Internal mode

In this mode, at the predefined time, the Control-D monitor switches to SUSPENDed status and then internally activates the NEWDAY processes.

The Control-D monitors SUSPEND mode means that no new missions will be activated. The monitors do not wait until the decollation missions that are being processed are finished, but the primary monitor does wait until all active backup, migration, and restore missions are finished. The primary monitor also signals the Printers Control monitor to suspend all active printing missions, and waits until the monitor does this.

To run the New Day procedure in internal mode

1. Start the Control-D monitor by issuing one of the following operator commands:

   S CONTROLD

   S CONTROLD,NDAYMODE=INT

   At the predefined time, the following message is issued on the operator console:

   CTD12AI CONTROL-D MONITOR IS SUSPENDING FOR A NEW DAY

   When all processes are suspended (excluding the decollation), the following message is issued on the operator console:

   CTD12CI CONTROL-D MONITOR SUSPENDED

   The primary Control-D monitor activates the special subtask CTDNDAY, which is the first stage of New Day process, after all Control-D monitors are suspended. This subtask compares the date and time of the computer with the Control-D control files. If they do not match, the following questions are issued on the operator console:

   CTD426W CONTROL-D (CTDNDAY) DID NOT RUN FOR nnnnnn DAYS

   CTD427W IS THIS TRUE? (ANSWER "YES" OR "NO")

   CTD428W YOUR ANSWER IS:

   Answer these questions according to the following recommendations:

   • If the date and time do not match, and the computer has not been operational for a some time (for example, after a hardware failure or a holiday), you must respond YES.
   • If there was no specific reason for the date and time not to match, the computer was probably started with the wrong date. In this case, respond NO, check and if necessary correct the system date, and then restart the Control-D monitor.
   • If the system date was correct, the INCONTROL administrator must determine the cause of the problem.
   • If the subtask terminates, abends, or fails for any reason, a highlighted, unrollable message is issued on the operator console and the monitor shuts down after the all active decollation missions finish executing.

   The CTDNDAY subtask includes the following steps:

   • formatting the Active Mission and Active Transfer Files
   • deleting unneeded missions from Active Mission File
   • ordering missions according to mission lists.

   Line CTM34F in the program list separates the first and second stages of the New Day process.

   The following message is issued on the operator console after the NEWDAY subtask finishes executing:

   CTD12CI CONTROL-D MONITOR RESUMED

2. The Control-D monitor starts the CTDNDAY task, which performs the second stage of the New Day process, with the following command:

   S CTDNDAY,NDAYMODE=INT

3. If this procedure terminates with nonzero return code, or abends or fails for any reason, the INCONTROL administrator must determine the cause of the problem and then restart the CTDNDAY task with the following command:

   S CTDNDAY,NDAYMODE=INT

   After Control-D starts the CTDNDAY task, the monitor resumes processing of all missions and signals the Printers Control monitor to resume all suspended print missions.
