Siebel Deployment Planning Guide > Siebel Architecture Overview > About the Siebel GatewayThe Siebel Gateway provides the dynamic address registry for Siebel Servers and server components, and also for Siebel Application Interface and other modules, like Siebel Enterprise Cache and Siebel Constraint Engine. For example, at startup, Siebel Server within the Siebel Enterprise Server stores its network address in the Siebel Gateway's nonpersistent address registry. Siebel Enterprise Server components query the Siebel Gateway registry for Siebel Server availability and address information. When a Siebel Server shuts down, this information is cleared from the registry. The Siebel Application Interface and Siebel Gateway work together to provide Siebel Server load balancing. When a user requests a new application connection, Siebel Application Interface sends a request to Siebel Gateway, which returns a connect string for the least-loaded Application Object Manager from among the Siebel Servers supporting that component. The user session will use this Application Object Manager. The Siebel Gateway also includes persistent storage in the registry for configuration information for Siebel Server, Siebel Application Interface, and other installable components. This information includes:
As this configuration information changes, such as during the configuration of Siebel Enterprise, a Siebel Server, or a Siebel Application Interface, this data is written to the Siebel Gateway registry. There can be only one Siebel Gateway, or one Siebel Gateway cluster, installed and configured for each environment in which you have created a Siebel Enterprise. Further, you cannot share the same Siebel Gateway across development, test, and production environments. As of Siebel CRM 18.5 Update, Siebel CRM supports an optional native clustering feature for Siebel Gateway, to provide high availability benefits to Siebel CRM customers. For more information, see Defining High Availability Policies. For information about installation and configuration tasks associated with Siebel Gateway, see the Siebel Installation Guide for the operating system you are using. It is strongly recommended to install the same set of languages on each server computer in your Siebel Enterprise Server. For more information, see the Siebel Installation Guide for the operating system you are using. See also Siebel Global Deployment Guide.
