RMAN-06100: no channel to restore a backup or copy of datafile %d
 *Cause:  A datafile, tablespace, or database restore could not proceed
          because the backup of the indicated file exists on a device type
          that was not allocated for restore.
 *Action: None - this is an informational message.  See message 6026 for
          further details.

RMAN-06026: some targets not found - aborting restore
 *Cause:  Some of the files specified for restore could not be found.
          Message 6023, 6024, or 6025 is also issued to indicate which
          files could not be found.  Some common reasons why a file
          can not be restored are that there is no backup
          or copy of the file that is known to recovery manager, or
          there are no backups or copies that fall within the criteria
          specified on the RESTORE command, or some datafile copies have
          been made but not cataloged.
 *Action: The Recovery Manager LIST command can be used to display the
          backups and copies that Recovery Manager
          knows about.  Select the files to be restored from that list.

Regards
Michel

I appreciate your quick response Michel.

the backup of the indicated file exists on a device type that was not allocated for restore.
If the above is true should I be able to see the backupset when I issue list backup? I mention this because when I run this command I see all backup files with its tag number showing the exact location of my backup.


some datafile copies have been made but not cataloged.

I have not cataloged my DB backup. Do i need to do that? If yes can you please help me with that?

Thanks,
SN

You try to restore from a disk channel, if, for instance, you used a tape channel to backup then a disk channel is unable to restore.
Check the channel you used to backup.
Execute a LIST to see what are your known backups.

Rman>backup database plus archivelog;

I think I'm using disk channel and not tape channel (sbt).

Execute a LIST to see what are your known backups.
Thats what I was refering yesterday that I can see the backupset when I issue list backup on my DB. Please suggest..

The above I copied was from yesterday's backup so no I cant restore. I know that the backup is correct and its been recognized by the DB. I'm missing something that has to be done before restore. Please suggest.

I thought we already deal with this.
You need to do a point in time recovery.

Hey Mahesh,

Well the Point in time recovery never worked for me. I've started all over again but this time the different(good) thing is that my RMAN recognizes the backupset but doesn't cooperate to restore. I know you have wasted too much time with me. I apologize for that Sad .

Thanks,
Shekhar
