For bidirectional streams setup, Please run steps 1 through 8 after interchanging Db1 and Db2. Caution should be exercised while setting the instantiation SCN this time as one maynot want to export and import the data. Export option ROWS=N can be used for the instantiation of objects from DB2--> DB1.
