Hello Joe:
The short answer is yes, it looks like you need to restore your data base from
the
most current backup.
In addition a suggestion so that hopefully you will not see this problem
again in the future.
First, I assume that the ADSM server was still running when the system was
IPLed.
I do recommend that you halt the ADSM server before an IPL. I understand that
in
an EPO situation the server can not be halted first. In that case you need to
use ADSM
mirroring on your recovery log. I also recommend using
MIRRORWRITE LOG SEQUENTIAL
in the server options file along with the mirroring of the recovery log. This
will have a
performance impact but will improve recoverability after an EPO situation or
even an
IPL without halting the server. I do not know how much of a performance impact
you
will see with the MIRRORWRITE LOG SEQUENTIAL option. If anyone has done any
testing and has some performance numbers on that I would be interested in
knowing.
Hope this helps
David Bohm
