If the change of frequency is meant to be temporary, such as for testing purposes, use the PATCH command to reset the frequency to its original value when testing is over. To accomplish this, use the PATCH command in the following manner:
  • For SMS volumes:
            PATCH .MCVT.+418 X'0000C4E0' /* Reset the SMS automatic backup  */
                                         /* processing interval to its      */
                                         /* original 14 hour day.           */
  • For non-SMS volumes:
            PATCH .MCVT.+48C X'0000C4E0' /* Reset the non-SMS automatic     */
                                         /* backup processing interval to   */
                                         /* its original 14 hour day.       */
