Recently while running Tomcat under Eclipse for one of the web application I was getting Java Heap memory related error java.lang.OutOfMemoryError.
What needs to be done here basically is to increase the jvm heap size. So for increasing the JVM Heap Size of Tomcat in Eclipse we have to set few VM arguments of the tomcat. Follow the simple steps to change the Heap Size of Tomcat under Eclipse.
1. Open the Server tab in Eclipse and double click the Tomcat server to open Server Configuration. 2. In Server Configuration, click on the Launch Configuration link under General Information. 3. Under Arguments tab, add following values in VM arguments.
Hi, Thx for the tip ;) Is there a way to persist this change in an external config file (or other) to avoid edit launch configuration each time eclipse is restarted ? Thx in advance.
Hi, Could any one explain the advantage of initializing the instance variables inside a constructor, the same thing we can do after the object has been initialized and calling the respective setters method.
Max Limitations of heap space is depends on your Server capacity & Ram. For 1Gb there wont be problem . if you have 8 gb ram there wont be problem to keep you Heap size limited to 2 Gb
Setting vmargs in Eclipse.ini to the below and then making the above change in tomcat worked for me.:) -vmargs -Xms256m -Xmx1024m -XX:PermSize=64m -Xss1M -server -XX:+DoEscapeAnalysis

-vmargs
-Xms256m
-Xmx1024m

But Still my problem is not solved. It is saying that,”java.lang.OutOfMemoryError: PermGen space”
