Tom, would a monitor in place have notified the admins as to a locking
issue? I usually run Steve Adam's enqueue.sql script to find locked
objects. Also have monitors in place that generate an email when locked
exceed a specific time. Pretty typical for me to call an app dev and ask
him if he forgot to issue a commit, which is usually the case. By the way
I second the book recommend. I went to once of Gaja's presentations and
got the gist of the methodology but when I bought the book I was able to
actually absorb it.

Subject: Oracle 101 Performance Tuning comes to the rescue again!All,you *MUST* buy this book.I just got called over by the Warehouse people. Their database was hung. We could log-on ok, but certain queries would hang.Ran the four "wait-state" queries and saw that two queries were hung on library cache. the two queries were an analyze table and a MV refresh - using the same table. hung them both out to dry.killed the analyze and the MV started up again.great book. solves all problems. great job Gaja, Kirti and John. you guys do the work, and I look like a hero.thanks again.Tom Mercadante
