Setting Cron Start Conditions
Use
You set cron start conditions for a job definition when you want jobs to run once or periodically on a day relative to the start/end of the month. With cron start conditions, you define the minute, the hour, the day of week and/ or month, and the year when you want the job to run.
Prerequisites
Steps Select Job and Set Task Properties of the Add Task Wizard are complete. For more information, see Creating a Scheduler Task.
Procedure
1. Choose the Cron tab.
2. In the Details section, define the job’s schedule by entering values for the fields.
Each field has a possible range of the values it can take, as specified in the table below:
Field |
Possible Value |
Year |
2006 – infinity |
Month |
0 – 11. 0 stands for January. |
Day of month |
1 – 31 |
Day of week |
1 – 7. 1 stands for Sunday, 2 – for Monday, and so on. |
Hour |
0 – 23 |
Minute |
0 – 59 |
For more information about the possible values in each of the fields and the rules that apply to those values, see the Field Ranges and Operators sections in Scheduling Jobs with Cron Start Conditions.
3. In the Time Zone field, enter a time zone.
4. Choose Add to add the cron start conditions to the scheduler task.
5. Repeat the procedure to add more cron start conditions to the scheduler task.
Result
An entry for the cron start conditions is displayed in the Cron Time Table.
Now, you can:
● Set recurring start conditions for the job definition
● Set simple start conditions for the job definition
● Save the scheduler task by finishing the Add Task Wizard. See Creating a Scheduler Task.
