Registering the 4-tuples

You can register 4-tuples in any of the following ways.

  • You can register all the 4-tuples in the CICS® ONC RPC data set that are defined with YES specified for Register from Data Set. To do this, select option 1 on panel DFHRP03, and press Enter. After these 4-tuples have been registered, panel DFHRP03 is still displayed, so you can make other selections.
  • You can register 4-tuple definitions one at a time. To do this, you use option 3 or option 4 on panel DFHRP03. Make changes, if you need any, to panels DFHRP5 and DFHRP5B and get them validated as described in Defining the attributes of a 4-tuple. To register the definition, press Enter.
  • You can register 4-tuples from a list. See Working with a list of 4-tuples.
  • When CICS ONC RPC is disabled, you can register all the 4-tuples in the CICS ONC RPC data set that have YES for their Register from Data Set attribute by initiating automatic enable processing.
When a 4-tuple is registered, two things happen:
  • If the program-version-protocol 3-tuple has not yet been registered with TCP/IP for MVS™, it is registered. The Portmapper assigns a port number to this combination, and that port number is the one that clients use to request the service represented by this 4-tuple. Procedure 0 for the program, version, and protocol becomes available to callers.
  • The resources associated with the 4-tuple become available to service client requests. When a client request arrives in CICS ONC RPC, the resources used to service it are those of the 4-tuple whose program, version, and procedure numbers match those of the request, and whose protocol matches the protocol used to transmit the request from the client to the server.
