How Adaptive Server IQ makes connections

The network search involves a search over one or more of the protocols that Adaptive Server IQ supports. For each protocol, the network library starts a single port. All connections over that protocol at any one time use a single port.

You can specify a set of network communication parameters for each network port in the argument to the CommLinks parameter. Since these parameters are used only when the port first starts, the interface library ignores any connection parameters specified in CommLinks for a part already started.

Each attempt to locate a server (the local attempt and the attempt for each network port) involves two steps. First, the interfaces library looks in the server name cache to see if a server of that name is available. Second, it uses the available connection parameters to attempt a connection.

The default server is the first one started on a machine. This server gains use of the shared memory port.
