We've been running WebObjects apps with wotaskd+JavaMonitor on Amazon Linux for
several years. I didn't jump on your thread from mid-July ("Auto restart of
wotaskd in Linux") only because we don't have a solution to that specific
problem—admittedly our deployment setup is fairly modest, but I've never seen a
crashed wotaskd (that I can recall). I tested it at the time, and certainly
killing wotaskd on a fresh appserver instance didn't re-spawn a new one—it's
just not a problem we've needed to solve, so I had nothing to add for you.
Our appservers certainly do survive reboots, though, so I'll described the
setup briefly here. (We only run "standalone" appservers where JavaMonitor
monitors wotaskd on the same host, nothing with app instances distributed over
more than one host.) We have a very simple initialisation script (with '#
chkconfig: - 90 20') that starts (and stops and restarts) wotaskd and
JavaMonitor (minimally modified from the script that was posted to the mailing
list years ago, and is probably still available via the wiki) installed as
/etc/init.d/webobjects, and at appserver creation time we run:
chkconfig --add webobjects
chkconfig webobjects on
/etc/init.d/webobjects start
And that's pretty much it. That should start wotaskd+JavaMonitor at appserver
creation time, and re-start it on reboot. Any app instances running prior to
reboot should also be re-started after reboot.
