  • Faux pas when creating a new Subsystem?

    I've found plenty of documentation for HOW to create a new subsytem on the IBM-i. I'm just wondering... what could go wrong?

    Can I have other subsystems use the the memory pool of the new subsytem when it's not being used?

    If you define a specific number for the amount of memory for a pool in a subsystem description then that memory is allocated only for that subsystem and cannot be used by other subsystems while the subsystem is active. When the subsystem is ended the memory goes back into the *BASE pool.

    If you define the subsystem pool to use a shared memory pool (*BASE, *INTERACT, *SHRPOOL1 - 60), then any subsystem that also uses the same shared memory pool can share the memory. When the subsystem is ended the memory stays in the shared memory pool.
