You cannot argue that the complexity of RAC can add to the operational
challenges of supporting Oracle. Just think about what might happen if
you have an unskilled DBA walking into a site that already has your RAC
installation and has never supported such? Even an unimaginative,
non-experimentally minded DBA will have problems with that one!

Have you polled each and every one of them to assure that not one has
experienced an unplanned outage? With all the reports on this list, and
my experience with just starting up Oracle 7 OPS after a reboot taking
*** HOURS ***, I think we can safely assume at least one of them has had
to address an uptime issue we've disucssed on this list!

Good that you mention the most currently stable environment. This
actually implies there are/were issues, as have been discussed in prior
threads.
