Purpose

Sessions connecting to an Oracle database have a number of identifiers assigned to them which can be found in the V$SESSION dynamic view.

One of these identifiers is V$SESSION.AUDSID. 

This identifier is particularly useful because it can also be obtained by a session using the SQL function USERENV('SESSIONID'). 
In this way, a session can find its own session-related information.

This Bulletin explains how the value of the identifier V$SESSION.AUDSID is determined for a session. 

Scope

This document may be useful to Database Administrators and Application Developers.
