Initialization function overview

The Fast Path/EP initialization function lets you initialize a VSAM cluster that will be used for a DEDB in the same manner as the IBM DEDB Initialization Utility.

A database must have allocated space and must be empty before you invoke the INITIALIZE command. The initialization function can be performed offline only.

Fast Path/EP change and reload functions automatically initialize the area (if required) before writing any segments to it. If a failure occurs after initialization is complete, the area still is initialized. You do not have to restart processing at the initialization phase.
