I am using Tomcat server and I want to get a heap dump on Out of Memory error.
How can I do this by specifying parameters in the Catalina.bat file?
Also is there a way to specify the path where the dump file is stored?

    According to this http://www.oracle.com/technetwork/java/javase/tech/vmoptions-jsp-140102.html
    you can use option -XX:HeapDumpPath=./java_pid<pid>.hprof.

    You do not have to modify calatalina.bat or other scripts to add options to Tomcat. Just set system variable CATALINA_OPTS before running Tomcat.
