Install Oracle Database on Linux

I had to Install Oracle Identity Manager for SSO which needs Oracle Database for MetaData Repository Storage.

I followed the Below steps to Install the Database.

Version used: Oracle

OS Used : Enterprise Linux Enterprise Linux Server release 5.2 (Carthage)

Created one OS user : oracle .

Created two OS group : dba, oinstall.

Added the OS user : Oracle to Group dba and oinstall.

On linux :

id oracle

uid=502(oracle) gid=501(dba) groups=501(dba),502(oinstall)

Now I have the software in the directory :


cd /u01/app/soft/


Specify the Installation Directories :

Oracle Base = /u01/app/oracle

Oracle Software Install location : /u01/app/oracle/product/1121

Here “dba” is the group from OS.



[root@wbidm 11201]# ./

Running Oracle 11g script…

 The following environment variables are set as:

    ORACLE_OWNER= oracle

    ORACLE_HOME=  /u01/app/oracle/product/11201


Now the Database Installation is Successful

Now we need to setup the environment variable for the Oracle Software .

As this is Redhat Linux, we will be setting the environment in .bash_profile file located in /home/oracle dir ( oracle is the OS userid ).

Below are the details to be added in the .bash_profile file :

wbidmdb = This is the database service name that we will create here.


export PATH
export ORACLE_BASE=/u01/app/oracle
export ORACLE_SID=wbidmdb
export ORACLE_HOME=/u01/app/oracle/product/11201
export PATH=$PATH:$ORACLE_HOME/bin:/usr/java/jdk1.6.0_26/bin:.

export PATH


After editing the above environment variable parameter , logout from the linux terminal and log-in back.

Now below are the steps to create the DATABASE ( WBIDMDB) using the dbca command:
