Hi Gurus,
sorry if this is off topic.
in ksh, Is there any way to tell when each job run in the background have
completed if you are running 9 jobs at a time in the background?
I am writing 3 ksh scripts to run about 300 jobs but im stuck on one part
of the code.
basically i have the 3 main scripts which each readsits own list of
commands to run from a command_list file.
because of license issues I can only run 9 jobs at a time, so i am trying
to always have 9 jobs running at a time, no less or more than 9. If i run
more than 9 the jobs fails and moves on to the next one which will keep
failing until a license is available, and i only have 9 licenses.
The jobs all take different amount of times to complete.
I was trying to setup a loop to run the commands in the background and
count each job as it starts and finishes, but i realised i cant tell when
they finish if i run them in the background.
Is there any way to tell when jobs run in the background have completed?
That would solve my issue.
Here is the code I have so far, this is a sample of one the main jobs, i
have 3 sets of this main job and all 3 main jobs together cannot run more
than 9 jobs total at a time. If all 3 are running at the same time i would
like them to each run 3 at a time, but if 2 of the main jobs finish, i
would like the remaining one to start running 9 at a time so they each will
finish as fast as possible.
RUNREPORTS1 ()
{
OLDIFS=$IFS
IFS="
"
REPORTFILE=`cat /tmp/report_list`
for X in $REPORTFILE
do
ksh ". /etc/profile; $X &"
# This is the part of the code where I need help figuring out when a job in
the background is done, so i can count the # im running.
done
IFS=$OLDIFS
}
Here is a sample of the report_list1 file:
/data/bin/reporter -m MYCO -D $DATE -c"YTD:SDSL" -s 01/01/1997
/data/bin/reporter -m MYCO902 -D $DATE -c"YTD:JFDKL" -s 01/01/1997
/data/bin/reporter -m MYCO3 -D $DATE -c"YTD:WEL" -s 01/01/1997
/data/bin/reporternew -m MYCO884 -D $DATE -c"YTD:JYUKL" -s 01/01/1997
/data/bin/reporternew -m MYCO5 -D $DATE -c"YTD:JDFKL" -s 01/01/1997
/data/bin/reporterX -m MYCO6 -D $DATE -c"YTD:JZXKL" -s 01/01/1997
/data/bin/reporterX -m MYCO234 -D $DATE -c"YTD:JBVKL" -s 01/01/1997
/data/bin/reporternew -m MYCO8 -D $DATE -c"YTD:JKXCL" -s 01/01/1997
/data/bin/reporter -m MYCO65 -D $DATE -c"YTD:JKLKL" -s 01/01/1997
/data/bin/reporter -m MYCO234 -D $DATE -c"YTD:JOOKL" -s 01/01/1997

this goes on for over 300 unique commands
thank you in advance!
