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

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....

 World.......

Mark,

Per your suggestion I ran the STROBJCVN over the JDE libs yesterday and
did see some improvement in performance as a result.  I was aware and
did this when we went from V4R5 to V5R1 last spring as part of my post
install tasks.  There was a known performance hit initially for object
conversion if you did not do this.  I guess it is true for V5R2 as
well..............

I did a total V5R2 shake down last night to see what I really had beyond
any doubt.  I found that the HIPER PTF group did not apply, yet it is on
the same CD as DB2 and it did apply.....Working to get that resolved
right now.

Slooooooowly but surely it's coming around........

Thanks!
