repository in the DB) we have to create user in the DB. The user can be created in Oracle  (this user can be created in any RDBMS).

Find Scripts to create users in the DB.

--------------------------------------------------------

 SCRIPT FOR CREATING ODI User

--------------------------------------------------------

CREATE USER SINGH_DEV_ODI_REPO IDENTIFIED BY DEV_ODI_REPO;

GRANT CONNECT, RESOURCE TO SINGH_DEV_ODI_REPO ;

Note: Here SINGH_DEV_ODI_REPO is a Username and

Password: DEV_ODI_REPO. We will create this username in the data base and then use this user for Creating Master Repository.

·         Execute the script in any user with SYSDBA privilege.

Important: We can create any number of Master repositories and Work Repositories

Step2:  How to Create Master Repository and Work Repository :

Open ODI Studio: StartàAll ProgramàOracleàOracle data integratoràODI studio

ODI(Oracle Data Integrator)Start Page will open

Click on File->New and below window will be opened.

Select Master Repository Creation Wizard ---then Click :Window will openàMaster Repository Creation Wizard step1 of 3:

Technology:Oracle (Select any RDBMS).

JDBC Driver:Select respective Driver that supports selected technology.

JDBC URL:enter the specific information of the system on which oracle is available.                                                      

User:<Master Repository User name> ex: SINGH_DEV_ODI_REPO

Password:<Master Repository User’s Password>Ex: DEV_ODI_REPO

DBA User:<DBA User name> Ex: User name which you user during oracle installation

DBA Password:<DBA User’s Password> Ex: password which you user during oracle installation

Test the connection, Enter the ID for master repository and click Next, this creates Master repository related tables in the Oracle user that we have used for Master repository for the first time

Oracle Warehouse Installation Basics

Oracle Warehouse Installation Basics Information:

If  you want to work on all Oracle BI Component then you must have install below software in your Local Machine.
1.ODI(Oracle Data Integrator) 11G.
2.SQL Developer.

3.Oracle 11G(if required). Oracle Data base is very heavy and not advise  to install in your machine(It Required 6 to 8 GB RAM)Always install  oracle Database on separate server,and then from your machine you can connect to oracle server.

4.Oracle 11G XE(Express Edition): ( If you feel Oracle 11G Data base is slow your system then you  can install Oracle 11g XE (express edition with limited functionality that will be fine for practice/Training Purpose). This occupies less space and it will not use more system resources.

5.OBI:Not recommended to install OBI on local system  as it occupies more space.Install OBI in Separate server

ODI(Oracle Data Integrator)

Introduction to Oracle Data Integrator:
 

1.ODI(Oracle Data Integrator) is a Widely used data integration software product.
2.ODI Provides a new design approach to Defining data transformation and integration process and provide results with faster and simpler development and maintenance.
3.ODI is based on unique E-LT architecture (Extract - Load Transform),
4.It Provides high performance for execution of data transformation and validation process and it is very cost effective.

Why to choose ODI:
•Faster and simpler development and maintenance: The declarative rules driven approach to data integration greatly reduces the learning curve of the product and increases developer productivity while facilitating ongoing maintenance.
 
•Data quality firewall: Oracle Data Integrator ensures that faulty data is automatically detected and  recycled before insertion in the target application. This is performed without the need for programming, following the data integrity rules and constraints defined both on the target application  and in Oracle Data Integrator.

•Better execution performance: traditional data integration software (ETL) is based on proprietary  engines that perform data transformations row by row, thus limiting    performance. By implementing  an E-LT architecture, based on your existing RDBMS engines and SQL, you are capable of executing data  transformations on the target server at a set-based level, giving you much higher performance.

Simpler and more efficient architecture: The E-LT architecture removes the need for an ETL Server sitting between the sources and the target server. It utilizes the source and target servers to perform complex transformations, most of which happen in batch mode when the server is not busy processing end-user queries.
•Platform Independence: Oracle Data Integrator supports all platforms, hardware and OSs with the same software.

Data Connectivity: Oracle Data Integrator supports all RDBMSs including all leading Data warehousing platforms such as Oracle, Exadata, Teradata, IBM DB2, Netezza, Sybase IQ and numerous other technologies such as flat files, ERPs, LDAP, XML.

• Cost-savings: the elimination of the ETL Server and ETL engine reduces both the initial hardware and software acquisition and maintenance costs. The reduced learning curve and increased developer productivity significantly reduce the overall labor costs of the project, as well as the cost of ongoing enhancements.
