  Your rules are probably written wrong, or your application, or you have a
 dodgy computer, or you have a race condition, or it is doing exactly what it
 should be doing and your expectations are wrong.

 There’s also possibly a small chance that there is a bug in drools but with
 absolutely no information about what the problem is or what you are doing
 I’d be inclined to check all the other options first.

Re: [rules-users] Problem in update() method

@ Esteban

i use update to  update my object  so that when my next rule is called
it should receive the updated value  from the previous rule.

so  using
*lock-on-active*
will allow me doint that or not ??

 If both rules are in the same agenda group you can use lock-on-active

 Best,

 2010/5/13 Greg Barton greg_bar...@yahoo.com

   It is so because that's what you're telling the system to do. :)

 The no-loop modifier only prevents a rule's conditions from infinitely
 re-evaluating the tuples modified by it's own action, not the actions of
 other rules.  So when rule Area_EstimatedRval_test_10-01-09_12-31-14
 modifies a Para_2483 it will be reconsidered by the conditions in
 Area_EstimatesRval4_10-01-09_12-31-14.  The only way to prevent
 Area_EstimatesRval4_10-01-09_12-31-14 from firing again is to craft it's
 conditions such that they're no longer true. (maybe fid2329 != eid2143
 since that contradicts what Area_EstimatedRval_test_10-01-09_12-31-14
 does, but I don't know if that makes sense for your rules.)

Re: [rules-users] Insert Fact Speed bottleneck

2010-05-05 Thread Puneet duggal

@ djb ,

Can u tell  me how did u inserted the facts urself ??
Is a  just a simple  assertion or  any  thing else ?



On 5/5/10, djb dbrownel...@hotmail.com wrote:


 Hi Drools team,

 I wrote a Drools application for my company, which evaluates clinical claim
 processing rules.  That is, it checks current medical claims against the
 patient's historical claims.

 It appears that 95% of the run time is dedicated to inserting facts, which
 is presumably when it propagates through the RETE graph, since firing the
 rules takes no time.

 But it seems like it's not fast enough.  I made a rule template, which by
 trial and error of moving the conditions around, is optimised.  I'm
 averaging 310ms, and need it to be under 170ms for it to be viable.

 Is there any not-too-technical guide to optimisation somewhere?  (alpha and
 beta-nodes scare me a bit).

 Regards,
 Daniel

 I suggest that you do not use mvel unless there is a compelling reason

 Here, I've found this for you, a comment from the Drools source file
 org.drools.rule.builder.dialect.java.JavaDialectConfiguration

 * There are options to use various flavours of runtime compilers.
 * Apache JCI is used as the interface to all the runtime compilers.
 *
 * You can also use the system property drools.compiler to set the
 desired compiler.
 * The valid values are ECLIPSE and JANINO only.
 *
 * drools.dialect.java.compiler = ECLIPSE|JANINO
 * drools.dialect.java.lngLevel = 1.5|1.6
 *
 * The default compiler is Eclipse and the default lngLevel is 1.5.
 * The lngLevel will attempt to autodiscover your system using the

 *
 * The JavaDialectConfiguration will attempt to validate that the
 specified compiler

 Try it without the JANINO setting - it *should* flag the setter with
 the incompatible types.

 If you haven't used MVEL so far, I don't see any reason to start now.
