How do subsystem definitions and fixed/variable memory pool allocations effect system performance? Should we have no fixed memory allocations?
Subsystem allocations for memory pools should be based on what the individual subsystem jobs are doing, how much priority those jobs have and how much memory is required for those jobs. If you have a limited number of local printers, the subsystem should be fixed. Heavy communications subsystems may also be set to fixed. As far as your system having fixed memory allocations, it would be dependant on hardware, software and how this particular AS/400-iSeries system is being used. You can read about how to set up your sysems from the work management guide. The link can be found at the Knowledge Links page.
