Hello All, We are upgrading the database from version 8.1.7.3 to 8.1.7.4. What if the Upgrade fails ( I did it couple of times , but never failed for me), How to recover to previous version??
Here is what I think , please correct me and add some more points here. 1. Backup the $ORACLE_HOME for version 8.1.7.3 2. Take backup of SYSTEM tablespace ( after the clean shutdown of the DB and just before Upgrade ) 3. Make all other tablespaces READ ONLY ( except system / TEMP ( we use tempfiles )/ RBS ) When we running catalog.sql and catproc.sql In case of any failure while patching , can we start the DB after restoring $ORACLE_HOME and System tablespace from backups ?? Can some one share your experiences , also it would be beneficial for me , if someone send me a upgrade checklist / process offline THANKS !!
