Actually our SMF dump job dumps to a daily tape which in the next step
is mod on to a weekly tape using IEBGENER (actually ICEGENER in our
case). This weekly tape is then concatenated to a monthly tape once a
week. I keep multiple generations of the daily and weekly files so I can
easily rebuild if needed. Does this sound ok?

Sounds reasonable to me, George. Here's what we did at Clearing:
1. Our IEFU29 exit issued a command to start the SMFDUMP proc. This proc
used the old IBM "SMFDUMP" program to dump all non-empty SMF datasets to
DASD GDS. Second step was to sort the resulting dataset into time/date
sequence, using DFSORT and the SORT exits recommended for processing RMF
data. Split-outs of certain records for reporting purposes was done in a
third step, making COPIES of the required records. These "subset"
datasets were deleted when the appropriate reports were generated.
2. Weekly, use DFSORT to MERGE all those GDS's, in time/date sequence,
to a single dataset on tape, discarding certain records that we knew
positively that we would not be using again, like 14/15 for TEMP
datasets. We had a CLIST that we used to generate the actual MERGE JCL,
based on the number of catalog entries for individual dump datasets.
We chose to use DFSORT as much as possible, because IFASMFDP was so
incredibly SLOW!! In spite of advice to the contrary, we never
experienced a "broken record", even across a system "crash".
We had to make a slight modification to the SMFDUMP program. With
multiple images in a sysplex, we occaissionally had SMFDUMP starting on
more than one image at once, so we modified the ENQ that it does (to
prevent multiple instances running in parallel on one image) to include
the image name, extracted from the SMFCA.
This is what worked for us. YMMV.
