I worked in MQ performance on z/OS. This uses the same logger as DB2, and
similar ways of access data on page sets.
I see there are different sorts of workload.
Mainly sequential write For example writing to the logs.
- These write n * 4K pages, where I think n is up to 32. These perhaps
Ideally you'd run all your ordinary workloads but in a stress testing way, with
simulated demand, ordinary concurrent batch runs, and valid test data. And then
dial up the stress to +50% (for example) above your prior peak if you want to
see that.
Simulated demand implies you'd have a load gene

Not so much as to where to find the statistics. Rather, a set of benchmarks to
produce the statistics. Thanks.

IIRC - the RMF/SMF record type 74-5 can you provide the I/O rates, Cache

I have been asked for ideas in regards to DASD benchmark testing. We would like
to compare IBM DS88xx's against competitors. Something that would generate
statistics for I/O rate, response time, and exercise track change rate
(replication performance).
Something free of course. Thanks in advanc
