Disconnect vs Kill

[gtcol]

Then I decided to use 'disconnect'. This seemed to be really effective ... removing the session from v$session AND also removeing all the O/S process.

So I guess my reason question is ... why use 'kill' at all?

I don't believe it always works, meaning 'disconnect' doesn't always remove the session from v$session. 'disconnect' just closes the connection the session is using; the v$session entry will not go away unless the rollback is complete or the session is killed on OS level.
