Recover database until time - doesn't recover as expected

Question

Hi,
We've got an Oracle 9i db (9208) running on AIX.
We've had a problem and that has meant restoring all the dbf's and control files from the over night backup onto the server replacing the currently corrupted system.
Once this was done we then opened the DB in order to check some things.
Once this was done we then closed and mounted it and issued the "recover database until time .... " command.
The archive logs we need are in the default archive location. They cover the time period just prior to the restored files up until the time we need the DB recovered to.
However, when running the recover the alert log just shows
"ALTER DATABASE RECOVER database until time '2010-08-11:16:30:00'
Mon Aug 16 14:33:57 2010
Media Recovery Start
Media Recovery Not Required"
Can anyone tell us why the recover command isn't recovering the archive log files up until the time we are specifying. It doesn't look like its even looking at them.
The command executes in less than a second.
Is this because we opened the DB between restoring and recovering so its already written a newer archive log file, so the DB thinks its already up to date???

Answer 1

Got it - thanks
Basically cause we were also restoring the control file so when adding the "using backup controlfile" it then started to work.
SQL> recover database until time '2010-08-11:16:30:00' using backup controlfile
ORA-00279: change 276395529 generated at 08/10/2010 21:59:38 needed for thread

ORA-00289: suggestion : /archive_logs/tprod/arch0000070260.arc
ORA-00280: change 276395529 for thread 1 is in sequence #70260
Specify log: {<RET>=suggested | filename | AUTO | CANCEL}
This was the first message we got once we put the "using backup controlfile" part into the command.
We selected AUTO and its now slowly working through all the archive log files going up the numbers therefore i assume applying the archive logs correctly.
Once this is done i believe we just "alter database open resetlogs"
