Install the PBS software on the client nodes, repeating steps 1-3 above.
Configure the PBS nodes so that they know the server: Check that the file /var/spool/PBS/server_name contains the name of the PBS server (zeise in this example), and edit it if appropriate. Also make sure that this hostname resolves correctly (with or without the domain-name), otherwise the pbs_server may refuse connections from the qmgr command.
Create the file /var/spool/PBS/mom_priv/config on all PBS nodes (server and clients) with the contents:
# The central server must be listed:
$clienthost zeise
where the correct servername must replace "zeise". You may add other relevant lines as recommended in the manual, for example for restricting access and for logging:
$logevent 0x1ff
$restricted *.your.domain.name
(list the domain names that you want to give access).
For maintenance of the configuration file, we use rdist to duplicate /var/spool/PBS/mom_priv/config from the server to all PBS nodes.
Start the MOM mini-servers on both the server and the client nodes:
/usr/local/sbin/pbs_mom
or "/etc/rc.d/init.d/pbs start" on Linux. Make sure that MOM is started at boot time. See discussion under point 5.
On Compaq Tru64 UNIX 4.0E F there may be a problem with starting pbs_mom too soon. Some network problem makes pbs_mom report errors in an infinite loop, which fills up the logfiles' filesystem within a short time ! Several people told me that they don't have this problem, so it's not understood at present.
The following section is only relevant if you have this problem on Tru64 UNIX.
On Tru64 UNIX start pbs_mom from the last entry in /etc/inittab:
# Portable Batch System batch execution mini-server
pbsmom::once:/etc/rc.pbs > /dev/console 2>&1
The file /etc/rc.pbs delays the startup of pbs_mom:
#!/bin/sh
#
# Portable Batch System (PBS) startup
#
# On Digital UNIX, pbs_mom fills up the mom_logs directory
