Third-Party HTTP Load Balancer Rules

The variables in the following rules have the following meaning:

• enterprise is the Siebel Enterprise Server name.
• AOM is the Application Object Manager name.
• server is the Siebel Server name. You can change this element to the TCP/IP address of the Siebel Server, if desired.
• SCBroker_port is the port assigned to the Siebel Connection Broker on the Siebel Server.
• sid is the server ID of the Siebel Server. This server ID is a unique number assigned to each Siebel Server during initial configuration.

Component Rules

These rules are URLs for initial connection requests. The syntax of a component rule is as follows:

/enterprise/AOM/=server:SCBroker_port;...;

When the file is generated, a component rule is created for every enabled Application Object Manager found on every running Siebel Server.

Server Rules

These rules are URLs for server reconnection requests. The syntax of a server rule is as follows:

/enterprise/*/!sid.*=server:SCBroker_port;

The first asterisk in the syntax is a wildcard for the Application Object Manager. The exclamation point and dot-asterisk (.*) are wildcards that parse the server name to extract the Siebel Server ID.

Not all load balancers can handle a wildcard character (*) in the middle of the URL. In these cases, create URLs with the following format:

/enterprise/AOM/!sid.*=server:SCBroker_port;

Repeat this mapping for each combination of the Application Object Manager and Siebel Server ID.

Round-Robin Rules

These rules are URLs for server retry requests. The syntax for a round-robin rule is as follows:

/enterprise/AOM/RR=server:SCBroker_port;...;

This syntax is the same as that of component rules, except that RR is appended to the URL. This string alerts the load balancer to apply a round-robin rule that routes this request to a different Siebel Server.
