Hi,
Recently, there was a deadlock in my Oracle database
(8.1.7.4 on Ms Windows NT 4.0) but I can't figure out
what caused the deadlock. The deadlock occurs for nearly
12 hrs and miraculously disappear. Since then the database
has been running fine without problem for the past 48 hrs.
I have attached part of the trace file. Any help is appericated.
- SESSION ID:(41.12030) 2006-05-21 21:33:07.770
DEADLOCK DETECTED
Current SQL statement for this session:
UPDATE AGENTBALANCE SET BALANCE=BALANCE - :b1 WHERE UPPER(AGENTID) =
UPPER(:b2) AND CURRENCYID = :b3
----- PL/SQL Call Stack -----
object line object
handle number name
13000a1c 179 procedure GVUSER.UP_CALLREC3
117101d4 1 anonymous block
The following deadlock is not an ORACLE error. It is a
deadlock due to user error in the design of an application
or from issuing incorrect ad-hoc SQL. The following
information may aid in determining the deadlock:
