What is reorganization?

Reorganization is required when CICS® notifies CICS VR that an error occurred during a backout attempt, where the error was because the system is running out of space.

Reorganization replaces the data sets by redefining them with more space, or a larger index record space. The reorganization process can be run manually, or automatically as part of the Automatic Recovery feature, as described in Automated Recovery and Reorganization.

In addition, reorganization jobs can be initiated from the panel interface. For further information, see Running CICS VR reorganization the CICS VR User's Guide.
