Working with platforms

To set up a platform where you can deploy applications, you create and deploy a CICS® Platform project, and use a platform definition to install the platform in a CICSplex. You can troubleshoot, modify, or discard an installed platform.

Before you create a new CICS Platform project, you must set up a platform home directory in zFS. For instructions to do this, see Preparing zFS for platforms.

  • Creating a CICS Platform project
    A CICS Platform project defines a platform bundle, which is a type of management bundle that describes a platform. The platform bundle specifies the region types for the platform.
  • The platform descriptor editor
    Use the platform descriptor editor to work with platform bundles that are not yet installed in a CICSplex. If you do edit a platform bundle for a platform that is already installed, you must stop, discard, reinstall, and restart the platform to implement the changes.
  • Deploying a CICS Platform project
    Export the CICS Platform project to z/OS® UNIX and create a platform definition in the CICSPlex® SM data repository. Set up CICS regions to match each CICS region definition that you created in your platform.
  • Installing a platform definition and enabling the platform
    When you install a platform definition, the platform is created in the CICSplex.
  • Checking the status of a platform
    The status information for a platform shows whether the platform is active, and whether the CICS bundles for the platform are present and enabled in the CICS regions for the platform.
  • Diagnosing platform deployment errors
    If you experience any errors when attempting to create a platform definition or install a platform, follow this procedure to diagnose the problem and take suitable action.
  • Diagnosing platform runtime errors
    If your platform is not enabled, or if you experience any errors when attempting to update or change a platform, follow this procedure to take appropriate action.
  • Adding a CICS region to a region type
    Add more CICS regions to a region type to scale up the capacity of an active platform. You can also share CICS regions that are already part of a platform between multiple region types in the platform, to modify your platform’s architecture.
  • Removing a CICS region from a region type
    Remove a CICS region from a platform to scale down the capacity of an active platform. You can also remove shared CICS regions from any region types in the platform where they are no longer required, to modify your platform’s architecture.
  • Disabling and discarding a platform
    Disable a platform to make it temporarily unavailable. If you no longer require a platform, disable and discard it.
