Clients and servers communicate through a connection. For a client application to connect to a server application, the server application must be listening for the client connection request.
Making a connection from Open Client
Use the DSQUERY environment variable to determine the name of the target server.
Uses the sql.ini file or a directory service to obtain the address of the target server.
Open Client uses DSQUERY only if
the Open Client application does not specify the name of the server.
Listening for a request in Open Server
Use the DSLISTEN environment variable to determine the name of the Open Server application.
Use the sql.ini file or a directory service to obtain the Open Server application’s address.
Use DSLISTEN only
if the Open Server application does not specify a server during
initialization.
