Richard,

You don't really need another subsystem. What you need to do is add
another subsystem memory pool. Steps are:
CHGSHRPOOL POOL(*SHRPOOL12)
SIZE(3000)
ACTLVL(10)
PAGING(*CALC)
TEXT('For my Java Jobs')
Pick a shared pool, size, and activity level (number of jobs that will
be active at once) that makes sense to you.
Add the memory to the subsystem in question. I picked QBATCH, use the
correct one for you.

Jim, the only issue I've had with shared pools is that the system wants to tune them. I fI want a completely autonomous pool, I tend to add it to the subsystem itself, like this:

CHGSBSD SBSD(JVMSBS) POOLS((1 128000 10))

The system won't try to change the size on me. I'm not sure this is the best approach for the OP, but I find that especially in the case of Java it really helps to segregate the paging. JVMs and IBM i paging don't coexist very well, it seems.
