Question: If a database is backed up using an rman catalog, but the
control_file_record_keep_time is set to zero, will the rman backups be
reliable for restore?



Openned a metalink ticket, analyst says:

Your RMAN backups will be usable because you are using an RMAN catalog.
The records in the control file always get truncated, regardless if the
control_file_record_keep_time is set to 0 or 7 (for example).
The problems with control_file_record_keep_time = 0 start only when NOT
using an RMAN catalog



Oracle documentation says:

...there is a possibility that backup records may be overwritten in the
control file before RMAN is able to add them to the catalog.



Does anyone know which is correct?... or should I ask under what
conditions perhaps they are both correct? I am presently working on this
as a production issue...

Thanks in advance for your feedback..
