Issue/Introduction

How is the CRON syntax used with the Scheduler for PCF product?

Resolution

The Scheduler for PCF syntax for specifying schedules is a variation on the Quartz CRON format. The main variations are the lack of support for both Seconds and Year in the schedule expression. All expressions must be 5 segments delimited by a space: MIN HOUR DAY-OF-MONTH MONTH DAY-OF-WEEK.

Note:

• CRON syntax does not support the Seconds or Years column
• Either the Day-of-Month or Day-of-Week must contain a “?”
• You must add a space after the last wildcard and the closing double quote (")

For example, to run a Scheduler job every hour at the top of the hour:

cf schedule-job test "0 * ? * * "
Scheduling job test for spring-music to execute based on expression 0 * ? * *  in org cf-support / space pivotal as [email protected]
OK
