Hi ,

Can someone tell me how to collect the SMF data ? I tried searching the Forum , but I could only find some IBM Manual for this ,which did not help me much.

This would be the realm of the systems programmers.

You will need to speak with them, and whoever else who may be responsible for the dump and accumulation of the SMF data.

Hello,

Depending on which smf records you want to work with, your storage management people may already have things in place that you could use or clone for your use.

You can also select smf records using DFSORT (there are examples in the DFSORT part of the forum).

There are usually established procedures and standards set up by the systems programmers to collect SMF data; any JCL you run could interfere with these established procedures and cause problems. You really need to contact your site's systems programmers to get JCL from them, not from this forum.

Furthermore, the specific SMF record types collected are controlled by the systems programmers and based on site requirements for intervals, third party product SMF data, space requirements, performance monitoring, and capacity planning.

Hello,

Following is the link to the DFSORT manual which shows how to select particular smf records.
http://www-304.ibm.com/systems/support/storage/software/sort/mvs/tricks/pdf/sorttrck.pdf

As Robert mentioned, you would not want to interfere with already established procedures (and you surely do not want jcl that you happen to find on some forum).

This is why i suggested your storage management people. At many sites i've supported they already have procedures in place to provide a subset of the smf data for various analysis purposes. If they already have something in place, they can show you what you need to do to use it. If nothing is in place, they can show you the proper way to do what you need to do on that system and not interfere with the already established procedures.

You did not say what manual it was.

For the general idea of how SMF works and how to use, google for SA22-7630-16 and read chapter 1 and 2.

Hello,

It may help if you post why you want to use smf data. . .
