Re: [rules-users] java.lang.OutOfMemoryError: Java heap space

Hi laune, I'll explain the process briefly. I’m getting voice call events from our billing system. We want give some offers if call made inside specific cell (uploaded this fact to WM in advance) . But we have to give offer only once per day. So repeated calls inside this cell won’t eligible for offer again. To achieve this we initiate a new event(NotificationEvent) and insert into WM and set metadata @expires(24h) against each mobile no. Ultimately over 1000K NotificationEvents are residing in WM per day and guess it will trigger OutOfMemory exception. How to handle such a case? Do we need to use caching mechanism? Thanks. see below code snippet rule "Voice CYM offer selector" dialect "java" no-loop true when $vc : VoiceCallEvent( $ct : eventTime, $cell : cellID, $mobile : originNumber) from entry-point "IN-VOICE-CALL-EVENT" $offer : CymOfferInfo($valTo : validTo.time >= $ct, cellId == $cell,$offerId : offerType.getId, $msgContent : cepMsgTemplates.getId) not( OfferedEvent(mobileNo == $mobile , offerId == $offerId )) then CYMOfferMessage genMsg = new CYMOfferMessage(); OfferedEvent offered = new OfferedEvent(); offered.setMobileNo($mobile); offered.setOfferId((String)$offerId); genMsg.setMobile($mobile); genMsg.setMsgContent($msgContent); /* atttach offer here */ /* drop SMS message to queue & block offer trigger again*/ mdbService.dropMessage(genMsg); insert(offered); end -- View this message in context: http://drools.46999.n3.nabble.com/java-lang-OutOfMemoryError-Java-heap-sp...
