Resolving symbolic IP addresses

Resolving symbolic IP addresses

Overview

You can use option 4.2.2 to find out how symbolic IP addresses (canonical notation) are resolved. Name resolution is handled by the resolver of the z/OS system, for example, according to definitions in TCPIP.DATA.

Procedure

  1. In the "Service Manager Selection Menu", enter 4.2 to call the "OCF Application Control" selection menu:

    PEB4OCF ----------------------------------------------------------------------
    Option ===> __________________________________________________________________

    OCF Application Control Subsys-ID – Q93V
    Sysname - BETA

    1 LU 6.2 - Control LU 6.2 Applications

    2 TCP/IP - Control TCP/IP Applications












    Select one of the above options. Press END to return to the previous menu.

  2. Select option 2 to call the "TCP/IP Application Control" input panel.
  3. In the Action field, specify R for Resolve and type the symbolic IP address (canonical notation) in the IP‑Address field.
