Home -> Community -> Mailing Lists -> Oracle-L -> RE: table lock problem?
How about trying v$session_wait and v$session_event? That should tell you what it is waiting for.

Hi all,
I had a developer come to me yesterday and tell me his session had hung, and sure enough it had, he was executing an INSERT into a table with 5 columns. Oracle was just sitting there, but all the other sessions logged into the database were fine. I got the SQL out of the SQL Area and ran it in one of my own SQL*Plus windows, and sure enough it got stuck for me too. The statement was part of a transaction that inserted and updated about 8 tables, and this happens on the 3000th or so transaction in that session. We killed that session and restarted the application, and it was fine until it happened again.
How would I go about diagnosing something like this? A couple of the columns were from sequences, and I verified that these were OK. The others were just text inserted into VARCHAR2s.
Thanks,
g
