My WebLogic Servers use JRockit JVM R28. We need to have the WebLogic JVMs configured to automatically shutdown/kill/exit when an OutOfMemoryError occurs.
A JRockit JVM Parameter called "ExitOnOutOfMemory" will let us accomplish this. However Oracle documentation provides incorrect and conflicting information.
1.) http://docs.oracle.com/cd/E13150_01/jrockit_jvm/jrockit/jrdocs/refman/optionXX.html says to simply put "-XXexitOnOutOfMemory" into startup scripts. However, JRockit doesnt "recognize" this parameter.
2.) http://docs.oracle.com/cd/E15289_01/doc.40/e15062/optionxx.htm#BABCDAIB says to put "-XX:+ExitOnOutOfMemoryError" into startup scripts. However JRockit does not recognize this configuration either. I believe they mistakenly copied this from Hotspot documentation.
How do i implement this parameter?
-XX:+ExitOnOutOfMemoryError works as expected with JRockit R28.2.2:
$ jrockit-jdk1.6.0_29/bin/java -Xmx20m -XX:+ExitOnOutOfMemoryError OOM

Which version of JRockit are you using? Did you spell the parameter correctly?
