Question
How can I interpret the Cron Expression in the Guardium Scheduled Jobs report ?
Cause
The Scheduled Job Cron Expression is shown as a list of characters and numbers - how can I relate that to a true schedule ?
Answer
The Scheduled Jobs report as in the below example lists a Cron Expression
Guardium Monitor -> Scheduled Jobs
The Operating System uses Cron Jobs to fire the specific jobs at the specified time(s) . Guardium uses the Quartz scheduler
For the example above, the elements listed delimited by spaces are interpreted as follows. ...
- 0 - leading 0 not used by Guardium at this time
- The other fields follow the standard cron expression
0 - The minute past the hour
5 - The hour
? - Day of the month
* - Month
1,2,3,4,5,6,7 - day(s) of the week
Note that * and ? mean "every"
So in that example we know that the Archive job is set to run at 5:00 am every day - as per the GUI Data Archive Schedule ..
Administration Console -> Data Management -> Data Archive -> Modify Schedule
A "/" it specifies increments - for example
"0/15" in the minutes field means "the minutes 0, 15, 30, and 45" ( ie 15 minute increments each hour starting at minute 0 )
Further information can be found here including further details on the special characters used
