How Adaptive Server determines which directory service entry to use

Servers also need network information. When a server starts up, it looks in its interfaces file to determine where to listen for client connection requests. In addition, Adaptive Server can take on a client role when it makes remote procedure calls to other Adaptive Servers.

Table 5-1 shows where to find more information on server and client interfaces file tasks and topics.

How Adaptive Server determines which directory service entry to use

Adaptive Server uses directory services to determine the address at which it should listen for clients. When you start Adaptive Server, it performs the following steps:

1It looks for the server name supplied in the command line -soption. If the server name is not supplied in the command line:

2It determines its own name by checking the value of the DSLISTEN environment variable. If the DSLISTEN environment variable is not set, then it assumes that the server name is SYBASE.
