That is my preferred method. Build a script that is run at a specific time
or time and day that kicks off a U2 process. Not necessarily starting a
phantom but starting any regularly run process on UniVerse. If you restart
your system you don't have to remember to restart separate phantoms, the
cron starts automatically. I think you can do the same thing in Windows
using the Windows scheduler but since I have never used U2 on Windows I
could be wrong.

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.

Is Unix crontab the preferred method to run phantom processes in UV?
Thanks.

That's what I've always used for phantoms that need to repeatedly run on
a set schedule. 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
