Adaptive Server acts as the client when it connects to another server to execute a remote procedure call (RPC) as shown in Figure 14-2.
Figure 14-2: Adaptive Server acting as client to execute an RPC
One physical connection is established between the two servers. The servers use the physical connection to establish one or more logical connections—one logical connection for each RPC.
Adaptive Server 11.5 and later supports two security models for RPCs: security model A and security model B.
