When I am working with OBIEE 11g reports development, I have faced some issues with Graphing engine complaining or will load very slowly because of too many requests. As you all know the OBIEE 11G has updated graph engine(ADF DVT),It’s a java based component. So at this point we need increase JVM for charts and also if we are facing limited output in BI Publisher reports through Layout editor.
For this follow the below steps to address JVM issues.
1.Navigate to the config.xml file, located under the following path:
2.To increase JVM for XMLP modify the following entry from the default value, 8192 to some more value
3. To increase JVM for Charts modify the following entry from the default value, 8192 to some more value
4. Click on Save and restart Oracle BI Presentation Server service.
Have a happy report development!!!!!
