The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
IIRC there are some group PTFs for the DB2 group that you should apply
that will fix *some* of the problems you are having.
Thanks,

unexplained performance problems with SQL after upgrading to V5R4
Hi, all:
One of our large customers upgraded their production system from V5R3 to
V5R4 last week-end.
They re-initialized all of their DASD and re-loaded all of their data
from back-up tapes, during or after the upgrade to V5R4. They say access
paths were saved (and restored), so they are not seeing index rebuilds
going on.
The problem is, for their applications that use embedded SQL, they are
seeing much slower performance, versus what they saw a week ago, when
they were still running on V5R3.
Does anyone have any ideas about where to look, or what to look for?
Perhaps some values changed in QAQQINI?
Thanks in advance for any suggestions, hints or tips.
Regards,
Mark S. Waterbury
