Preparing to Start Your Product › Subsystem Identifier Setup

Subsystem Identifier Setup

The setup of your product environment usually requires the following subsystem identifier (SSID) values that were defined during the setup process:

• An SSID value for the subsystem identifier for the SOLVE SSI—The SOLVE SSI started task automatically identifies this SSID value to the system.
• An SSID value to enable the use of z/OS commands and messages—This SSID is named the AOM subsystem interface ID (AOM SSID). The product region started task automatically identifies this SSID value to the system.

If you want the SSID values to be set permanently and available at system IPL time, you can set them in the SYS1.PARMLIB(IEFSSNxx) member. If you use this member, ensure that you add the AOM SSID for the region first (after JES) in the list of subsystem names, because the first region listed in the SYS1.PARMLIB(IEFSSNxx) member controls the processing of messages by the subsystem interface.
