Windows: Configuring server and client communications

After installing the server, you can set up client and server communications by specifying options in the server and client options files.

About this task

Set these server options before you start the server. When you start the server, the new options go into effect. If you modify any server options after starting the server, you must stop and restart the server to activate the updated options.

Review the server options file (dsmserv.opt.smp) that is located in the server instance directory to view and specify server communications options. By default, the server uses the TCP/IP and Named Pipes communication methods.

Tip: If you start the server console and see warning messages that a protocol could not be used by the server, either the protocol is not installed or the settings do not match the Windows protocol settings.

For a client to use a protocol that is enabled on the server, the client options file must contain corresponding values for communication options. In the server options file, you can view the values for each protocol.

You can specify one or more of the following communication methods:
  • TCP/IP Version 4 or Version 6
  • Named Pipes
  • Shared memory
  • Secure Sockets Layer (SSL)
    Tip: You can authenticate passwords with the LDAP directory server, or authenticate passwords with the server. Passwords that are authenticated with the LDAP directory server can provide enhanced system security.
