Creating a subsystem description

You can create a subsystem description in two ways. You can copy an existing subsystem description and change it, or you can create an entirely new description.

The following are two approaches that you can use:
  1. To copy an existing subsystem description, using the character-based interface, use the following instructions:
    1. Create a Duplicate Object (CRTDUPOBJ) of an existing subsystem description. (You can also use the Work with Objects (WRKOBJ) or Work with Objects using Programming Development Manager (WRKOBJPDM) commands.)
    2. Change the copy of the subsystem description so that it functions in the manner that you require.
      For example, you need to remove the job queue entry because it identifies the job queue that the original subsystem uses. Then you need to create a new job queue entry that specifies the parameters that the new subsystem uses.

      Remember to review the autostart job entries, the workstation entries, the prestart job entries, and the communication entries, and verify that there are no conflicts between the two subsystems. For example, verify that the workstation entries do not cause both subsystems to allocate the same display devices.

  2. To create an entirely new subsystem description, use the character-based interface and use the following instructions:
    1. Create a Subsystem Description (CRTSBSD).
    2. Create a Job Description (CRTJOBD).
    3. Create a Class (CRTCLS) for Add Prestart Job Entry (ADDPJE) and Add Routing Entry (ADDRTGE).
    4. Add Work Entries to the subsystem description.
      • Add Workstation Entry (ADDWSE )
      • Add Job Queue Entry (ADDJOBQE)
      • Add Communications Entry (ADDCMNE)
      • Add Autostart Job Entry (ADDAJE)
      • Add Prestart Job Entry (ADDPJE)
    5. Add Routing Entries (ADDRTGE) to the subsystem description.
