Before I dig into the upgrade stuff this is what i did before upgrading.
1. Created DB11g instance in – 11.2.0.2 with ORACLE_HOME=/u02/app/oracle/product/11.2.0.2/db_1 and ORACLE_BASE=/u02/app/oracle.
2. Installed 11.2.0.3 Software with ORACLE_HOME=/u01/app/oracle/product/11.2.0.3/db_1 and ORACLE_BASE= /u01/app/oracle.
So now find out the current version of the database which is DB11g and then we will go ahead with the upgrade steps.
First of all find out the current version of the database:
*************************************************************************
[oracle@OEL64 ~]$ . oraenv
ORACLE_SID = [APEX] ? DB11g
The Oracle base has been changed from /u01/app/oracle to /u02/app/oracle

Miscellaneous Warnings
**********************************************************************
WARNING: –> Your recycle bin is turned on and currently contains no objects.
…. Because it is REQUIRED that the recycle bin be empty prior to upgrading
…. and your recycle bin is turned on, you may need to execute the command:
PURGE DBA_RECYCLEBIN
…. prior to executing your upgrade to confirm the recycle bin is empty.

…. Refer to the 11g Upgrade Guide for instructions to configure Network ACLs.

**********************************************************************
Recommendations
**********************************************************************
Oracle recommends gathering dictionary statistics prior to
upgrading the database.
To gather dictionary statistics execute the following command
while connected as SYSDBA:
EXECUTE dbms_stats.gather_dictionary_stats;
**********************************************************************
Oracle recommends reviewing any defined events prior to upgrading.
To view existing non-default events execute the following commands
while connected AS SYSDBA:
Events:
SELECT (translate(value,chr(13)||chr(10),’ ‘)) FROM sys.v$parameter2
WHERE UPPER(name) =’EVENT’ AND isdefault=’FALSE’
Trace Events:
SELECT (translate(value,chr(13)||chr(10),’ ‘)) from sys.v$parameter2
WHERE UPPER(name) = ‘_TRACE_EVENTS’ AND isdefault=’FALSE’
Changes will need to be made in the init.ora or spfile.

******************************************************************************************************
Now we will go ahead with the upgrade step. Set the ORACLE_HOME to 11.2.0.3 and execute dbua utility.
1. Set the ORACLE_HOME to 11.2.0.3.
2. Set the PATH to the new ORACLE_HOME (else it will still pick up the old one.)
[oracle@OEL64 ~]$ echo $ORACLE_HOME
/u01/app/oracle/product/11.2.0.3/db_1
[oracle@OEL64 ~]$
[oracle@OEL64 ~]$ which dbua
/u01/app/oracle/product/11.2.0.3/db_1/bin/dbua
[oracle@OEL64 ~]$
[oracle@OEL64 ~]$ dbua
Press Next.
Select the Database which you are planning to upgrade and Press Next.
It will fetch the information and print the same warning which we got in pre-upgrade utility.
Press Yes. If the shown warning is going to hamper your database later on, then take care of them before upgrade.
You can select the Backup Database option if you want to rollback later on if in case anything happens (i have not tried this though yet). Press next.
No Changes, press Next.
Specify the FRA if in case you want to change to some other place. Press Next.
Press Finish.
Press OK.
Check out the upgrade result.
So as per the above result this database have the new SPFILE Created in new ORACLE_HOME of 11.2.0.3.
Database upgrade has been completed successfully, and the database is ready to use.
The following document describes important behavioral changes from previous database releases:
/u01/app/oracle/product/11.2.0.3/db_1/assistants/dbua/doc/DefaultBehaviorChanges.html
Note, the db has been restarted for you. Change the .bash_profile and /etc/oratab file if not already changed.
Check the version now:
SQL> select * from v$version;
