When the "hang" occurs, run the following query:

SELECT DECODE(request,0,'Holder: ','Waiter: ')||sid sess, id1, id2, lmode, request, type
FROM V$LOCK
WHERE (id1, id2, type) IN
(SELECT id1, id2, type FROM V$LOCK WHERE request>0) ORDER BY id1, request
/

It very well could be that the application is pausing on ENQUEUE waits. Received on Fri Dec 30 2005 - 17:07:57 CST
