Java heap space error

Hi There,

I am trying to load a set of excel data (26 mb each 8 excel sheets) into database table.

But it gives me an error regarding the java heap space.


My system configuration ( windows 7, Pentaho 5.2.0.0, 4 gb ram)

This is what i have edited in spoon.bat >>>
if "%PENTAHO_DI_JAVA_OPTIONS%"=="" set PENTAHO_DI_JAVA_OPTIONS="-Xmx512m" "-XX:MaxPermSize=1024m"

After this is tried with another system, which has got 32 gb ram ( windows 7, pentaho 5.2.0.0) and the spoon.bat looks like this

if "%PENTAHO_DI_JAVA_OPTIONS%"=="" set PENTAHO_DI_JAVA_OPTIONS="-Xmx1024m" "-XX:MaxPermSize=2048m"

But still the same issue persists.

java.lang.OutOfMemoryError:Java heap space


Please help me out.

Regards
Chinmaya
