Steps for configuring the rpcbind address space

The rpcbind software supplies client programs with the universal addresses of RPC server programs.

Before you begin

The z/OS® rpcbind server supports the portmapper binding protocol (RPC Binding Protocol Version 2) as well as other RPC binding protocols. This means you can run rpcbind instead of portmapper. Portmapper and rpcbind cannot be run at the same time, because they both listen on /etc/services sunrpc port 111.

About this task

RPC server applications do not have well-known port numbers. Instead, they obtain an ephemeral port number, create a universal address, and register that address with rpcbind. Clients contact server programs by obtaining the universal address of the server from rpcbind, and sending messages to the universal address of the server.

Procedure

Perform the following steps to configure the rpcbind address space.

  1. Configure the PROFILE.TCPIP data set for rpcbind.
  2. Configure security server (or RACF® equivalent) items.
  3. Update the RPCBIND cataloged procedure.
  4. Update the /etc/services file.
  5. Configure SYS1.PARMLIB for rpcbind.
