How to set the Java Plugin Heap Size in response to an OutofMemory error and in general for best performance. JAVA performance tuning for maximum performance (Doc ID 738503.1)

Last updated on DECEMBER 03, 2019

Applies to:

Oracle Demantra Demand Management - Version 7.1.0 and later
Information in this document applies to any platform.

Symptoms

Client receives error:

java.lang.OutOfMemoryError

in their java plugin log. 

There are two ways to get this log: 

1)  In the bottom, right hand part of the machine you will see a Java coffee cup icon.  Right click on it > Open Console.  Note that if there are more than one icon then look for the log that references Demantra in the URL

 

To make sure you are not including old messages, press the Clear button and then try to recreate the issue again.

 

2)  If the machine has frozen up then a log is still usually saved on the back end of the machine.  This can usually be found by going to C:/Documents and Settings/<Username>/Application Data/Sun/Java/Deployment/log

Note that this can happen in different scenarios such as, but not limited to, running a Demantra worksheet or exporting the contents to Excel
