The Begin action initiates the CICS logical unit of work (LUW). Any CICS program executions must take place between an LUW Begin action and a commit or Rollback action.

The commit action ends the logical unit of work (LUW) and permanently commits any changes to the queue.

The destroyPart action destroys the part and its children, and releases all associated resources. You can use this action for both visual and nonvisual parts. All connections to the destroyed part are removed.

The Rollback action ends the logical unit of work (LUW) and cancels any changes made, returning the database to its state before the LUW.
