• Use the CL commands CRTJRN (Create Journal), CRTJRNRCV (Create Journal Receiver) and STRJRNPF (Journal Physical File) to prepare for using commitment control, and the CL commands STRCMTCTL (Start Commitment Control) and ENDCMTCTL (End Commitment Control) to notify the system when you want to start and end commitment control. See the CL Reference for information on these commands.
• Specify commitment control on the file-description specifications of the files you want under commitment control.
• Use the COMMIT operation code to apply a group of changes to files under commitment control, or use the ROLLBACK operation code to eliminate the pending group of changes to files under commitment control.
