Peter, SDSF has the “CSR” display (Common Storage Remaining) and on later releases you can even issue the “JCS” action (Job Common Storage) against a row on the CSR panel to drill down to each individual chunk of common storage (and browse it if you so wish).
For in-use common storage, see the SDSF “AS” display and you can use the “JCS” action against active jobs as well. SDSF also has the “CS” common that shows common storage summarized by subpool and key, and then the “L” action drills down to each block of storage within that subpool+key to show who owns it.

Is there any tool available in CBTTAPEA which can tell me or trace SQA users and who are not releasing the storage?
