Integrating with z/VM Systems › Establish Communication

Establish Communication

For CA OPS/MVS to communicate with a z/VM system, you must set up the OPVMSV server on the z/OS system and the OPVMCL client on the z/VM system. The z/VM system must have an application that supports REXX sockets (for example, CA VM:Operator).

Note: This topic provides an overview of how to establish communication between CA OPS/MVS and z/VM systems. For detailed information, see the Administration Guide.

To set up the OPVMSV server on the z/OS system

1. Set the following parameters in the OPVMSV member of the data set allocated with the SYSEXEC ddname:

   zosipaddr

   Specifies the address of the z/OS system.

   zosipport

   Defines the port of the server.

   Customize other parameters as required.

   The server is configured.

2. Customize the OPVMJCL member in the CNTL data set.

   The server started task or job is configured.

3. Execute the OPVMJCL member.

   The server starts and can communicate with the clients.

To set up the OPVMCL client on a z/VM system

1. Customize the OPSMCL member of the CA OPS/MVS REXX data set:
   • Set zosipaddr and zosipport to the same values as for the OPVMSV member.
   • Set zvmtargetid to the z/VM user ID for the application that will communicate with CA OPS/MVS.

   Customize other parameters as required.

   The client is configured.

2. Transfer the customized OPSMCL member to a read-only minidisk on the z/VM system.
3. Define a z/VM user directory entry for the client with the following requirements:
   • Set MACHINE to ESA.
   • Set storage size to at least 8 MB.
   • Ensure the user has access to the minidisk used in Step 2.
4. Execute OPSMCL.

   The client starts and can communicate with the server.
