Re: QUSRJOBI - Cpu Percentage Usage for individual jobs

When you say "CPU Percentage" I assume that you mean something like the
"CPU%" field of WRKACTJOB?   If not, you'll need to clarify what you mean.

WRKACTJOB's CPU percentage is based on a time interval.  It's the
percentage of the total CPU used since the last time you pressed F10 or
since the first time you ran WRKACTJOB.

Therefore, in order to get the same results as WRKACTJOB, you have to
choose a starting time for the CPU interval and at that time call QUSRJOBI
with format JOBI1000.  Then, at the end of the interval, call with
JOBI1000 again to get the percentage over the time that has elapsed.

First of all, nothing in QUSRJOBI is a total for the system.  It's always
per-job, as this is a per-job API.

At *offset* 80 of JOBI0200 is the processing time used (which is different
from CPU percentage) And at *offset* 84 is the number of auxiliary I/O
requests (which is VERY different from CPU percentage)

Please make sure you understand the difference between an offset and a
position.  An offset is always one lower than the position.  So offset 80
is position 81.


I could just write the code to do this and post it for you to read, but
from the way you're asking your questions, it's clear that you don't
understand what's going on -- so I'll try to explain it instead:

The first thing that you MUST do if you're going to successfully use this
API without someone else writing the code for you is to read the manual
page for the API.  Since you know the name of the API is QUSRJOBI, you can
use the API finder to get it to it.  The API finder is here:

http://publib.boulder.ibm.com/iseries/v5r2/ic2924/info/apis/apifinder.htm

Under "Search by Name" type QUSRJOBI and click "Go!".  The system will
return a link to a manual page for that API.

One of the first things on the manual page is a listing of the parameters
that have to be passed to the API.  (And please remember that "Binary(4)"
is "10I 0" in RPG!  People frequently get that wrong.)   Also pay
attention to "optional parameter 2" since it's how you reset the
performance statistics (like pressing F10 in WRKACTJOB)

Then it explains the authorities that you need, and goes on to give more
detail on the what the different parameters mean.  Under the "Format Name"
parameter it gives an overview of what the possible formats are.  Since
you're interested in performance statistics, you can see here that
JOBI1000 is the format that you're looking for.

After the parms are detailed, it gives another overview about the
different formats, and then goes into the specific details.  Since you
know that you want JOBI1000, scroll down to the space where it says (in
bigger, bold letters) "JOBI1000 Format".

There will be a table here showing the different offsets, data types and
field names for JOBI1000.  In particular, you want to look at offset 104.
Remember, offset 104 is positions 105-108.   Since it's a "Binary(4)"
field, you want to define your RPG field as "10I 0".

Hope that helps...
