Determining the number of subsystems using a memory pool

Subsystems are allocated a certain percentage of memory to run jobs. It is important to know how many different subsystems are pulling from the same memory pool. After you know how many subsystems are submitting jobs to a pool and how many jobs are running in a pool, you might want to reduce resource contention by adjusting the size and activity level of the pool.

To monitor the number of subsystems that are using a memory pool, follow the following instructions:
  1. Expand Work Management > Memory Pools > Active Memory Pools or Shared Memory Pools.
  2. Right-click the memory pool that you want to work with and click Subsystems.

    From this window you can determine the number of subsystems that are using an individual memory to run their jobs.
