I'm setting up a Oracle Internet Directory / Enterprise User Security implementation here. When user Enterprise User ABC connects to the database via Sqlplus abc/password they are actually connected to database account xyz. Select user from dual; USER --------- XYZ What I want to be able to see is the 'abc' enterprise username for a particular session. I know I can see it for my own session using select sys_context('USERENV','AUTHENTICATED_IDENTITY') from dual; SYS_CONTEXT('USERENV','AUTHENTICATED_IDENTITY') ------------------------------------------------------------------------ -------- ABC But if I'm trying to track down which user is running a particularly nasty query in my beloved production database, how do I determine it for that session? -- //www.freelists.org/webpage/oracle-l
