Topology Considerations for Session Communications
Generally, Siebel Communications Server components for session communications, such as CommSessionMgr, should be run on the same Siebel Server machines as those running AOMs. In some cases, however, you must run CommSessionMgr on a different machine than the AOMs. These options are described in detail below.
CTI middleware generally runs on servers located at each contact center facility.
Running CommSessionMgr on AOM Machines
Generally, Siebel Communications Server components for session communications should be run on the same Siebel Server machines as those running AOMs. Such a topology allows the AOM load-balancing mechanism to indirectly balance Communications Server load. CommSessionMgr loads are fairly light and do not, in themselves, present a reason to run this component on dedicated machines.
Set the Enable Communication parameter to TRUE for all AOMs to which your agents will connect. If you are using Siebel Server load balancing, then all AOMs to which requests are distributed should be configured the same way.
Running CommSessionMgr on Dedicated Machines
Sometimes you must run CommSessionMgr on a different machine than the AOM components.
CommSessionMgr must run on the same machine where the communications driver for your CTI middleware is running. If your driver requires a particular operating system platform, then you must install Siebel Server and run CommSessionMgr on a machine of this platform. (Communications drivers are required to be able to run on one of the supported Siebel Server platforms, as described in System Requirements and Supported Platforms on Siebel SupportWeb.)
If your AOM components (Call Center Object Manager) run on machines using a different platform, then you set several parameters in the communications configuration, including CommSessionMgr and RequestServer, in order to designate the machine where CommSessionMgr is running. All communications session requests from an AOM supporting users for this communications configuration will be routed to the CommSessionMgr component on the dedicated machine.
