Hi max,

Do you have the backup log? You will find in it the backup piece
corresponding to your controlfile.

Hi Hemanth,

That is what i was going to do, but for whatever reason i cant find my
controlfile backup piece. I thought it would be in a format like below
from my autoback format(%d_ctl_%F')...

SID_ctl_c-4868747647-20151103-08

but all i see in my backup directory(speical backup directory) are in
this format "%d_TAG_NAME_%s_%U", so its hard to identify which one is my
control file backup peiece...

You’d have to start with RESTORE CONTROLFILE FROM

If you don’t know which backup piece it is you could discern it from
the piecename (for an autobackup) and size.

Hello list,



this is on 11.2.0.4 with "No Recovery catalog" in place. I used the
below command to create a special backup, so that it is not deleted by
delete backup script(as our retention policy is set to 7 days).



BACKUP database FILESPERSET 1 FORMAT
'/path/to/backup/file/%d_TAG_NAME_%s_%U' tag 'TAG_NAME' keep until time
'sysdate+50';



Now I want to restore using this specific backup from this TAG. I know
if i have recover catalog in place, i can connect to that, and do restore
controlfile from tag='TAG_NAME' but how do i do the same when no recovery
catalog.



Lets says i lost everything(datafiles, redo logs, control files,
spfile)...from what i under about the "keep until" clause it should
encapsulate everything(datafile, controlfile, spfile if its in place)... so
now if i want to restore, as my control file is gone, how do i restore from
these tags ?



I tried something like below but that does not seem to work...



run {

set controlfile autobackup format for device type disk to
'/path/to/backup/file/%d_TAG_NAME_%s_%p_%t_%U';

restore controlfile from autobackup validate;

}





run {

set controlfile autobackup format for device type disk to
'/path/to/backup/file/%d_TAG_NAME_%s_%p_%t_%U';

restore controlfile from tag='TAG_NAME';

}



here are the RMAN config(show all) that i am using..



CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;

CONFIGURE DEFAULT DEVICE TYPE TO DISK;

CONFIGURE CONTROLFILE AUTOBACKUP ON;

CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO
'/path/to/backup/file/%d_ctl_%F';

CONFIGURE DEVICE TYPE DISK PARALLELISM 2 BACKUP TYPE TO BACKUPSET;

CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT
'/path/to/backup/file/%d_%s_%p_%t_%U';
