RMAN with READ-ONLY tablespace

edited May 23, 2012 10:23AM in Database Backup and Recovery (MOSC) 2 commentsAnswered
Hi there:
How should I backup my database after I have made several of my tablespaces READ-ONLY, should I do option 1 or option 2 below:

Option 1:

1. Make tabelspaces read-only
2. Using RMAN - backup only READ-ONLY tablespaces
3. Do a Full RMAN database backup skipping READ-ONLY tablespaces

Option 2:

1. Make tabelspaces read-only
2. Using RMAN - backup only READ-ONLY tablespaces
3. Do a Full RMAN database backup including READ-ONLY tablespaces
4. The subsequent Full RMAN database backup skipping READ-ONLY tablespaces

I have retention period set to 1.

thanks
Zahid
