How to change Oracle user ORACLE_HOME

We have to change our ora user $ORACLE_HOME from /u02/oracle to /u02/oracle/11.1.0. Here are steps which I have followed and done this.

1. Run adpreclone.pl on dbtier as oracle user

perl adpreclone.pl dbTier

2. Shutdown down database and listener.

3. mv all files from /u02/oracle to /u02/oracle/11.1.0

4. run adcfgclone.pl for binaries only to avoid db creation

perl adcfgclone.pl dbTechStack

It will ask you certain info, please provide it accordingly.

5. update profiles from $OH/appsutil/install/

sqlplus "/ as sysdba" @adupdlib.sql so

6. change directory to $OH/appsutil/clone/bin

perl adcfgclone.pl dbconfig $OH/appsutil/context_file.xml

7. run autoconfig on appstiers too.

8. Start all services and check.

Happy Troubleshooting !!!
