RE: Model 270 At V5R2 Is Dead Toad Slow Running JDE One

["Mike Shaw" <mhshaw@xxxxxxxxxxxxxxxx>]

Scott,

This was a V5R1-to-V5R2 upgrade.  We made similar changes going from
V4R5 to  V5R1 last spring plus we ran some object conversion to avoid
the one time performance hit when an object was touched the first time
at V5R1.

I ran the STROBJCVN over the JDE libraries yesterday and that seemed to
help the performance.  We also found that there were some PTF issues in
that the HIPER Group PTF did not apply.  Got that fixed at noon today
and it seems to be doing better from a performance perspective.

Thanks for the info.

Regards,

Mike Shaw

Mike -

I don't know if this is your problem or not, but I've seen two instances
of
major performance degradation after a V5R1 or V5R2 upgrade from a V4
release.  Both of these involved a single service program compiled with
activation group=*NEW  When recompiled with activation group=*CALLER the
performance straightened right out.  I don't know all of the nuts and
bolts
details, but apparently there were some changes to the CLE compiler in
V5,
and the previous defaults are not optimal.  

I hadn't heard of this with JDE though, I saw it in WAF and a similar
incident was discussed here earlier this month with some EDI sofware.

We tracked this down by running performance traces and discovering that
one
single job was chewing up a large percentage of the CPU time.  Of course
it
took two months to convince IBM that it was an issue....
