Methods of Communicating

Different communicating methods suit different scenarios.

The platform server clients interface communicates with the platform server started task in one of the following three ways.
  • Through cross memory communication using PC calls
  • Through SNA communications
  • Through TCP communications using IP address or IP name

The most efficient method of communicating with the platform server address space is through cross memory calls. If you are running on the same mainframe as the platform server, it is good practice that you use cross memory communication method.

The least efficient method is communicating with the platform server through TCP using an IP name, because each connection request requires us to issue a DNS call to get the IP address for the platform server. If you are running on a different mainframe than the platform server, you can use either SNA or TCP to communicate with the platform server.
Note: Use the IP name option only if the IP address of the platform server is dynamically defined and changes.
