Oracle connections where username has $?

Question

I need help tracking something down, I'm getting several connections where in Enterprise Manager it says:

OS User Name: Example$ <-- Example is the machine name.
Terminal: Example
Machine: Domain\Example

There is NO user named Example$, where is this coming from?....

I'm using Oracle 11g.

Edit: The problem I'm tracking is with an asp.net app that keeps connections open, I'm using the "using" statement everytime I open them, so that's not it. It seems to be a problem with the connection pooling.

Answer 1

MachineName$ is the Network Service account of a machine called MachineName, as seen from some other machine.

Answer 2

I'm assuming you mean sessions? An open session is not neccesarily the same thing as an open connection.

Perhaps this isn't really a problem. The connection pooling mechanism means that although you may close/dispose your use of connections, they remain in the pool for efficiency reasons for rapid re-use so that may explain why you see some Oracle sessions still alive. This is probably a good thing and a rational DBA won't have too many complaints about that.

Answer 3

It is a user that is externally authenticated via the OS.
