I'm puzzled. I've never seen a deadlock show up in V$SESSION or V$SESSION_WAIT before. Any deadlock I've actually seen - I've set up myself for testing purposes - usually has one statement killed by Oracle and an ORA-60 reported within a second and well before I get a chance to check these views.

I know a second is a long time CPU wise, but I'm not all that sure that a deadlock will show up in either of these views. I'm interested though in knowing whether it does or doesn't - in case anyone has seen them show up.

I've got a blog entry on deadlocks at
http://qdosmsq.dunbar-it.co.uk/blog/?p=192 and I'd like to keep it up to date.

Cheers,
Norman.
