Recovery issue

Recovery issue

Hi All,
I am performing a restore and recovery from a database image. Before performing a recovery I am deleting all the database files (datafiles, control files, redo log files, archived redo etc) to go in time to point when backup was taken.

My restore was successful but I recieved an error while recovery. The error is as follows:
unable to find archive log
archive log thread=1 sequence=82
Oracle Error:
ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below
ORA-01194: file 2 needs more recovery to be consistent
ORA-01110: data file 2: '/db/oracle/u05/oradata/DB/undotbs01.dbf'

RMAN-03002: failure of recover command at 12/07/2007 16:02:13
RMAN-06054: media recovery requesting unknown log: thread 1 scn 629113

Then I checked the backup sets but found that archived redo of thread 1 sequence 82 is present in the backup i m restoring.

Eventhough the archived log is backed up why is it having issues while recovery. Why does it say unable to find archived log?
Could someone help me understand the issue?

Re: Recovery issue

could you explain a little more on your backup strategy(hot,cold,consistent split) and db status during the whole backup process.
