Tidying up the LIBRARY configuration

Tidy up LIBRARY concatenations that have been used to apply temporary fixes or that contain application that are no longer used.

Before you begin

  • CICS is running.

Procedure

  1. Study the names of LIBRARY resources installed in CICS and the audit log of LIBRARY changes, to discover any LIBRARY resources used to apply temporary fixes that are no longer required, or LIBRARY resources for applications that are no longer used.
  2. Discard any LIBRARY resources that are no longer required.
  3. Delete the definitions of these LIBRARY resources, unless you believe that they will be required in the future and operational procedures allow reuse of LIBRARY definitions in this way.

Results

CICS continues as before. The set of LIBRARY resources installed in the CICS system are only those that are required for current applications used in the system.
