It may occur only in production after running for a long time. The purpose of this article is to explain the use of Heap analyser tool to identify the memory leakage of larger enterprise java applications, which uses larger size of heaps.

How to take thread dump of a running application in Oracle and IBM Java ?

A thread dump will help a developer to identify the application hanging issues and performance issues. To analyze this, please take, a continuous snapshot of thread dumps and analyze using a thread dump analyzing tool. In Oracle Java you can use jstack tool. This executable is available in the JAVA_HOME/bin folder. Use the following command ' jstack -l <PID> >> threaddump ' . This will write the thread dump into a file 'threaddump' in the directory from you have executed the command. <PID> should replaced with actual process id. You can use the following command to find the process id in Unix. ' ps -ef | grep java ' . In IBM Java you can use ' kill -3 <PID> ' . This will write the thread dump in application running console or in nohup file or a thread dump file will be generated in the program running directory.
