As part of datasets cleanup, we are in the process of deleting huge number of datasets.
I am planning to have all the datasets in one ps number with delete command and give as input to IDCAMS step as below.
//STEP01 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD DSN=INPUTDATASET,DISP=SHR
//
Here INPUTDATASET is a ps file having all the datasets with delete command.
ex: DELETE BXMD.DEXTZ.V.MSA.SORTDA10.VEN
DELETE BXMD.DEXTZ.V.MSA.SORTDA11.VEN
I am aware that it works for number like 5000 around. Is there any number limit for IDCAMS "DELETE" Command? |

What happened when you tried it for yourself.
Hardly a difficult thing to do is it. Of course you might have considered using Dfdss instead of IDCAMS as this has great wildcard and filtering capabilities and also offers the option of performing a backup before deletion. |

Hello,
Yes - it is also known as adrdssu.
There are several topics in the forum that have adrdssu/dfdss processes.
Suggest you speak with your storage management people before just deleting thousands of datasets. . . |

Suspect IDCAMS has a limit of 4096 statements in a single execution, and not just deletes. But if you're at later releases of ZOS (maybe 1.11 or 1.12 up) you can use masks in the dataset names which means you could reduce the number of statements required.
DFDSS DUMP with DELETE to a DUMMY DD is a good alternative but it won't handle datasets migrated by DFHSM. |
