Disable a platform to make it temporarily unavailable.
If you no longer require a platform, disable and discard it.
Before you begin
Before you discard a platform, you must first disable and
discard all the installed applications in the platform, but you do
not need to delete the application definitions (APPLDEF resources).
For instructions to disable and discard applications, see Disabling and discarding an application.
Before you discard
a platform, you must also shut down the CICS® regions
that are active in the platform. To shut down a CICS region, in the Regions view, right-click
the CICS region and select Shutdown.
Refresh the Regions view and confirm that the status of the region
is INACTIVE. Alternatively, shut down the CICS region using CICSPlex® SM or CICS commands.
You can disable a platform
while applications are still installed in the platform, and while CICS regions are active in the
platform.
About this task
When you disable or discard a platform, all the CICS bundles that were deployed
with the platform are also disabled or discarded. You can remove an
individual CICS bundle that
was deployed with the platform, without disabling or discarding the
platform. For instructions to do this, see Removing a CICS bundle from a platform.
Procedure
- Open the CICS Cloud
perspective. The Cloud Explorer view shows the current
status of the platform. If you also want to check the status of the CICS bundles for the platform in
the CICS regions, in the CICS Explorer® menu bar,
click to open the Bundles view.
- In the Cloud Explorer view, locate the installed platform
in the Platform hierarchy.
- To disable the platform, right-click the platform name
and select Disable, then click OK to
confirm. CICSPlex SM
disables the CICS bundles for
the platform in the CICS regions,
and disables the platform. Refresh the Cloud Explorer view, and check
the platform status. If a status other than Disabled is shown for
the platform, see Checking the status of a platform for
more information and suggested actions.
- To discard the platform, you must disable it first, as
described in Step 3. You must also disable and discard all the installed
applications, as described in Disabling and discarding an application,
and shut down all the CICS regions
that are active in the platform. When the platform is disabled, all
the installed applications are discarded, and the CICS regions are shut down, right-click the
platform name and select Discard, then click OK to
confirm. CICSPlex SM
discards the CICS bundles for
the platform in the CICS regions,
and discards the platform. When you refresh the Cloud Explorer view,
instead of the platform name, you see the name of the platform definition
(PLATDEF). The Platform hierarchy no longer displays the applications
that were installed in the platform, but the application definitions
(APPLDEF) can be found in the Application hierarchy.
Results
The platform is disabled or discarded, and all CICS bundles that were installed with the platform
bundle are also disabled or discarded.
