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.

iSeries Navigator

To use iSeries™ Navigator to monitor the number of subsystems that are using a memory pool, follow the following instructions:

1. In iSeries Navigator, expand My Connections > connection > Work Management > Memory Pools > Active Pools or Shared 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.
