sqlplus how to find details of the currently connected database session

oracle, sqlplus

Solution

Take a look at this one `(c) Tanel Poder`. You may either run it from your glogin.sql (so these settings will update each time you connect, or just run it manually. Notice `host title` command - it changes your sql*plus console window title with session information - extremely useful with many windows open simultaneously.
