[INUG-Users] Using PAD to control other processes.

Then you are almost there! The trick is to add the part that traps
SIGTERM (and any other signals you want to watch for) and have the
script kill the process. As you may have seen posted in the last
coupled of days, PAD issues a SIGTERM (15) to a managed process, and if
it doesn't exit then it eventually issues a "kill -9."

I already have something like that invoked every 5 minutes by cron. The
Event Enablement script is called ee_start. Its start a process call
'ihstdmai'. My cron job does a ps and grep for ihstdmai and runs the
ee_start script if it doesn't see the process. The problem with this is
my cron job is for user ncoadmin not root. and Event Enablement
requires root. However, for some reason, its still starts up.
I wanted to implement this using PAD and not use cron since my ever
benevolent Unix SAs let PAD start stuff as root. I do not have root
priveleges, however am given a few trivial sudo commands. With EE
running under PAD , its like I have root since I can start and stop a
root owned process.
Thanks,
Joe

Joe,
In this case, you need to write a script that starts EE. Then have it
troll "ps" output now and then (via sleep loop) to see if EE is still
running and restart it if not. When it gets a SIGTERM, it should stop
EE. Now you have made it "PAD-aware". You can be as clever as you
want.
Then you have PAD start the script instead of EE. Common trick. I am
not at liberty to post my script, but I bet someone else might be
willing to post theirs. Or you might search the archives; I think I
have seen some script examples posted in the past, using a lot less code
that I do...
Jacob, do you know any volunteers who might write a "how to put
something that doesn't know about PAD under PAD" document for the INUG
Web site?

I tried it and PAD starts EE successfully, but never gets the PID. So
nco_pa_status always shows 'Pending' with PID of '0' and the PA log show
PA continually trying to restart it.

No reason you can't. :)
