Hi,

On Linux, you start by using vmstat to see if there is any disk swapping at the system level:

For weblogic swapping, read this, all about it:

BTW, Martins weblogic books are amazing:

http://rampant-books.com/book_0214_weblogic_automation.htm


http://www.rampant-books.com/book_0516_web...ultitenancy.htm

If you have real disk swapping, processes will come and go too quickly to identify any particular process.

The real issue is the proper allocation of RAM and swap! Please read carefully:

Hope this helps . . .
