Phil,

I haven't gotten into PT enough.  But I'd think that it would treat LAN
attached CA terminals just like the twinax.  I'm only basing that on the
fact that the WRKACTJOB APIs do, so I would think PT would also...

I don't recall if I said, but Mike really hit the nail, with this one...

| Mike,
|
| (jt:  You might want to read this, too.)
|
| I really like the format you are using with the various time
| buckets.  After
| running down several dead-end paths,  the only performance file
| (QAPM*) I see
| that has this kind of information is QAPMRESP which is for twinax attached
| workstations only.  The Performance Tools Manual shows a report
| for Locally
| Attached Workstations as well as one for Remote Workstations.  I
| am not finding
| this type of info for LAN attached Client Access type workstations.
|
| Is your report showing the Client Access workstations or just the
| twinax type?
|
| If I understand correctly, Performance Tools presents reports and
| screens based
| on the data that is collected by the QPFRMON job that starts when
| you run a
| STRPFRMON command.  (I am not sure if/how this is related to the
| CRTPFRDTA job
| that is always running in QSYSWRK.)  We don't have Performance
| Tools, but before
| I spend money, I would like to have some assurance PT can
| actually provide the
| info I need.

|    Enough of my stories.  My thought is that you use another metric for
|    response time.  This assumes you can get someone to buy into
| the idea that
|    sometimes response time is an application problem or design
| issue.  I think
|    this is real critical.   What we measure is the 'distribution curve of
|    response times'.  Everyone is going to be slightly different
| but what we
|    measure is the standard 4 buckets: 0-1 second, 1-2, seconds,
| 2-4 seconds,
|    4+ seconds.  95% of our transactions fall within sub-second,
| 98% within 2
|    seconds, and so on.   Right now I forget how we track that but
| I am pretty
|    sure it is a component of performance tools.
