Disabling and discarding an application

Disable an application to make it temporarily unavailable on a platform. If you need to install a new version of an application, or if you no longer require the application, disable and discard it.

About this task

When you disable or discard an application, the CICS® bundles that are deployed as part of the application are also disabled or discarded in the CICS regions. When you want to install a new version of an application, you must also replace the application definition with a new application definition that points to the new version of the application. You cannot edit an application definition that has been installed.

Procedure

  1. Open the CICS Cloud perspective. The Cloud Explorer view shows the current status of the application. If you also want to check the status of the CICS bundles for the application in the CICS regions, in the CICS Explorer® menu bar, click Window > Show View > Other > CICS SM Operations > Bundles to open the Bundles view.
  2. In the Cloud Explorer view, locate the installed application in either the Platform hierarchy or the Application hierarchy.
  3. To disable the application, right-click the application name and select Disable, then click OK to confirm. CICSPlex® SM disables the CICS bundles for the application in the CICS regions, so that the application is no longer available on the platform. Refresh the Cloud Explorer view, and check the application status. If a status other than Disabled is shown for the application, see Checking the status of an application for more information and suggested actions.
  4. To discard the application, you must disable it first, as described in Step 3. When the application is disabled, right-click the application name and select Discard, then click OK to confirm. CICSPlex SM discards the CICS bundles for the application in the CICS regions, and uninstalls the application from the platform. When you refresh the Cloud Explorer view, instead of the application name, you see the name of the application definition (APPLDEF resource). If CICSPlex SM fails to disable or discard any of the bundles, the application is not discarded.

Results

The application is disabled or discarded, and all CICS bundles that are part of the application are disabled or discarded. The application definition remains in the data repository for the CICSplex.
