Hi! I tried to run decision tree operator with data that I extract from a mysql database, but rapid throw this error:
Root[0] (Process)
+- DatabaseExampleSource[0] (DatabaseExampleSource)
+- DecisionTree[0] (DecisionTree)
P May 13, 2009 10:24:46 AM: [Fatal]
OutOfMemoryError occured in 1st application of DatabaseExampleSource (DatabaseExampleSource)
P May 13, 2009 10:24:46 AM: [Fatal] Process failed: Java heap space Root[1] (Process)
here ==> +- DatabaseExampleSource[1] (DatabaseExampleSource)
+- DecisionTree[0] (DecisionTree)
How can I fix this?If it's possible to do so?
This is my .xml file:
<?xml version="1.0" encoding="windows-1252"?>
<process version="4.2">
<operator name="Root" class="Process" expanded="yes">
<operator name="DatabaseExampleSource" class="DatabaseExampleSource">

<parameter key="username" value="xxx"/>
</operator>
<operator name="DecisionTree" class="DecisionTree">
<parameter key="keep_example_set" value="true"/>
</operator>
</operator>
</process>
