Healthcheck for CPU consuming remaining USS subprocess

There is no internal instrument of the operating system which detects and terminates processes as described in the use case. We received a user modified health check which solves the described lack. It would be good if it becomes part of the offic...

Provide a SETOMVS SYNTAXCHECK equivalent via a batch job.

Request a batch utility which would allow you to check BPXPRMxx syntax via a DD for input and route the output to a DD. The benefits would be: (1) Allow any location for input (vs. current SETOMVS SYNTAXCHECK which must come from PARMLIB) and (2) ...
