RE: How to find USER who locked my row ...

From: Ferris, Shawn <Shawn.Ferris_at_twtelecom.com>

Message-ID: <F001.002A9650.20010202114618@fatcity.com>

You'll need to run catblock.sql, located in $ORACLE_HOME/rdbms/admin. This will give you the views that you'll want. utllockt.sql will give a "tree view" of waiters and their blockers too. (catblock.sql required for utllockt.sql)
