UBE\'s on the 400 & IBM O/S 400 support & DASD PTF\'s
It has been my experience that UBE's run well on the AS/400 and/or iseries
400 but only if configured properly. In other words, think about creating
an additional batch subsystem (try not to start with the letter "Q", this is
reserved for IBM objects) for the UBE's and "DEDICATE" an appropriate amount
of memory to that subsystem.
Try to ensure your total % DASD utilized does not exceed 70% (wrksyssts, top
right hand corner). Keep your O/S current, Keep your O/S current and Keep
your O/S current. Review and implement (carefully) the performance tuning
recommendations on the Knowledge Garden. I believe there is also a white
paper(s).
If you have the LPP performance tools (5769PT1) execute and review the
performance reports against a job, user, subsystem, overall system etc.....
I usually "fire up" this tool when the CPU is very high, but you can execute
anytime. Maybe you want to execute when a slow performing UBE is executing.
You could then print (or review online) exactly what that UBE is doing.
EXCELLENT tool if used properly and well worth the exercise.
An example
========
1) go perform
2) select option # 2
3) select option # 1
4) select option # 2
5) Try to use QPFRDATA for the library
6) 1 and 1 would be good
7) 15 & 1 would be good
8) your call
Remember, O/S 400 "out of the box" is not optimally configured for superior
OneWorld performance.
I have noticed several AS/400 configuration that are still on O/S 400 V4R3
and V4R4. See below, get current, it's important.
