I know the command LISTDS can display the member name alone in the PDS .
Is there any specific command (or JCL utility ) to display the dataset information ,ie, the PDS name date it created date modified,
If so please let me know the command name or the JCL.

Thanks in advance..

TSO command LISTCAT

[saravanan80]

Will this LISTCAT will work when we give as a command in JCL.. if so can u please provide me the JCL step.

just execute tso in batch - plenty of examples available in various groups here e.g. TSO,ISPF. Batch tso is IKJEFT01 (amongst others)

I feel the Listcat command will reveal the volume on which the dataset resides . but It won't give the date it created and date it got modified etc.

I think that you can use IEHLIST to get that info for non-migrated data sets. But that information comes from the VTOC so I'm not sure how the last referenced data is managed, particularly if the volume is mounted read-only (since the system could not update the VTOC in that case). It seems that this info should really come from the catalog, but I didn't see it in LISTCAT output either. Maybe looking at the data returned by the CSI interface would reveal it.

You can see a sample of IEHLIST output in ISPF by looking at the bottom of a listing produced with

TSO ISPMLIST data-set-name FORMAT

Note: Do not use ISPMLIST in your code!! It is an undocumented diagnostic Rexx that does nothing more than invoke IEHLIST and show the output in a Browse session. This also works only with non-VSAM data sets.

Another way to get the VTOC information for a data set is through the LISTDS command with the LABEL operand, but you need to interpret the label information yourself. The label information is described by the Format-1 DSCB but decoding the dates is not trivial. An example of doing that in Rexx is available in this edit macro.

Having said all that, you'd do better to run ISPF in batch using IKJEFT01 and running an exec that uses one of the ISPF services. The DSINFO service will give you the info you seek.

The command that u had provided wont give the result , is there anyother command to acheive this result.

Sarvanan,

How about this ?

[semigeezer]

What result are you looking for exactly? Just saying something doesn't work is completely unhelpful, especially when you were given 3 very detailed options for getting the information you asked for, as well as a technical explanation of where the data is stored by the system and how and when it may be updated. If you have tried something, let us know what, what errors did you get, etc, etc, etc. We are not mind readers and personally, I expect a little more of a response than 'it didn't work' for the time I took to research, document and add references and links to the response.

Note that MVS does not keep a modified date for data sets, only create, expiration and last referenced date. LISTCAT (IDCAMS) shows the create and expiration date. IEHLIST shows the same. DSINFO can get the last referenced date too. For updates you'd need to use SMF records which is not worth the trouble. Please be specific in your responses.

Hi my actual requirement is when we get in to a PDS with 3.4 option it will display the list of members in it , the creation date , last modified date and last accessed ID , when we give savelist all those details will be saved in a flat file, instead of getting the result manualy by giving savelist command is there any utility or command that can be used in a JCL to acheive the result ..
