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