If that graphic is correct, part of the problem is all the jobs in QPGMR are running *BASE and dollars to donuts there is not enough memory in there and the activity level is not set correctly. This system needs someone who knows work management to tune it. Also it's a reasonable guess that most everything else is running in *BASE as well.

Step one: create at least one shared pools, (wrkshrpool) and set one up for this batch, use *INTERACT for the interactive subsystem
CHGSHRPOOL POOL(*SHRPOOL15)
SIZE(1500) (pick a number here that makes sense)
ACTLVL(18)
PAGING(*CALC)
I picked pool 15 because its most likely not used. If shared pool 1 is not in use, change that to 1.

Step two: Change the subsystem QPGMR with the following command:
CHGSBSD SBSD(QPGMR) POOLS((2 *SHRPOOL15))

Step three: (the one most people miss) Change the routing step to move the jobs into the second subsystem memory pool
CHGRTGE SBSD(QPGMR)
SEQNBR(9999)
POOLID(2)

Now all the new jobs will run in *SHRPOOL15. You can set the memory as needed.

It's not a very active subsystem: it's one of twelve jobs in a subsystem
that says it will take a maximum of 17.

From the "Work With Subsystems" display:

Opt Subsystem Storage (M) 1 2
QPGMR .00 2 2
