Establish Network Connectivity

To initiate the OPSHMC program, you must establish connectivity between the z/OS system and the LAN (either 802.5 token ring or Ethernet) that contains the SE/HMC workstation. This connection lets the SE/HMC API communicate with the SE/HMC through SNMP.

This connectivity allows TCP/IP connectivity between CA OPS/MVS and the SE/HMC workstation. Installing and configuring such a TCP/IP connection requires some communications knowledge and expertise and should be handled by your LAN administrator. In addition, you may want to discuss this with your hardware vendor systems engineer. A successful ping of the SE/HMC workstation from a TSO/E session verifies that TCP/IP connectivity is established. For successful operation of OPSHMC, you must also verify that IP ports 161, 162, and 3161 are not blocked by any router in the network path or firewall software.

Note: For information about how to configure the SE/HMC to use the API, see the IBM System z Application Programming Interfaces manual.
