I have an app that open 2 database connections concurrently. It hangs couple times a week due to table lock. The following is a report shows what happen:

USERNAME SID SERIAL# TY HELD REQUEST

---

SQL

PROD_USER 13 124 TX Exclusive None UPDATE object set flag = 1 WHERE plan = 'A' AND Id = 3466629

PROD_USER 29 9034 TX None Share UPDATE object set flag = 1 WHERE plan = 'B' AND Id = 3466631;

The two sessions(SID 13,29) are updating different rows so I have no idea how this can generate locks. I do not set up any locking feature. I tried to disable all foreign keys but it didn't help. I also tried rebuild the corresponding tables and indexes(I suspect due to corrupted indexes) but still didn't help.

Please help!

Susan
