What is Simulation in ODI?

Simulation option will be available at Mappings(12c) or Interfaces in 10g or 11g.

If we select this option while execution time it will give us complete report or background process
for your mapping or interface.  In Below example I have enable CDC on Source table.

Source Table:  HR. EMP1  ( JKM Simple CDC enabled this table)
Target Table:  DEV. EMP1
Knowledge Moduels:

--------------------------
LKM:   LKM SQL to SQL
IKM:  IKM SQL Incremental Update
Options:  FLOW_CONTROL=false ( CKM is not required)
bcz i am not validating Constraint data in this example.
