Re: BPCS 604 x V5R2 OS/400

Several suggestions
* 1. Note that as OS/400 adds more stuff, it needs more hardware gas to sustain the same performance, in which from time to time you may need to consider getting more 400 memory (for cache) or a faster processor.
* 2. One reason why some BPCS programs go slow is the sheer mass of records in files being accessed ... like we have 1 year of inventory history, but 99% of our users only need to see the last few weeks worth ... there are archiving solutions such that you have access to the data you need, but not have millions or records clogging up inquiries.
* 3. We took a hard look at what we were running interactive vs. batch when our BPCS 405CD moved from Os/400 V4 to V5 and moved some interactive functions to batch.
* 4. There is such a thing as studying the reccommendations given by SQL messages when you running programs that are going slow, and thanks to that adding some more logicals that will help those jobs run more efficiently.
* 5. IBM pricing is pushing pricing on certain kinds of processing way up relative to other kinds of processing ... there is programming modification that can be done to move workload from the artificially high IBM pricing to the artificially low IBM pricing ... not my favorite solution, but I just giving you alternatives.

Hi Everybody,

We'd changed the OS/400 version from v5r1 to v5r2 and after that our BPCS
programs had a performance problem in several applications.

We are in BPCS 6004 MM.

Did anybody have the same problem ?

We already saw the IBM APAR, PTF SI14837 apllied, and DB PTF is in 17 level.

Thanks in advance.
