Finding the datasets with highest space allocation.

Post by ShilpiSRE » Mon Jan 29, 2018 6:44 pm

Hi,

In this new project of ours I have observed that they are not using RLSE parameter in the SPACE parameter and it looks like that many datasets are allocated a lot of space. I have manually looked at some of the datasets and they have a more than 100 cylinders allocated for primary and secondary quantity.

Is there a way I can identify and create a list of such datasets?

DCOLLECT can tell you. ISPF 3.4 data set lists can be printed out. Disk management packages, if installed at your site, can tell you.

Thanks Robert after posting my question I got a JCL on DCOLLECT but it asks for the Storage Groups. If we don't know the storage groups, can we do it with the Production high level qualifiers of he datasets?

Your storage support group will be able to tell you what your storage group names are.
