Hi,

I need to extract the current user logged in to the OS from my trigger. Does oracle store / have access to this information? If so, how do we get it?

Thanks!

Hmm...

You need to know the user logged in the OS from inside ORACLE ? There could be users logged into the OS but not connected to Oracle at all ? Or did you mean people connected to Oracle ?

check out v$session as follows:

select username, osuser from v$session;

Hi,

What I really need to do is build an audit trigger, which would fire is someone made an insert, update or delete on a table and the trigger would then log the user id (unix id) of the user who made the change.

Is there a way to get this info?

Thanks a ton!

select sid, serial#, osuser from v$session;

gives most of the information needed.

Hey,

Got a question again. The query works fine from SQL Plus but when I use it in my trigger (connected as system), it doesnt compile the trigger and complains of "sys.v_$session needs to be declared". Any thoughts?

Thanks

I had developed the query for a trigger (just like you) for auditing purposes quiet some time back. I do not recall any problems though. Sorry that's all I can help/share with at the moment.

Later.
