RMAN-06563: control file or SPFILE must be restored using FROM AUTOBACKUP

Backup and Recovery best practices dictate that we must use a RMAN recovery catalog and also have the controlfile AUTOBACKUP enabled.

If we do not do either and we lose all the controlfiles, we cannot restore the controlfiles even if we have taken a backup to tape as shown in the case below.

We will encounter the RMAN-06563 error even if we set the DBID or explicitly alllocate a channel for a tape device.

RMAN-06563: control file or SPFILE must be restored using FROM AUTOBACKUP

However, if we connect to a RMAN recovery catalog, we can restore a controlfile without using the AUTOBACKUP keyword.

$ rman target / catalog rman9p/xxx@rcatp
