Minimum Sockets per Port Setting

When a Web Agent starts, it opens the number of sockets specified by the MinSocketsPerPort parameter in the Host Configuration Object on the Policy Server. These sockets maintain a constant connection to the Policy Server.

For most types of web servers (including Apache-based servers in worker mode), we recommend leaving this parameter at its default setting. Increasing this parameter occupies additional sockets unnecessarily by leaving them open even when the Web Agent is not receiving any requests for resources.

Note: For multiprocess web servers (such as an Apache-based server in pre-fork mode), you can reduce this number of sockets to one. Because each process uses only a single thread to communicate with the SiteMinder Policy Server, only one socket is required.
