Dear all,
Here in my shop the usual way of addressing a SMF record search is through the Batch job using the utility. But, I was going through some post and tips SMF records can also be processed through REXX provided the format VBS can be converted into FB through sort or some other utilities like ICEGENER. Yes, I had good information on the convertion through some post's and documents. But, My intension, say for eg: i would need to search whether this particular dataset is used by system or not. Any inputs would be helpful. Apologize if i or my thoughts or wrong! also let me know if i need to give more information.

Regards,
Viswa

Hello,

If there is already a utility in place that will do an SMF record search, why is something else needed?

Can you not just search for the datasedt of interest?

Many organizations already capture job, program, and dataset information for use by developers and support people so they do not need to reference raw SMF data. You should ask whoever supports SMF on your system what might already be available.

the best tool ( FREE ) to extract from the SMF data all You might know about dataset utilization is DAF

no need to rewrite when something is available.

If you are in a direction to create some "tools" which can be used by your current shop, suggest you get familiar with what is available and what is not.

E.g. as you said

My intension, say for eg: i would need to search whether this particular dataset is used by system or not.

- to create such a tool would be a futile effort. If you locate the DSN using ISPF 3.4 and hit PF1 twice, you know what you are looking for.

FWIW.

If you locate the DSN using ISPF 3.4 and hit PF1 twice, you know what you are looking for.

Can you explain more?

If you are asking thi s Pedro that means, I was failed to explain it well, before:

Menu Options View Utilities Compilers Help

and you hit PF1 twice, you'll get this

where "T1234AD" is the RACF ID of the person who has opened it for edit.

unless I completely misunderstood ( SMF reference )
the TS does not want to know about utilization as pending ENQ,
but rather wants to know when a dataset was referenced and by whom ( probably )

by **dick scherrer** » Tue Aug 07, 2012 8:06 pm

Hi Enrico,

Yup, that is the way interpreted this questoin also.

Maybe TS will clarify . . .
