Hi,
I am new to clover etl and I am modifying some applications that use clover ETL.
When I running my application it throws the following exception:
Exception in thread "LOOKUP1" java.lang.OutOfMemoryError: Java heap space
Exception in thread "WatchDog" java.lang.OutOfMemoryError: Java heap space
The Error ocurrs in this node
<Node id="LOOKUP1" type="RERANGELOOKUP" leftOuterJoin="true" OutFlag="TYPE" StartRangeKey="StartRange" EndRangeKey="EndRange" LookupKey="cNumber" ></Node>
The file where Clover makes the LOOKUP is quite big: 6915782 lines.
I wonder if I use the commercial engine of Clover ETL will fix this problem or if it is a hardware problem.
How could I solve this issue? Please help.

Hello,
your custom node probably stores all data in the memory, so you need to set more memory for the jvm (see Fine-tuning CloverETL). If you have CloverDesigner, the above settings can be configured in CloverETL launch configuration (see Running Graphs).
