Re: [rules-users] Analysing OutOfMemory, too many RightTuple
Most of the RightTuple's sinks are AccumulatorNodes. Here is one of the 80
rules that I believe cause my problem. The other 80 rules are similar, but
will change in the places I formatted in /italic/.
Some information on this rule:
* The EvemetierData is the business class. They are 10-100k instances in the
VM.
* It has a accompaning object EvemetierCalculDHF that store some temporary
rules data. In particular, the calculationMode to use for a given
field=attribute
* The AttributEvemetierDHF is a Meta information class with a dozen
instances (one per field to calculate in EvemetierData) in WM.
* The UNWRAP_NULL it there to enable Null values to passe the accumulator
(an Option would have been clearer)
rule "valo_2a_applyCalcMode_evemetiers_som_nivinf_1"
salience -1110
when
$attDHF:AttributEvemetierDHF()
$evCalcDHF:EvemetierCalculDHF(calcModes.get($attDHF.calculationModeKey)=="/som_nivinf_1/")
$obj:EvemetierData() from $evCalcDHF.evemetier
accumulate (
$src: EvemetierData (
/pere==$obj.niveau,
affperiode==$obj.affperiode,
typeeve_id==$obj.typeeve_id,
dteve==$obj.dteve,
suffixe==$obj.suffixe,/
true);
$acc1 :
sumWithNulls(/DIVIDE($src.getAttributeValue($attDHF.safeGetAttName("valo_2a_applyCalcMode_evemetiers_som_nivinf_1")),
$src.getAttributeValue($attDHF.safeGetCoefinterniv("valo_2a_applyCalcMode_evemetiers_som_nivinf_1")))/
)
);
$targetValue:Object(EQUALS(UNWRAP_NULL(this),$obj.getAttributeValue($attDHF.attName))==false)
from WRAP_NULL($acc1)
then
$obj.setAttributeValue($attDHF.getAttName(), UNWRAP_NULL($targetValue));
end
