TCP/IP port sharing enables requests for work to be shared between several Gateway daemons through a single TCP/IP port. Port sharing provides TCP/IP load balancing in a single LPAR.
When connections are established between a Client application and a Gateway daemon, the TCP/IP port sharing component of the z/OS® TCP/IP Communications subsystem distributes requests across multiple Gateway daemons. When the connection is established, subsequent requests from the Client application continue to use the same connection.
TCP/IP port sharing is included in Scenario SC03.
