Subject Re: database became broken for any reasons

So if I kill all connections(clear table MON$ATTACHMENT) and then I'll try to kill processes all will be ok(or myabe I don't need it)?

I'll try to do such example:
1) I connect from remote computer to test server using SYSDBA, not my user
2) I start big select (it's take about 2-3 minutes, really big table)
3) On test server send database to shutdown - It's work, database in shutdown mode, and then return online

What's wrong?

I't seems to me that this connections kept by sleeping applications in terminal. I never see this bug on server without terminal(I may mistake, but it seems to me I right)
