The remotely callable procedure runs as an independent process, not as part of Sybase CEP Server. Run the RPC server on the same computer as the Sybase CEP Server, or on a different computer.
The RPC server can serve many different clients. Furthermore, the Sybase CEP Server, plugins, and CCL queries can be clients to several different RPC servers. One RPC server could check email for viruses, while another looks up historical stock information, and a third retrieves customer information.
You or a 3rd party can write the RPC server. You can write the RPC server in any language and are not limited to the languages thatSybase CEP provides SDKs for.
