Recovery with backup controlfile bad!
I think that after you have applied the last redo log you have to cancel the recovery and open resetlogs.
Since you have a backup controlfile, Oracle cannot know what the last logfile number was, so just asks you for another. I think you gotta tell it there aint no more.

Subject: Recovery with hot backup
I am testing out my backup/recovery strategy. As noted in my previous posting, I am using the following to back up my database while it is on line:
alter tablespace xxx begin backup;
<copy data files for tablespace xxx>
alter tablespace xxx end backup;
... ( for all tablespaces)
alter system switch logfile;
alter database backup controlfile to 'xxxx';
To simulate a complete system failure, I then shut down the database, and deleted all data and control files, including my online redo logs.
Then I copied my data files and backup control file back to their original locations and ran svrmgrl:
SVRMGR> connect internal
connected
SVRMGR>startup mount
...
Database mounted.
SVRMGR> recover database using backup controlfile;
SVRMGR responds:

arch.log1_10299.dbf does not exist and, as far as I know, never did. I did not delete it, in any event.
What am I doing wrong here?
Why svrmgr think that there should be another archived log file?\
BTW, I am doing this on a test instance for which I have a cold backup, so, if there is something missing from my backup I do have the option to put the whole thing back to the status quo ante and start over with the a revised online backup.
thanks,
