I have had multiple instances where I had to kill the dispatcher process on 9i to enable people to log on again.
Sometimes, the connected sessions would still work, so I just changed tnsnames.ora to use dedicated sessions until the end of the day (at which time I could kill the dispatcher when there were no more shared sessions connected).

After you kill the dispatcher with stop/id, it is automatically restarted and people can connect again.

A few tiomes, too, I had to kill one or 2 runaway (100% CPU) shared server processes (thus disconnecting 1 or 2 clients) to free the dispatcher.

When this happened, the sessions of users wanting to connect appeared to freeze. The dispatcher is simply not responding to the request, or something.

On 10g, it happened only once on a test instance. I didn;t spend a lot of time investigating then.

I sure hope this is less of a problem on 10g. I use shared connections to save on memory with sometimes a lot of web users connected, never know how many thay can be.
