Scenarios When Control Files Are Lost ( given in oracle Doc).
Scenario -1
Status of Online Redo -Available
Status of Datafiles - Backup
Restore Procedure-
Backup Restore a backup control file, perform complete recovery, and then open RESETLOGS.
Scenario -2
Status of Online Redo - Unavailable
Status of Datafiles - Backup
Restore Procedure - Restore a backup control file, perform incomplete recovery, and then open RESETLOGS.
I am practising all the scenarios in backups and recovery.
Could someone please correct me if anything wrong in the following steps for the above mentioned scenarios.
Database is running in archivelog mode and closed.
Scenario -1
(This is complete recovery)
1) restore only lost/damged datafiles and the control file from backup.
2) startup mount;
3) recover database using backup control file
4) apply all the necessary archive logs
5) alter database open resetlogs.
Scenario -2
(This is incomplete recovery)
1) restore all the datafiles and the control file from backup.
2) startup mount
3) recover database using backup control file until cancel
4) apply all the necessary archive logs and redo logs and type cancel when the oracle promts for the log file which is not avilable.
5) alter database open resetlogs.
Thank you
Suresh

Thank you for your reply.
I am not using RMAN.
I just want someone to check the steps which i have written to recover the control file based on the status of online redologs.
All these scenarios are given in oracle doc. i need to know the correct steps to perform.
Suresh.

I'm surprised there is an Oracle documentation that talked about recovery scenario without giving how to recover.
Post where you found that.
Generally speaking, ALWAYS post the link and/or the book/chapter/section where you quote something from.
Regards
Michel
