Given a Qualifier : Identify Total File Size

hi,

i have a query to identify the total file size with a specifiec high level qualifier.

For example,
In my developement region, i want to find the total size of the files whose names are starting with the qualifier 'DEV.REG'.This includes all kinds of files(Flat,VSAM,GDG)

Please let us know if there is any JCL or Utility like IDCAMS or any other method is available for the same.

Thanks in advance,
Chinna.

Hi Chinna,

Hello,

If you use IDCAMS in batch, you can create a "report" of the datasets you are interested. With a bit of code you can read the "report" and calculate the total space used. This will work for dasd files.

If you want to find how much data is stored on cart/tape, you should be able to get the total from the tape library system (or the storage management people who support the tape library system).

Look at the Smart Tricks document that Frank has published, I think it has something to do just that.

There is a trick for "Dataset counts and space by high level qualifier", but it requires some pre-processing of DCOLLECT records so it may or may not fit the requirement.

For reference, the DFSORT Tricks are at:

Hi,
if you can obtain a list of the dataset names as previously mentioned using IDCAMs, you can then input the file containing the fully qualified dataset names into the command LISTDSI

You should be able to call the command via REXX or CLIST.

eg.
X = LISTDSI("'"DSN"' NORECALL ")

Hi,
I forgot to mention that LISTDSI does not support TAPE or VSAM files.

in case that the dfsort dcollect samples should not be enough

take a look at cbt FILE 206 , at Use [URL] BBCode for External Links,
it contains a REXX application to process dcollect data...
