Installing a new application to a CICS system

Introduce a new application, which has been provided in one or more data sets, into a running CICS system without affecting continuous availability.

About this task

  • The application has been provided in one or more PDS or PDSE data set. The application could be a third party (vendor) product that is provided as a set of application artifacts in one or more PDS or PDSE data set or a new in-house application.
  • You cannot restart CICS at this time, to apply the fix.
  • The person who performs the action has the appropriate access authorization.

Procedure

  1. Define a LIBRARY resource that includes the data set or data sets containing the new application.
    Typically, the application will have no intersects with any existing LIBRARY resources and can use the default ranking value.
    Use one of the following methods to define the LIBRARY resource:
    • The Business Application Services (BAS) component of CICSPlex® SM.
    • The CICS® resource management transaction CEDA.
    • The CICS offline CSD utility program DFHCSDUP.
    • The EXEC CICS CREATE LIBRARY command.
    • The CICS Explorer®.
    You can use the CICS Explorer to define a LIBRARY resource in a single CICS region, or in the data repository for the CICSplex, or in a CICS bundle. For information about the management of resources defined in CICS bundles, see Characteristics of bundled resources.
  2. If you did not use EXEC CICS CREATE to define the LIBRARY, install the new LIBRARY resource using CEDA, the CICSPlex SM WUI, or the CICS Explorer.
  3. Define to CICS the programs, and map sets that make up the application and transaction definition or definitions that reference it.
  4. Install the programs and other definitions.

Results

The new application is installed in the CICS production system and continuous availability is maintained.
