To configure schedule date and time

  1. Select Run At.

    Clear the checkbox if you do not want to configure the command to run at a specific date and time, and proceed to Step 5.

  2. Select the Month in which you want the command to run by doing one of the following:

    • To choose a particular month, use the dropdown menu to select the desired month in which you want the command to run.

    • To have the command run every month, either use the dropdown menu and select Every Month, or leave the field empty.

  3. Select the Day you want the command to run by doing one of the following:

    • To choose a particular day of the week, use the dropdown menu to select the day.

    • To choose a particular date, use the dropdown menu to select the desired day of the month (1-31).

    • To choose the last day of the month, use the dropdown menu and select End of Month.

    • To have the task run every day, either use the dropdown menu and select Every Day, or leave the field empty.

  4. Select the Time you want the command to run by doing one of the following:

    • To choose a particular time of day, select Time of Day, and enter the time you want the command to be run.

    • To have the task run every hour, select Every Hour at, and enter the minutes past the hour in the Minute field. The command will run every 60 minutes at the specified number of minutes past the hour.

  5. Optional: Select Repeat Every to run the command periodically.

    1. Enter the hour in the Hour field.

    2. Enter the minutes past the hour in the Minute field.

      For example, if 1 is entered in the Hour field, and 30 is entered in the Minute field, then the command runs every 1.5 hours. If 0 is entered in the Hour field, and 30 is entered in the Minute field, then the command runs every 30 minutes.

      If the specified interval in minutes is a factor of 60 (for example, 1, 2, 5, 6, 10, etc.), the first execution will be at a time that permits execution at the start of the hour. For instance, if the current time is 02:53, and the repeat scheduled interval is five minutes, the first execution is at 02:55.

  6. Select Accept to accept the scheduling configurations.

    Caution: These execution times are local time, so care must be taken for periods when daylight savings time starts and ends. If jobs must only be run once per day, avoid scheduling them in the changeover hour. In many locations, requests that are specified to run at times between 02:00 AM and 03:00 AM on the second Sunday in March do not execute because of the change to Daylights Savings Time (DST). Requests that are specified to run at times between 01:00 AM and 02:00 AM on the first Sunday in November execute twice.

    In instances where the execution time matches DST, an alarm is generated to warn you of a potential issue. If you want to specify the number of days before the DST that an alarm is raised, use the "Jsh.json" file.

    The following file example uses the default values:

    "JSH": {

    "Alert1": 30,

    "Alert2": 5,

    "Alert3": 1,

    "Time": "12:00:00"

    }

    Where:

    • "Alert1", "Alert2", and "Alert3" are the three alarms that you can configure. These alarms can be configured for different values with a maximum of 60 days before the DST. If the alarms are configured with the same alert value, only the alarms with different values will be displayed.

    • "Time" is the specified hour during the day when this process is executed and the alarm is generated. It only runs once a day.
