With all this, I think it's easy to kill a long query on the server (with a
small application that the administrator can run on the server):
- Just find out the user IP address and force 'close connection' on the
server. Is this ok to do? The user will get some message from the
application (if the application could detect net faults), but the
administrator will have the problem of a long query running resolved.
I have adapted Vadim Crits utility IbConsvc to do this (I must write him a
email first - I don't know if he will allow me to change this code), and put
it available to the community. I find it very useful to kill connections
when we don't want any user around....
