Alternate Configuration

Use this panel to work with Alternate Configurations. An Alternate Configuration is an object that the Network Configuration Assistant provides for TCP/IP technology.

Alternate Configurations represent alternate locations or LPARs where a z/OS image can be started. The stacks in an Alternate Configuration have the same configuration as their Base Configuration, except that symbol values can vary across Alternate Configurations. Alternate Configurations can be used for disaster recovery, planned outages, sandbox systems, or any other use.

Before you begin, decide on the values and settings that you want to specify in the steps below.

Steps:
  • Click Actions > New to define a new Alternate Configuration and indicate which images it contains. This list shows the images that can be moved to or restarted in the Alternate Configuration.
  • Click Actions > Copy to define a new Alternate Configuration that contains the same images as the selected Alternate Configuration; you can change the symbol values of the new Alternate Configuration.
  • Click Actions > Modify to change the selected Alternate Configuration name or comment line, and to change which images can be moved to or restarted in it.
  • Click Actions > Delete to remove the selected Alternate Configuration.
  • Click Actions > View Details to display the TCP/IP stack symbol values for each stack that can be started in the selected Alternate Configuration.
After you create an Alternate Configuration, you can modify Network Configuration Assistant system symbol values in the stacks that Alternate Configuration contains to give them different values for the Alternate Configuration. To change Alternate Configuration symbol values, take either of the following ways:
  • Click the Systems tab and select a stack. Select Actions > Stack symbols.
  • Click the Reusable Configuration tab. Select Actions > RC Symbols.

To add or remove an image from an Alternate Configuration, select the Alternate Configuration and click Actions > Modify, click Next, and check or clear the images that you want to modify on the Select Systems panel of the Modify Alternate Configuration wizard.

You have completed this panel when you have specified in the steps above the values and settings that you want.

You can also take the following actions:

  • Click Select a Technology to change technology perspective to configure policies.
  • Click Tools to select backing store actions.
