Set up the JES3 Interface

The JES3 command support is separate from the z/OS console support. The IATUX18 exit controls JES3 commands that are issued at JES3 RJP consoles. The subsystem interface (SSI) handles JES3 commands issued on z/OS consoles. If you have no JES3 RJP consoles, then IATUX18 provides no additional support.

CA OPS/MVS interfaces with JES3 for intercepting commands through the standard JES3 IATUX18 exit mechanism. The CA OPS/MVS exit code is a module (OPJS18PR) that you can link-edit with your existing IATUX18 load module. The created load module, named IATUX18, contains both the user exit and the CA OPS/MVS exit, with the CA OPS/MVS exit entered first during JES3 execution.
