It's library cache instance lock. "O" is the namespace. Try killing processes
manually, using something like
ps -ef|grep "ora_"|awk '{ print $2; }'|xargs kill -9
On a Solaris system you can do something like "pkill -9 ora_"
and then removing SGA by iprm.
That would be the equivalent of "shutdown abort".
