Hello,

Submitted jobs run in address spaces called partitions or initiators.

Hi Dick,
Just curious, can you provide an example, also can the class of the batch job relate which address space its running, again an example would be helpful.
Thanks
Nimesh

Hello,

For an example, talk with your scheduling, operations, or system support people - they can show how your system is defined.

Yes, different classes are assigned to different partitions/initiators. This will also be visable when you see your system definition.

Hello,

There is no "utility" (other than JES itself) that i'm aware of to determine where jobs run - if you clarify what you want to know, i'll try to provide more info. . .

Your system has a list of job classes (among some other things) that determine where your job will run. Your job may have a CLASS= parameter coded or the class may be automatically assigned by the system.

If your system requires it, you may have to include the CLASS parameter on your job cards. Your scheduling or system support people can tell you what classes are defined for which usage on your system.

To add to Dick's reply......

Our shop for example provides different job classes (which is coded in "CLASS=" parameter ). So if we have small job to run (expected CPU time less than 5 secs)..we use CLASS=3......more than 5 secs ..but less than 10 secs CLASS=4 and .....longer jobs...CLASS=5.

Hence shops define these parameters for you and you shud know what to use when.
