My old environment(s) ran with the configuration that Matthew mentioned -
SRDF mirroring for just ASM disk groups for databases - but that was for
DR purposes - in the event of a DR / or during the drill - we'd register
the production database(s) with the DR side cluster and run them - we did
have to make a few changes to the databases in terms of getting them to
register w/ the SCAN listener on the DR site - but other than that - it was
a working scenario.
Thanks,
