I need to see how my application react if I limit it to use a specific amount of memory and CPU. I am wondering how can I limit the resources for my application that is running on Tomcat and Eclipse?

I know I can use following parameters but not sure how to limit, Perm, Heap and overall Memory, and specifically CPU

-Xms1024m
    Set the minimum available memory for the JVM to 1024 Megabyte

-Xmx1800m
    Set the maximum available memory for the JVM to 1800 Megabyte. The Java application cannot use more heap memory then defined via this parameter.

    Please have a look at this thread . You can add the memory related arguments in the VM arguments section which can be seen in a picture in the below thread . http://stackoverflow.com/questions/12222153/eclipse-how-we-take-arguments-for-main-when-run – Kalyan Chavali Jun 29 '15 at 08:10
