Establishing local connections for SMA applications
After an application is linked to the Shared Memory Access (SMA) library, the application can establish a local connection directly to the SMA server, instead of over the network.
The connection request is initially sent over the network connection (handshake connection) by using any locally available protocol (TCP/IP, Named pipes, Unix pipes). During the connect handshake, the shared-memory segment handle is passed to the driver so that it can access the server shared memory.
If an SMA connect request is made to the server that is not an SMA server, a connect error is returned.
Important A single application can make only one local SMA connection to a server. However, the SMA application can make standard network-based connections to any local or remote server.
