Setting Up Communications
Across the Network
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.
Directory services contains information about the network locations of
servers. Directory services contain entries for all Adaptive Servers,
Backup Servers, and other server products on the network.
In the Sybase client/server environment, a client can connect with
Adaptive Server if it knows where the server resides on the network and
if the server supports the client’s language or character set. When a client
initiates a connection, it looks in its directory services for the network
location of the target server.
Directory services list the name and address of every server, including
Backup Server, Monitor Server, and XP Server. When you are using a
client program, and you want to connect with a particular server, the client
program looks up the server name in the directory services and connects
to that server.
