However, you may not have the required access to do this.

Any changes should be discussed with your storage management people before even attempting this.

Hi

I have access to do it , as its a live support work.
But as lot of files hence its a tough to do manually.

Is there any way to process files name with wild cards in rexx?

since You seem to know little about REXX, why not simply ask how to do it ???

anyway no need for REXX, nor in house programming/scripting

use ISMF to create a customized/filtered dataset list

after that ...
see the ISMF model command generation facility ( here for example )
publib.boulder.ibm.com/infocenter/zos/v1r11/index.jsp?topic=/com.ibm.zos.r11.idas200/modl.htm

and it happens that the manual example tells just what You are asking for

Hi

Just saw the documention is very nice, but unfortunately i don't have access to ISMF.

well... if You have the authority to change the managemnt class,
it is odd that You do not have access to ISMF

talk to Your support in order to have ISMF included in Your ISPF options

no reason for us to waste time because of Your organization bad setup

Also, I can't recall if the IDCAMS changes will reflect in migrated datasets, as I do recall running loads and loads of HSM FIXCDS commands to cater for migrated datasets.

I suppose you change the ACS routines to deal with this at recall time, but if the changes affect the longevity of the data, it would be a very good idea to check out wether the changes do affect the HSM CDS dataset contents.
