Define a System Image

You can use express setup to define a system image to your region automatically or you can build one manually.

To define a system image manually

  1. Enter /RADMIN.I at the prompt.

    The System Image List panel appears. This panel lists the system images defined to your system.

  2. Press F4 (Add).

    The System Image Definition panel appears.

  3. Specify the name of the system image, the version number, and a short description of the system image.

    One system image is required for each region. If you are defining a system image for a subordinate, use the name assigned during the multisystem linking process.

  4. Press F3 (File).

    The System Image List appears and a message appears indicating that the system image has been successfully added to the knowledge base.

Define a System Image Using Express Setup

Express setup defines a system image to your region at installation; however, you can use express setup at any time to build a new system image. Express setup discovers resources and nodes automatically.

Note: The time taken to complete this process is determined by your site's configuration.

To define a system image using express setup

  1. Enter /RADMIN.AD.I at the prompt.

    The Automation Services : Confirm Express Setup panel appears.

  2. Specify values in the System Image and Version fields.

    These default to the local z/OS system name and the next available version number.

  3. Configure the $RMEXPR6 control member. Perform the following steps:
    1. Copy dsnpref.NMC1.CC2DEXEC($RMEXPR6) into dsnpref.rname.TESTEXEC.
    2. Update the dsnpref.rname.TESTEXEC($RMEXPR6) specifications. For example, comment out the resources you do not need to discover.
    3. Rename $RMEXPR6 and use this in the Control Member field.

      The $RMEXPR6 Control Member defaults to discover all of your resources.

  4. Set Load Image? to YES.

    This system image is loaded after the discovery has completed.

  5. Set the Create Application Name Definitions? field to YES.

    Application name definitions are automatically created for each address space discovered.

  6. Press F6 (Action).

    The Automation Services : Express Setup Status panel appears. This panel reports the progress of the resource discovery and the number of resources successfully discovered.
