TCPPORT

The TCPPORT option specifies the port number on which the server TCP/IP communication driver waits for requests for client sessions. The server TCP/IP communication driver listens on this port for both TCP/IP and SSL-enabled sessions from the client.

Using different port numbers for the options TCPPORT and TCPADMINPORT enables you to create one set of firewall rules for client sessions and another set for other session types (administrative sessions, server-to-server sessions, storage agent sessions, library client sessions, managed server sessions, and event server sessions). If the two port numbers are different, separate threads are used to service client sessions and the other session types. If you allow the two options to use the same port number (by default or by explicitly setting them to the same port number), a single server thread is used to service all session requests.

SSL-enabled client sessions that use the TCPPORT option have the same limitations as the SSLTCPPORT option. The following types of sessions do not use SSL:
  • Network Data Management Protocol (NDMP)
  • Automated Cartridge System Library Software (ACSLS)
  • Database restore operations
If the ADMINONCLIENTPORT option is set to NO, SSL-enabled sessions for the administrative client require that different port numbers are specified for the TCPADMINPORT and TCPPORT options.

If you specify the same port number for both the SSLTCPPORT and TCPPORT options, only SSL connections are accepted and TCP/IP connections are disabled for the port.

Windows operating systemsYou can change this option with the SETOPT command. When you change a port, the IBM Spectrum Protect server starts listening on the new port immediately. All current connections remain in use until closed.
