Hi,
Using Rexx, is there any way i can get the CPU usage thats is displayed in the "Display Active" panel of SDSF. Basically i want to get the CPU usage of different LPAR's in my site from one of the LPAR.

Other than REXX is also fine for me..

Hi,

Suggest you get in touch with System Support group at your site, they must be having this kind of report in place already.

I agree with Anuj. Also not sure what you mean by CPU usage. Overall utilization at a given time? Use by a particular job or set of jobs? cumulative use? Number of processors in service? Unlikely this can be done from Rexx directly but if SDSF shows it, you can use Rexx to get it from SDSF. See the SDSF books for version 1.9 or later for a Rexx command interface to SDSF.

Unless you are from system capacity team -- I wonder why do you want to know CPU usage (?) for an entire LPAR.

Being an application engineer, my concerns are limited to CPU used by a particular job or set of jobs as semigeezer has said. Smile

As far as I know, there is no relationship between CPU usage and the availability of an initiator. Availability depends upon current work load and the assignments of the various job classes to the initiators at any given moment. In addidition, some shops change the "job class-to-initiator" assignments at the end of normal business hours anyway. I'd suggest some other method of attempting to have your job run sooner. Is this a test or production job?

If you are looking for initiators, there are probably Rexx execs around that look for that information. I know I've written them in the past and probably published some in some newsgroup or other. Other people have as well. Of course, you need to be able to run that on another system and that would normally require an initiator, so that would defeat the purpose here. If you have access to the initiator list in SDSF, use that.

Just be sure that you always submit the job in the job class you are authorized to use for your type of job or you could get people complaining.
