Hi,I'm using Drools 5.3.0. I've a proprietary key-value based data store, where
all the events are stored. As soon as an event is received, it is inserted in the session
and the rules (example below) is fired:
rule "registration count"no-loopdialect "mvel"when $e : Event(type ==
"registration", $s: student)then $s.registerCount += 1; update($s);end
All the 'registration' events which has occurred in the past (stored in data
store) also are inserted in session so that any rule with temporal operator (relates among
the events) can work fine. If I insert previous events then the rule "registration
count" is evaluated again for each previous events and fired. Please let me know, if
there is a way to prevent rule evaluation for certain rules while event insertion. The
events are too many, so I don't keep all in working memory for long period, instead I
store previous events in data store and insert all previous events also in session when I
get a new event.Please help me regarding the issue.
Thanks,Neel

An Event is either not counted yet, or already counted. If repeated counting
is to be avoided during repeated insertion, store the "counted" property
with the Event and write your rules accordingly.

New subject: WAS and Guvnor integration
Hi,
Currently I am using Guvnor 5.2.0 Final and deployed on tomcat 6.
In future I have to move this on WAS 7.0.11. So let me know
compatibility of both.
Also suppose I have some rules created in the current version and in
future if I have to move on the next version of Guvnor, how we can
achieve that.
Thanks

We have not verified Guvnor 5.2 on WAS yet, but this doc should give you
some ideas on how to install Guvnor on WAS:

Regarding moving rules from one version of Guvnor to another, by far the
simplest option is to perform an export from the old and an import in the
new Guvnor.
The import-export process does however loose version history.
