Reply with quote

Hi,

I am in a need to create a small subset of MAN dataset in "VSAM format". I am aware that we can dump MAN dataset using IFASMFDP and create a PS VBS file.
But is there any way we can create, a VSAM file which is exact replica of MAN dataset.

The requirement is to tune the SMF dumping job by altering parameters in the job. So in need of a MAN dataset to play with.

If I copy a PS VBS SMF file into a VSAM file with MAN dataset attributes, would it be exact replica of MAN dataset to test?

I don't have much experience working with MAN dataset, so pardon my ignorance. SMF files in PS VBS files have always been my thing Im used to.

Thanks & Regards,

the more time passes, the more I feel that copying a smf file into a vsam file is a bad idea and won't work

Code:
  DEFINE CLUSTER( -
      CONTROLINTERVALSIZE(4096) -
      CYLINDERS(40) -
      NAME(SYS1.TECH.MAN1) -
      NONINDEXED -
      RECORDSIZE(4086,32767) -
      REUSE -
      SHAREOPTIONS(2) -
      SPANNED -
      SPEED -
      VOLUME(OSACAT) ) -
    DATA( -
      NAME(SYS1.TECH.MAN1.DATA) ) -
    CATALOG(SYS1.MASTER.CATALOG.VOSACAT)
will work, but you will need to change the names appropriately -- and you need the appropriate security authorization, of course. Once defined, I would expect REPRO would copy the data from one of your existing files.

Thanks Robert for your thought,
Are you saying that REPROing an existing SMF PS file into a VSAM file would work?
I would give it a try now.

I would define it, then REPRO some of the records from the current SYS1.MANx into the new file. PS to VSAM might work but I haven't tried it so I cannot say for sure.

Okay Robert, Thanks again, I would copy from one of the free MAN datasets.
