Memory and CPU are two different things. If a job is taking 50% of the CPU, that means that half of the CPW of your machine is being used by that job. It does not mean your job is taking 50% of the memory.

memory pools
1)using WRKACTJOB, + F11 (or print the wrkactjob) you can see the type of job and what memory pool it is running out of. 2)then use DSPSYSSTS + F11 ( or print it) to see what Pool is used: 3)in the attached example, jobs of TYPE:BCH are running out of both memory pools 2(*BASE) and 3(*SHRPOOL3) 4)you need to look at Subsystem discriptions and job descriptions to start seeing where jobs are defined to run in memory pools.

memory pools
what memory pool does batch run out of? i'm seeing on one of our system that certain batch jobs are getting 50% of the cpu but is that total cpu or 50% of the memory pool its assigned to? i'm leaning to the latter because our interactive users are running slow right now. how would i possible fix this problem?Comment
