Instant recovery from replicas containing the control file

During an instant recovery from a replica that contains the control file, the current
control file and, possibly, online redo logs get overwritten. Therefore, before you
start the session, copy the current control file and online redo logs to a safe location
to be able to do a database recovery afterwards.
A replica contains the control file if it is created in any of the following sessions:
• Online ZDB session with the omnirc variable ZDB_ORA_INCLUDE_CF_OLF set
to 1
• Online SAP compliant ZDB session
• Offline ZDB session (any configuration)
NOTE:
An offline ZDB session also contains online redo logs. You can use such a session to
restore the SAP R/3 database to a point in time at which the backup was performed. In
this case, you do not need to follow the steps below.
To restore and recover the database:
1. Copy the current control files and online redo logs to a safe location.
2. Perform instant recovery (without database recovery). Use the Data Protector
GUI or CLI.
3. Copy the current control files and online redo logs back to their original location.
4. Mount the target database.
