nrglbd(8ncs)

Name

nrglbd − Non-Replicating Global Location Broker Daemon

Syntax

/etc/ncs/nrglbd [ −version ]

Description

The Global Location Broker (GLB), enables clients to locate servers on a network or internet. The GLB database stores the locations (that is, the network addresses and port numbers) where server processes are running. The GLB maintains this database and provides access to it.

The /etc/ncs/nrglbd daemon should run as a background process. It requires no options or arguments. A Local Location Broker daemon ( llbd ) must be running on the local host when nrglbd is started.

You can run only one nrglbd on a network or internet.

On ULTRIX systems, nrglbd is typically started by a line in /etc/rc such as the following:

/etc/ncs/nrglbd& echo -n ’ nrglbd’ > /dev/console

Options

−version Display the version of the Network Computing Kernel (NCK) that this nrglbd belongs to but do not start the daemon. (NCK is part of the Network Computing System (NCS) on which DECrpc is based.)

Restrictions

This section discusses the procedure to follow if the system running the nrglbd is taken off-line.

If you restart nrglbd on the same system and no server on any other system changed state, all things should run as before. If, however, an application tries to contact a server that is no longer running or which has different port numbers, the application will fail. The application also will not see any new server registrations.

If a copy of /etc/ncs/glbdbase.dat is not available, you must create an up to date version of the file before restarting nrglbd. To do so, use lb_admin to query the llbd for registration data on every system running an DECrpcserver and then use lb_admin to register all DECrpc servers with the GLB on the new host. Then restart nrglbd.
