RMAN-06522

Error: RMAN-06522: KEEP FOREVER option is not supported without the recovery catalog

Causa: The KEEP FOREVER option was used, but it requires a connection to a recovery catalog database. The KEEP FOREVER option cannot be used when the backup repository is the target database controlfile. This is because information about this backup cannot be permanently stored. If information is stored just in the controlfile it will be aged out depending on the CONTROL_FILE_RECORD_KEEP_TIME initialization parameter.

Acción: If a recovery catalog database is available, then connect to the recovery catalog and retry the command. Otherwise, use a different KEEP option.
