Oracle Error Message
RMAN-06026: some targets not found – aborting restore
Reason for the Error
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.
Solution
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.
