Automatic Shared Memory Protocol for Local Connections on Windows

A c-tree TCP/IP client library compiled on the Microsoft Windows OS now supports automatically switching to the shared memory protocol when the specified server is running on the same system as the client and the server is configured to use the shared memory protocol. Shared memory offers greatly enhanced performance for local connections on the same physical machine, sometimes up to five times the speed of TCP/IP. For communications intensive applications, this can offer a significant performance boost.

The FairCom DB Monitor utility will display the communications protocol associated with each connection. The FairCom DB administration utility, ctadmn, has also been updated to display either SQL_TCPIP or SQL_SHAREMM depending on which protocol the SQL client is using. In addition, support for terminating FairCom DB SQL clients (both TCP/IP and shared memory clients) is available in both the FairCom DB Monitor utility and the ctadmn utility.
