About Siebel Gateway Name Server

The Siebel Gateway Name Server serves as the dynamic address registry for Siebel Servers and components. At start up, a Siebel Server within the Siebel Enterprise Server stores its network address in the Gateway Name Server's nonpersistent address registry.

Siebel Enterprise Server components query the Gateway Name Server address registry for Siebel Server availability and address information. When a Siebel Server shuts down, this information is cleared from the address registry.

The Gateway Name Server also includes a persistent file (siebns.dat) containing Siebel Server configuration information, including:

• Definitions and assignments of component groups and components
• Operational parameters
• Connectivity information

As this information changes, such as during the installation or configuration of a Siebel Server, it is written to the configuration file on the Name Server.

In a production environment, there can be only one Name Server installed per machine. Do not share the same Name Server for your development, test, and production environments.

Language Pack Installation. You do not need to install all the languages that your Siebel Deployment may run on the Siebel Gateway Name Server. However, the Siebel Gateway Name Server installation includes utilities used for Siebel Server administration. Siebel administrators only see some server administration error messages in the languages that have been installed on the Siebel Gateway Name Server.
