Listing EVERY Dataset on a system

DaveV · Posted: Thu Jan 09, 2020 7:48 pm

Hi all, new here. I am not sure which sub-forum this belongs in so I will start here. We have a mainframe which needs a major DASD/Dataset cleanup. I would like to extract a listing of all datasets that are cataloged (and this that aren't if possible) into a flat file and download it to my PC do some analysis. I know how to get a listing of all catalogs, then dump the contents of each catalog via IDCAMS/LISTCAT but the listing is in multi-line format and not conducive to PC analysis. The Info I would like is creation+expiration date, volume, size and anything else relevant. Even if I could do a list via TSO option 3.4 and save the output so I could download it, that would be great. Any and all advice/ideas are appreciated!

DCOLLECT would be one way to do it -- check out the Access Method Services manual.

Install the VTOC pgm from cbttape.org file 112. I gives you a nice customizable list. It is based on the VTOC (obviously) but one option is to check for cataloged status.

Hi David,
The ISPF 3.4 option may not suitable in this case because the TS wants list of all datasets, and to list datasets in 3.4 we need minimum of 1 qualifier in the dataset name.
It may not be possible to manually put in all available HLQ to get a list.

However I agree that SAVE LIST command saves the 3.4 list and is very handy.

For the initial question, I think IDCAMS DCOLLECT is one of the good sources and I would go with processing it.

Regards,
