Oracle Error Message
RMAN-08602: channel string: no AUTOBACKUPS found in ASM disk group string
Reason for the Error
The specified ASM 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 values used for the format of the CONFIGURE CONTROLFILE AUTOBACKUP FORMAT command and DB_UNIQUE_NAME to verify whether the ASM area location is set correctly. Note that the DB_UNIQUE_NAME can be specified as option to the restore command.
