Comment on RMAN configuration with Tivoli Data Protection for Oracle (TDPO) by Yannick

Hi Lodh,

Good and tricky question !

If no controlfile autobackup and a recovery catalog then connect to recovery catalog and issue:

Startup force nomount
restore controlfile;
alter database mount;
recover database;
Alter database open resetlogs;

If no controlfile autobackup and no recovery catalog then it’s even complex because you would need to play with CATALOG command and restore few backupset from tape to local database server disk to catalog them… Not a safe situation for sure !

Reading further Oracle documentation I now think controlfile autobackup is a good idea and do not use that much disk/tape space, so modifying my script: happy ?

Please note that even with controlfile autobackup and no FRA, restore process is not that simple…

Hi Yannick,

I find the blog truly useful for TDP backup configuration. Its a small guide to start with TDP backup in few minutes.

Hello Yannick

One thing which confuses me is that – You have switched off controlfile auto backu, then how will you restore your control files using TDPO & RMAN. The only way is to create new controlfiles, mount the DB and then go for rman restore. What say ?

I tried restoring control file but it gives me the below message :-
– RMAN-06563: control file or SPFILE must be restored using FROM AUTOBACKUP

So i think we need to have a separate controlfile backup on disk somewhere ……

the second method is more useful,because no reboot of db is needed..

I meet the same situation of locking account,it’s quite noisy…
