The PORTMAP address space runs the Portmapper function.
Portmapper is the software that supplies client programs with the
port numbers of server programs.
About this task
Clients contact server programs by sending messages to port
numbers where receiving processes receive the message. Because you
make requests to the port number of a server rather than directly
to a server program, client programs need a way to find the port number
of the server programs that they want to call. Portmapper standardizes
the way clients locate the port number of the server programs supported
on a network.
Procedure
Perform the following steps to configure PORTMAP:
- Specify AUTOLOG and PORT statements in hlq.PROFILE.TCPIP.
- Update the PORTMAP cataloged procedure.
- Define the data set for well-known procedure names.
