Dear folks;
As a possibly a neverending debate, I wanto to know, besides storage and
CPU usage implications, what are the benefits of not having all the smf
records ON with the exception of 4,5 and 99.
I don't have neither the VSAM SMF records ON nor the CICS record ON. I run
about 10k+ Jobs daily and I have about 25 production CICS regions.
My config are one 2084-303 and one 2084-304 running about 85% capacity.
I think it has been discussed lately.
The cost of SMF records is not only a cost of storing them, but also
cost of creation. So, if your application creates SMFrecords, but due to
PARMLIB options you drop them, it preserves I/O, storage, a little CPU,
but it is still CPU consuming - because records are created. BTW: Cost
of offload jobs is rather irrelevant, beacuse usually they don't burn
CPU cycles during "rush hours".
