Tracking Closed Oracle Database Sessions
The dynamic view v$session has the OSUSER details through which we can track which user logged in and ran a particular query but i guess through this we can only track active and inactive sessions( only the sessions which are open). The OSUSER tells us which user logged in and performed Database activity even though the database schema user, e.g. "RMS13" may be common for all the users.
How do we track the closed sessions?Is there any way or any view which gives information on these sessions. Something like the OSUSER column which can make it possible to track the particular user who made changes in the database. I have heard of traces but they impact database performance negatively.
