Add JVM parameters as below in setupDatabase.xml.
<condition property="jvm.args" value="${jvm.arg.mem.max}" else="-Xms2048m -Xmx6144m -XX:PermSize=2048m -XX:MaxPermSize=4096m -Djava.awt.headless=true">
<!-- Support old scripts which may still use this property -->
<isset property="jvm.arg.mem.max"/>
</condition>
