harm in kill-ing tomcat?

[Nick Wesselman <ni...@digivis.com>]

The shutdown script takes so long... is there any harm in "kill -9"-ing 
tomcat? What about when a connector like mod_jk is in use?

I suppose if there is anything transactional going on in my code, that 
could be bad. I'm guessing the shutdown script waits for all current 
processing to finish?

What about DataBase connections and possible sessions that will be cut in half?

Well, when you turn off your computer, do you shut it down or hit the switch? 
"kill -9" is like using the "Frankenstein switch" instead of a shutdown.

DBs should survive the death of connection, sessions, even on application level 
should have timeouts and clean-up procedures, so the system SHOULD SURVIVE shot 
in the head. The same can be said for pulling the plug on your computer instead 
of a clean shutdown - it should survive. And it will, for a number of times. 
Until one day,....

Nixie.
