Hello All, I know this is an MQ forum but I'm not getting any responses from the mainframe sites other than wise-cracks so I thought I would try you all.
I am tuning DFSORT and I would like to be able to report on the SMF type 16 records There is no canned RMF report available.
Does anybody have some code or a utility that would report on this info I could download or copy please? If not can you point me to a web site please? |

Well. I don't know how to read it, but I found something that looks like it would suit the bill in one google search.
Have you tried the google? |

That's either optimistic or you don't spend much time here....

Really? No RMF? Are you entirely sure? Have you tried hitting the sys progs with something harder and/or heavier?
You might be able to mug something up with ICETOOL.

Well it's only an SMF record; any of the usual suspects should be able to handle it.
This may be where the wise cracks are coming from. Everyone (including me) is misunderstanding your issue because it sounds simple on the face of it.

Why do you believe that you need to tune DFSORT?
Are all sorts misbehaving? Or just some sorts? Have you read through the DFSORT documentation? Do you understand how to pass parameters to the sort at execution time to improve performance for a particular sort execution?

I am the Systems Programmer and I don't have time to bother writing a stupid COBOL program. I'm sure I'm not the only SP in the world collecting SMF 16 records, I was hoping somebody would have something to share.
DFSORT was installed with all the IBM supplied defaults. I was hoping to save some CPU by tuning a few options. The only way to convince management of anything around here is a report or chart....I need to be able to backup what I say. |

CPU time? I'd be more concerned with I/O. Which few options?
DFSORT should run just fine with default values for most/many of the sorts you run.
You can improve throughput (basic tuning) for individual sorts by tuning individual batch jobs.
For small sorts, you do basic tuning for a batch job by providing DFSORT with sufficient REGION on the EXEC statement.
You do a bit more advanced tuning by specifying the number of records (explicit or estimated) at execution of the sort.
If you know the number of records, SORTWKxx DD statements will provide the sort with disk space to work with.
This is all discussed in the DFSORT documentation. Have you read it? Do you understand what you've read?

What application does your shop use to analyze SMF type 15 records?
