First off I too have experienced the same CFINT problem on a 6xx system.
Absolutely not @#$% idea why it would hit so hard on a system that is
allowed to be ALL interactive.  OK that said, I have not been able to find
the PTF mentioned for V4R5.  If anyone can lend a hand here that would be
great.

Maybe the revenue stream was starting to dry up and they introduced the
"hardware upgrade inducer code to V4R5"

This from an email newsletter(?) called
" November '01 - Performance Update
    Topic of the Month:  5250 Interactive CPW and WAS 4.0 Performance
Report "

In it the following longish discussion:


<snip>
Q.  My customer recently went to V5R1 and the 5250 interactive performance
seems to have changed.  Is there a problem?
A: Unfortunately, the integration of new iSeries function into V4R5 and
V5R1 resulted in tighter controls being applied to a customer's use of
interactive capacity beyond the published 5250 Interactive CPW levels of
capacity.

When  the published 5250 Interactive CPW levels are exceeded, long running
5250 interactive jobs are not being managed the same they were managed at
V4R4.  As a result, some customers have experienced different performance
characteristics when compared to V4R4, even though they were running very
similar workloads.

   V5R1 Customers:
   If you are operating at or beyond the published 5250 Interactive CPW
   capacity levels for your configured server and are experiencing  the
   situation outlined above, then apply PTF #MF27323 (Included in the
   latest CUM package #C1302510). After installing  PTF MF27281, customers
   should expect to see V5R1 interactive performance  characteristics
   consistent with V4R4.
   V4R5 Customers:
   If you are operating at or beyond the published Interactive CPW
capacity
   levels for your configured server and are experiencing the situation
   that was outlined above, then you can upgrade to V5R1 and apply PTF
   #MF27323 or you can wait to apply  a V4R5 PTF that is currently under
   development (target  availability is Dec 31, 2001).  After installing
   the forthcoming PTF,  customers should  expect to see V4R5  interactive
   performance  characteristics  consistent with V4R4.

==========================================

You know Jan, the timing of this is great (for me) because we are on a
620-2179 and at V4R1 CFINT never seemed to do much when viewed via
WRKSYSACT. I upgraded to V4R5 in November and just noticed today (via
WRKSYSACT) that unless I was seeing things, the % for CFINT seemed to be
jumping around and it was NOT in V4R1... (? ? ?).

I was always under the impression that from the really smart folks when it
comes to this stuff (Leif, Neil, etc. <G>) that the 620-2179 was "immune"
from this ?

Comments, anyone ? :-)
