Tomcat is run in its own JVM instance, so you'll need that separately. Assuming you use WTP to start your Tomcat instance, you need to go to your Server configuration, click "Open launch configuration" and there (on the "Arguments" tab) edit/add the VM arguments to include the desired -XX:MaxPermSize argument. share|improve this answer answered Oct 24 '11 at 15:52 Joachim Sauer 184k35394501 3 adding the argument to the end of the variables, right: -Dcatalina.base="C:\Workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0" -Dcatalina.home="D:\apache-tomcat-7.0.22" -Dwtp.deploy="C:\Workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps" -Djava.endorsed.dirs="D:\apache-tomcat-7.0.22\endorsed" -XX:MaxPermSize=512m –fresh_dev Oct 24 '11 at 15:57 add a comment| up vote 15 down vote No. Tomcat runs in a separate JVM from eclipse.

How To Resolve Java.lang.outofmemoryerror Permgen Space
a Java program runs into a OutOfMemoryError: PermGen Space error. I first explain what the permanent generation heap space is, after permgen space java 8 which I explain the usual cause of the Permgen Space error and I give some pointers on how to avoid it. Introduction Usually, we do not look into JVM intrinsics. We take the JVM as http://stackoverflow.com/questions/7878306/avoid-permgen-space-error-when-running-tomcat-from-eclipse is. Some of the world’s finest engineers are working on the JVM(s) and I am sure we can’t improve their work, definitely not without getting seriously involved. However, as a Java developer, you are often confronted with performance issues, usually working memory related. The problem I run into most is the dreaded OutOfMemoryError: PermGen Space error. I thought it would be nice to know more about it, so I looked http://www.integratingstuff.com/2011/07/24/understanding-and-avoiding-the-java-permgen-space-error/ into what causes it exactly. Java memory structure To understand the error, we have to look into how the jvm memory is structured. There are two memory regions in the JVM: the heap and the stack. Local variables and methods reside on the stack, everything else on the heap. This Java heap memory is structured again into regions, called generations. The longer an object lives, the higher the chance it will be promoted to an older generation. Young generations(such as Eden on Sun JVM) are more garbage collected than older generations(survivor and tenured on Sun JVM). However, there is also some separate heap space called permanent generation. Since it is a separate region, it is not considered part of the Java Heap space. Objects in this space are relatively permanent. Class definitions are stored here, as are static instances. Without getting into details, Classloaders deploy and undeploy classes all the time. For example, this happens when an application is deployed or undeployed on a webserver. On web servers, all applications have their own Classloader. When an application is deployed or undeployed, its class definitions and Classloader are respectively put into and removed from the permanent generation heap. OutOfMemoryError: PermGen Space The OutOfMemoryError: PermGen Space error occurs when the permane
"java.lang.OutOfMemoryError: PermGen space" error? How can I avoid the "java.lang.OutOfMemoryError: PermGen space" error? This error means that the non-heap memory limit of http://support.veryant.com/support/phpkb/question.php?ID=224 the JVM has been reached. The non-heap memory is used to store class descriptions, so this error may appear when running huge applications. To avoid it, you must increase the non-heap memory limit by adding -XX:MaxPermSize=256m Java option to the command line: iscrun -J-XX:MaxPermSize=256m PROGNAME or java -XX:MaxPermSize=256m PROGNAME 256 means 256 MB and it specifies the maximum amount permgen space of non-heap memory that the JVM can allocate. If it’s not enough, try with higher values. Authored by: Veryant Support This question has been viewed 3534 times so far. Click Here to View all the questions in isCOBOL General category.
