Please Help: table locking

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. Session 13 is held as EXCLUSIVE and Session 29 are requesting as SHARE. What does that mean and would this be a hint to solve this problem?

I do not specify any locking feature explicitly in my application at all.

Please Help!! Thanks.

Susan
