CHAPTER 5 Setting Up Communications Across the Network
Configuration Guide 53
A client’s interfaces file does not need a master line. It functions correctly with
only a query line.
If your site has
multiple installations If you have more than one Adaptive Server installation, each server’s interfaces
file should contain information about all servers on the network.
If all of your server products are running on the same platform, you can create
one master interfaces file and copy that file to each machine. For more
information, see “Creating a master interfaces file” on page 58.
If the host machine supports multiple networks, see “Configuring interfaces
files for multiple networks” on page 59.
Heterogeneous and homogeneous environments
You can run Adaptive Server and clients on the same platform or on different
platforms.
If the platforms are different, each platform may require a different format and
configuration for its interfaces file. Figure 5-1 illustrates how a PC client uses
network information in its interfaces file (sql.ini) to connect to Adaptive Server
running under UNIX, and how Adaptive Server uses its interfaces file to
connect to another server during a remote procedure call.
