msgbserv

compute host locking server More...

SYNOPSIS

msgbserv [-port PORT] [-roport ROPORT] [-pid]

DESCRIPTION

The msgbserv deamon program provides the locking service of compute hosts for the exclusive use of compute hosts. The locking status can be observed in realtime by the msgb(1) program.

SCOREHOSTS.DB

In the scorehosts.db(5) file, the host records of the compute hosts required to be used exclusively must have the msgb attribute associated with the hostname where the msgbserv is running. When the scout(1) and msgblock(1) programs find the msgb attribute in the scorehosts.db file, then these commands try to lock the compute hosts where these commands will use.

The msgserv opens two TCP ports, one for locking and another for observation.

OPTION

-port PORT

Specifying the locking port number.

-roport PORT

Specifying the observation (read-only) port number.

-pid

When specified, the msgbserv will output PID when it daemonizes itself.
