Database Backup-Restore in patched environment

edited Jun 22, 2016 5:00AM in Database Backup and Recovery (MOSC) 2 commentsAnswered

Hi, I need to know how the pros have been doing OR what is recommended approach of Oracle regarding that.

Here is my scenario: I have (Windows) database server with 5 instances running of version 11.2.0.3 in time-0. At time-1 I have applied patch 1a to the software base and to the instances. Now all dbs are version 11.2.0.3 a1. In time-2 I apply patch b2 which changes the level to 11.2.0.3 b2.

all backups are done via RMAN:

Questions:

1. Can database from tim-0 be restored under Oracle home in time-1 (patch a1) or time-2 (patch b2)? My understanding is the database dictionary MUST be same version as software base.

Howdy, Stranger!
