Adaptive Server can communicate with other Adaptive Servers, Open Server applications, and client software across a network. Clients can communicate with one or more servers, and servers can communicate with other servers via remote procedure calls.
This chapter provides information about the connection process, the kinds of connections, and how to configure Adaptive Server to use sql.ini file connections.
For instructions on using Server Config to change the values that it can access, see “Configuring Adaptive Server”. For information on LDAP, see Chapter 5, “Lightweight Directory Access Protocol in Adaptive Server.”
Adaptive Server on Windows NT supports network connections using the Named Pipes, Sockets (TCP/IP), and IPX/SPX protocols. The default Adaptive Server uses TCP/IP and Named Pipes, since Named Pipes is always installed with Windows NT.
Two files control how clients find servers and drivers:
The sql.ini file lists the server names, their network addresses, and the Net-Library driver to use to establish a connection.
The library file, libtcl.cfg, lists the installed Net-Library drivers that are available to support each protocol (connection).
These files, which reside on both server and client machines, enable each Sybase product to find the other Sybase servers that are on the network. The installation program automatically creates, verifies, and appends these configuration files when you install Adaptive Server.
