I'm sure someone here can help - can you go into more detail about what your prob is? Are you trying to schedule shutdowns/restarts, or are you scheduling some other job that is conflicting with shutdowns/restarts, or something else?0 -

I am trying to schedule a job while shutdown/restart in RHEL 5.0 -

Okay, try this for starters. Create a test script, i'll call it "job", that takes "stop" as an argument, and put it in /etc/rc.d/init.d/ (or /etc/init.d/). Have it do something simple, like write something to a log: e.g.#!/bin/sh stop(){ echo $0 > /tmp/job.log } case $1 in stop) stop ;; *) esac exit 0
Make it executable:chmod 0755 /etc/rc.d/init.d/job
Make a "kill" symlink for it in /etc/rc.d/rc6.d:ln -s /etc/rc.d/init.d/job /etc/rc.d/rc6.d/K99job
the "K" in the beginning of the link name indicates that the script will be called with the "stop" arg when the system reboots/halts. The number after the K is the order in which it will get executed (1 = first, 99 = last).
IMPORTANT: there must be a file (can be empty) in /var/lock/subsys with the same name as your init script (job). so before testing, do this:touch /var/lock/subsys/job
Ideally, this file should get created when your job first gets started. Or if there is no such job already running, you can put this in /etc/rc.d/rc.local, and will get created every time the system comes up.0 -
Awesome, this is solid help.
Thanks!0
