We have a 3 system plex, with two of those systems, DEV and PROD, in a
JES2 MAS. We had an incident recently where a development job got into
a loop and used up all spool. This in turn, caused our PROD system to
come to, basically, a screeching halt.
Management wants to investigate removing
If you are interested in not splitting, besides the mention of setting a line
limit, look at the emergency subsystem available in jes2 2.4. And of course
looking at potential automation to detect/ prevent issue may have value.
Although a job in a loop can be a challenge to handle.

Yes, a JES2 cold start with newly defined/allocated spool and checkpoint
datasets will be needed. Have you looked into setting default estimates in
JES2PARM, bytes, lines, pages, with OPT=1 to cancel jobs that exceed your
limits?

Food for thought - separate MAS for each environment, but same
SYSPLEX. Though better to have each environment in separate SYSPLEX
and MAS. (That also allows better separation for implementing
changes to each environment.

The easiest option would be to create a new environment and volume(s)
for test and development and IPL to the new volume(s), leaving the
production alone, and disable some volumes if you need to reclaim
space.
