I have a java process which has two threads executing two different programs running on solaris. When I kill the process I get core dump how can I avoid this and stop the process through a shell script.

I think you need to use a shutdown hook in the vm to tell your running threads to stop. A shutdown hook is just a means to enable graceful exit.

You add the shutdown hook thus:

where shutdownHook is a thread.

The VM only exits when all the shutdown hooks have been run. But, depending on how the VM was terminated, the shutdown hooks may not have a chance to run at all. I think using something like 'kill -9 pid' will kill a VM without hooks running, but CTRL-c for example will allow the hooks to run.
