Thierry,
Here I try giving you answer with my test example...
1) I ran a test job (as below)
J E S 2 J O B L O G -- S Y S T E M 1 X 0 1 --
N O D
05.25.48 JOB00596 ---- THURSDAY, 17 JUN 2010 ----
05.25.48 JOB00596 IRR010I USERID NBKEODV IS ASSIGNED TO THIS
JOB.

TIME=05.25.52
05.25.52 JOB00596 $HASP395 NBKEODVA
ENDED
------ JES2 JOB STATISTICS ------
17 JUN 2010 JOB EXECUTION DATE
Job came in input queue(conversion/reader time) at 05:25:28 & started
executing at 05:25:52 (executiong queue)
now since I had above example as my good friend SMF ..processed it with
SAS/MXG and found 05:25:48 is a Job initiation time.
I selected TYPE30_1 which is for job initiation time and it surely had
05:25:48 ..
this is a description for the JINITTIME
JINTTIME NUM 8 DATETIME21.2 JOB*INITIATE*TIME
Job initiate time stamp. There can be multiple initiations of a job,
and this may be the first, last, or an in-between initiation event.
What I also found the gap between the Job initiation time and the Readtime
is shown in the variable RDRTM(Reader time) which is a gap between the
Initiation and real execution...
Here's the output I had :
OBS SYSTEM ZDATE JINTTIME JOB
RDRTM READTIME
1 1X01 17JUN2010 17JUN2010:05:25:48.82 NBKEODVA
0:00:01.94 17JUN2010:05:25:46.84
Now back to the solution :-
If you see substantial gap between the values of job initiation and
execution..Bet look at the $D PERFDATA which has various parameter it can
tell you where we are having delay..certainly IBM can also help you in
tuning your JES configuration...MAS configuration has good impact on
performance if not good tuning.
