HFZS subsystem requirements for deletion of migrated tightly-coupled associated dump data sets

Deletion of migrated tightly-coupled associated dump data sets is performed via a spawned BPX batch region. This is done to avoid potential performance issues.

The HFZS subsystem creates, and subsequently deletes, a "dummy" file in the path determined in the following order:

Specified via the HFZJLIB DD statement (for details, see Specifying an HFZJLIB DD statement).
The OMVS segment home path for the HFZS subsystem user ID (see OMVS home path).
/tmp

If unsuccessful in using any of these paths, message HFZ0192I is issued.
