Oracle Error Message
RMAN-08547: channel string: no AUTOBACKUPS found in the recovery area
Reason for the Error
The recovery area does not have desired AUTOBACKUP.
Solution
Check the option UNTIL TIME in case an existing AUTOBACKUP does satisfy the criteria specified in the restore command. Otherwise, verify the init.ora parameters DB_RECOVERY_FILE_DEST and DB_UNIQUE_NAME to verify whether the recovery area location is set correctly. Note that the parameters can be specified as options to the restore command.
