Paul et al.,
I agree with Paul's setup of a dedicated RMAN catalog
server. It is not a bad idea to have the datafiles for
this database on mirrored volumes. I also think a good
practice related to "saving the catalog" against tape
media errors is to do a full export on the RMAN
Catalog DB and stash the export dumpfile away on a
mirrored volume away from the datafiles.
If this DB has nothing but the RMAN catalog, it should
not be very large (let me know if this is otherwise)
and thus the full export will be a good method to have
a "logical backup". One more thing to save the skin on
your back, at a time of need. When Murphy is around I
think the word "mercy" vanishes from the English
dictionary.
Cheers,
Gaja
