RE: Power Outage story ...

>From the manual, I think SMAPP is turned on by default:

"For new systems, the system-wide recovery time for access paths is 70
minutes, which is the default. If you move from a release that does not
provide the SMAPP function to a release that does supports SMAPP, the
system-wide recovery time for access paths is also set to 70 minutes."

HTH,
Charles
