zCX Support combined LFAREA usage (2G/1M) if not enough LFAREA is available within one type

Currently, zCX supports the use of LFAREA. This reduces the overhead for TLB and increases performance for zCX. If zCX is configured to use LFAREA and there is not enough LFAREA available within one range (2GB, 1MB) then zCX falls back to 4K what ...

Support JESLOG parameter on job card with the master subsystem

We execute our Netview STCs under the master subsystem rather than under JES2 and they can stay up for months at a time. The JESMSGLG can grow to several million lines which consumes a non-insignificant amount of spool space. We don't need that in...

Enhance the S, F and L line commands to work with hidden lines

The 'S', 'F' and 'L' line commands are used to reshow hidden lines, and can only be entered on lines that are not displayed ***and*** not hidden. It would be very useful if "doubled" ("SS", "FF" and "LL") versions could be used on the lines immedi...

Operlog should write more than a single MDB to a logblock to allow connecting of multiple MDBS for long multi-line messages

Filemode HSM - allow user to switch to su when issuing hbackup commands

it appears that if I am a user who can go into su (superuser) and then issue the hbackup command it doesn't honor or check the requestors ability to go to “su” (Facility class BPX.SUPERUSER). So…unless I have full access to all the files I want to...
