Offline reorganization using UCF

Reorganization can be done using a single program, called the Utility Control Facility (UCF), or by using various combinations of utilities.

When UCF is used, it acts as a controller, determining which of the various reorganization utilities need to be executed and then getting them executed. Using UCF reduces the number of JCL statements you must create and eliminates the need to sequence the various utilities for execution. It also reduces the number of decisions operations people must make.
