I have attached a couple screenshots to indicate my issue trying to use cron from the Data Push setup in Integration Studio.
Basically I am trying to cause the Data Push to happen at a specified time within an hour, not at the top of the hour as it does by default, say 5 minutes after the hour.
I am unable to find information on exact syntax or actual working examples.
I am able to enter a syntax that initially the system indicates is valid (screenshot 1) and when I save the integration, I get an error (screenshot 2).
My guess is that I am not using the correct syntax, but I cannot find any information on the proper use of the cron function.
I have search Google and specifically on HP's site with no luck at all!
The cron expressions are found on page 370 of the HP uCMDB Modeling Guide:
A Cron Expression is a string composed of six or seven fields separated by
white space. Six of the fields are mandatory, and one is optional.
The following table contains the fields used in a Cron Expression.
