Figure 5-1: Establishing network connections in a heterogeneous
environment
If both a client and a server are running under UNIX, the same interfaces file
is valid for both. Figure 5-2 illustrates how clients and Adaptive Servers
running in a homogeneous environment can use copies of the interfaces file to
establish connections. Because the two Adaptive Servers are running under the
same operating system, they can use the same interfaces file or exact copies of
the same file.
