Siebel Gateway Server Connection Brokering and Resonate Central

Siebel Connection Brokering and Resonate Central.

What is Siebel Gateway Server Connection Brokering.

Connection Broker is a server component in Siebel which does intraserver load balancing, in other words it directs client connection requests to the least-laden Siebel Server operating the desired component, as a result it provides greater scalability and higher availability and thus results in performance improvement of the Siebel application.

Siebel Connection broker (SCBroker) has its own service running and it uses the Resonate Central Dispatch for distributing Web server connection requests across multiple Siebel Servers. To know more information about Siebel connection brokering and its concepts, please see “Implementing Load-Balancing with Central Dispatch” provided in Siebel Bookshelf.

Siebel Connection Broker (SCBroker) is always enabled by default and has several important parameters which are cited below.

PortNumber - Specifies the port number on which SCBroker listens. The default is 2321 which is specified during installation, but you can also change the port number later.

DfltTasks - Specifies the default number of processes for SCBroker. Recommended value is 2.

MaxTasks - Specifies the maximum number of processes for SCBroker. Recommended value is 2. This value cannot be less than DfltTasks and hence is dependent on it.

AutoRestart - Default is On. If there is a situation when SCBroker terminates abnormally, this setting allows it to restart the SCBroker automatically. As such, setting this parameter to Off or False is not recommended because it many lead to undesirable behavior.

ConnForwardAlgorithm. This algorithm is nothing but the routing scheme for SCBroker to use when routing intraserver requests to Application Object manager (AOM)  processes

What is Siebel Central Dispatch Scheduler?

The Central Dispatch Scheduler component determines which server to direct a request to by collecting current loading information from an agent component. It is recommended to install Central Dispatch on each Siebel Server on which you want to employ Siebel load balancing, and on any other machines and systems that will be dedicated for the Central Dispatch primary scheduler and backup scheduler.

For installation of please refer to "Installation Tasks for Central Dispatch" article on Oracle Support.
