This section describes the parameters that you can use to specify when to execute a project. For instructions on creating a schedule, see Scheduling Jobs.
Schedule entries in the system work like UNIX/Linux cron jobs, allowing you to use a series of fields to specify when a project executes.
Field |
Description |
Range |
---|---|---|
Minutes |
The number of minutes. |
0-59 |
Hours |
The hour in the day. |
0-23 |
Dates (Day of Month) |
The day of the month. |
1-31 |
Months |
The month of the year. |
1-12 |
Days (Weekday) |
The day of the week (Sunday = 0). |
0-6 |
The numeric values you enter in the fields may be represented as follows:
Use an asterisk (*) to denote all valid values in the range. An asterisk can be followed by a forward slash (/) and a step value. For example, a value of */2 in the Hours field executes the project every 2 hours.
Use a range of numbers separated by a hyphen. For example, 8-11 in the Hours field specifies hours 8, 9, 10 and 11. A range can be followed by a forward slash (/) and a step value. For example, 0-23/2 in the Hours field executes the project every other hour.
Use a comma-separated list of a set of numbers (or ranges) separated by commas. For example, 1, 2, 3-5, 8.
The project schedule is constructed from the values specified for the fields. In general, the project runs at the time or times that match all the fields as shown in the following examples:
Values Desired schedule |

However, if the dates and days fields are both non-asterisk values, then the project runs when either of them occurs:
