[rules-users] Specifying time in date-effective

[Michael Anstis]

I am unfamiliar with the "date-effective" attribute so will not comment.

However, regarding getting a rule to run on a specified time every day, I
would suggest use of an external scheduler (Windows Task Scheduler, CRON,
Quartz etc) that invokes a process to trigger execution of the activations
on the agenda (i.e. fireAllRules) at the specified time every day. It is
important to remember that Rule activations are determined when Facts are
inserted into WorkingMemory. The activations collect on the agenda and are
executed when fireAllRules() is invoked. So you *could* perform your
WorkingMemory actions (insert, update, retract etc) throughout the day and
only trigger the resulting actions when you want.

If any of your Rules match temporal patterns you might be better moving to
5.1 and leveraging it's CEP facilities.

It is difficult to say much more without understanding what you are trying
to achieve.

With kind regards,

Mike
