If you want to run something repetitively and are running unix, why not use cron to log into universe start the phantom and start your job? That way, you can control it based on the system time, rather than sleeping for 12 hours, which will not allow you to run at an explicit time.

Just be sure they're launched with the "PHANTOM" command and not directly from the uv environment, otherwise any 2 uv cron jobs that overlap will attempt to use the same shared memory segment. Also, cron processes don't execute /etc/profile or the particular cron user's profile from the home directory, so things like umask and any necessary environment variables have to be explicitly defined. Here's an example of a script that runs a uv phantom from cron: #!/bin/sh UV=`cat /.uvhome`/bin/uv umask 002 cd /uvdata/FABRIC.PROD $UV "PHANTOM PI0999" >/dev/null 2>&1 -John ------- u2-users mailing list [email protected] To unsubscribe please visit http://listserver.u2ug.org/ ------- u2-users mailing list [email protected] To unsubscribe please visit http://listserver.u2ug.org/
