Oracle Error Message
RMAN-06584: WARNING: AS BACKUPSET option added due to allocation of multiple channel types
Reason for the Error
DISK and non DISK channels were allocated for a backup command. Configuration indicates to produce image copies to DISK, however due to the mixed channel types BACKUPSETS will be created on DISK.
Solution
Do not allocate non DISK channels to produce image copies to DISK or allocate only non DISK channels to produce BACKUPSETS only.
