STL_SESSIONS
Returns information about user session history.
STL_SESSIONS differs from STV_SESSIONS in that STL_SESSIONS contains session history, where STV_SESSIONS contains the current active sessions.
STL_SESSIONS is visible to all users. Superusers can see all rows; regular users can see only their own data. For more information, see Visibility of data in system tables and views.
Some or all of the data in this table can also be found in the SYS monitoring view SYS_SESSION_HISTORY. The data in the SYS monitoring view is formatted to be easier to use and understand. We recommend that you use the SYS monitoring view for your queries.
