We have been doing application load testing lately and I found enq TX
index contention being the top contender among other waits. The table
with 5 indexes, all it's index columns gets updated via an update for
every id in that table by no. of concurrent users defined by the load
testing scripts. 10046 trace had lot's of similar lines with varrying
p2 and p3 values.

WAIT #1: nam='enq: TX - index contention' ela= 3001942 p1=1415053316
p2=65547 p3=816

How can i overcome this wait without amending application behavior.

Is this caused by index splits ? 

Thanks
Stalin
