Hi All
I am using 4.0. I have a requirement to execute a rule only during a
specified time of a given day
While going through the documentation I found that I could use the
date-effective attribute to specify the date and time
6.5.1.8. date-effective
default value : N/A
type : String, which contains a Date/Time definition
A rule can only activate if the current date and time is after
date-effective attribute.
But while trying out the same, the engine recognizes only the day and
not the time. How do I specify the time? So far I have been using the
std format HH:MM:SS , tried both 12-hr and 24 -hr format but no luck.
Please help.
Also, I would like to know how can I make a rule run on a specified time
everyday. With date-effective specifying a date would be mandatory? Is
thr a way or I need to put that in the rule condition part.
Thanks
Devyani

Hi Devyani,
You might have problems with the date format due to your system's settings.
There's the following remark in Drools 4 documentation:
--
I believe, that date-effective will simply check the system time before
firing a rule and, if the current time is before the specified time in the
rule, it won't fire the rule.
AFAIK, you can't make a rule be triggered at a certain time everyday, except
if you insert at that specified time a fact (or a set of facts) that will
make that rule fire..

Date
The date format "dd-mmm-yyyy" is supported by default. You can customize
this by providing an alternative date format mask as a System property
("drools.dateformat" is the name of the property). If more control is
required, use the inline-eval constraint.
The best thing is to set that system property to the exact format you want
to use. Something like this:
System.setProperty("drools.dateformat", "dd-mmm-yyyy hh:mm");
4:13 a.m.
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
