Oracle Access Manager Upgrade from 11.1.2.0 to 11.1.2.3.3 - Part1

BACKUP and SOFTWARE REQUIRED:

BACKUP:

1) It is always good practice to take backup of existing binaries before starting with any major upgrade.
Please take backup of below mentioned homes. 

MW_HOME directory
Oracle Home (Oracle_IDM) directories inside Middleware Home
Domain Home directory 

Note: It is advisable to take complete backup of mountpoint (ex: /u01) on which OAM(oam_domain) is installed.

2) Please take backup of below mentioned schemas:

OAM schema(XXX_OAM)
MDS schema (XXX_MDS)
ORASDPM schema(XXX_ORASDPM)
OPSS schema(XXX_OPSS)
Audit schema (if applicable)(XXX_IAU)

3) It is advisable to take complete backup of database along with above schemas.

Note:

1. Backup the software and the database schemas at the same time. Recovering a backup of software along with a backup of the database schemas which has been taken at a different time can cause significant problems. The software and database schema backups should always be in sync.
2. For clustered installations, the OAM Middleware Home must be backed up on each clustered server.
3. Validate the backup by doing a test restore before beginning the upgrade to make sure that backup is functioning correctly as expected. 
4. There is no rollback option for the 11.1.2.3 upgrade. So only option is to revert it to backed up binaries and schema.
