Install and Execute the Server

The server code interfaces with both TCP/IP and CA OPS/MVS facilities, and therefore both services must be active prior to server execution.

To install and execute the server

1. Make the OPVMSV server resident in a library containing REXX members that will be concatenated into filename SYSEXEC.
2. Prepare the JCL for a start-up Job or STC for the actual execution.
3. Use at least one global variable and optionally two to execute the cient/server application. If a rule exists for GLV security, the FIRELIMIT may need adjustment if set too low.
4. Start the OPVMJCL proclib member, which is in the SYS1.OPS.CNTL data set, using the MVS START command.

The server code executes using normal z/OS JCL conventions. It does use CA OPS/MVS services, and therefore must be associated with the appropriate OPS SSID.

Note: The sample OPVMJCL JCL includes the OPS$OPSx DD statement in case the default OPS SSID name is not appropriate. That statement should be removed or made into a comment if an override is not necessary. The sample member will need JCL modifications to comply with installation unique naming standards.
