Hi,

I'm given a list of some RACF IDs which are claimed to consume a very High CPU but for whcih JOB & when it was high against their IDs is not availble to me. I can ask "those Guys (who sent me the list)" to provide this information but any how they are not responding well & it's a very long channel, for me, to get this info, this is really tedious for me to have my query with option TYPRUN=HOLD and makes me to put this query.

I didn't play much with SMF records but any how it seems that they can be of my use, is it possible to get the such information, such statistcs for some one others' ID while I'm logged in to Mainframes with ID ? (Probably you can understand with my question construction, how much do I play with SMF records.. icon_redface.gif )

SMF data can be accumulated as long as you have access to the files; there's no restriction that I'm aware of with the job RACF user id. However, something like MXG or MICS makes it much easier to get to the data. You might check with your site support people to see if one of these packages is being used there.

SMF data is system wide data, that records - depending on the record types collected - everything that happens on the system.

If you have read access to the dumped SMF data and can use SAS to get the statistics you need - with a lot of trial and a lot more error icon_lol.gif

As Robert has said - if you have MXG or MICS available - talk to the sysprogs / performance & capacity / storage management teams to see if they already produce the reports that might interest you, and see if they can give you the code to find out what you need.

I might have some of "ye olde" SAS programs somewhere but fear that these have been deleted as it is about 20 years since I have done any cap & perf work for real.

The SMF record type 30 subtype 4 should give you quite a bit of info about what the CPU usages were.

Subtypes 2 & 3 can be used for interval reporting, but I'd guess that the overall picture is what would interest you the most.

Might help you get what you want.

Thanks Expat.

As I'm an application engineer & not a system programmer, only thing I'm afraid of is, whether I would be having asscess to such a data or not. However, I gonna give a try - they allow such violation (if it is) three times before invoking the ID.
