Lock or pin java process into memory.
 

Hi,

Is there a way to lock a java process into memory.

Using something like mlock/mlockall it is possible to lock the memory of a process into memory, so that it doesn't get swapped out. With this approach is it possible to write a C wrapper before invoking the java process to lock the java process into memory? If so, how would the wrapper invoke the java program - fork/clone/vfork/execl?

Or maybe there is some other way to lock a java process into memory?

Thanks, Parik

There are tutorials on the internet that will tell you how to start a JVM and such from C, but an easier solution might be to use the Java Native Interface (just Google it and you'll find loads of info) so you can call a function that calls mlock()/mlockall() from Java.
