Query causing intermittent "enq: TX - row lock contention"

edited Jul 6, 2012 1:11AM in Database Tuning (MOSC) 9 commentsAnswered
Hi,
The provided query below causes intermittent row lock contention which causes our application to hang. It is also identified by Enterprise Manager as needed to be tuned. Can someone give me an advice on what to do or where to start so that we can 'fix/tune' this query to eliminate possible application hangs.

Thanks!

UPDATE LE_HST_PS_DPT SET MO_ZR_TRN_SLS_TOT=MO_ZR_TRN_SLS_TOT+ :1,MO_ZR_TRN_RTN_TOT=MO_ZR_TRN_RTN_TOT+ :2,MO_ZR_TRN_SLS_VD=MO_ZR_TRN_SLS_VD+ :3,MO_ZR_TRN_RTN_VD=MO_ZR_TRN_RTN_VD

Howdy, Stranger!
