Folks Sorry for blank mail earlier. Hit send by accident. Need your suggestion to migrate data from oracle to oracle db instance for OLTP application. 1) This migration need 50% table data transformation from source db to target db 2) Need to do migration with index/constraints/triggers enabled on Target OLTP instance during other users using this instance at production mode. Recommended GoldenGate and Streams at my place. There is a lack of knowledge and no one want take risk. Written db package solution uses dblink for data migration using metadata. I have been told running SQL Plus using dblink is much faster then DB package. Waiting for benchmark. Anyone migrated data to live OLTP instance with index/triggers/constraints enabled in Oracle tools Appreciate your help Thanks Karth On Sep 5, 2013, at 6:29 AM, Karth Panchan <keyantech@xxxxxxxxx> wrote: > > -- //www.freelists.org/webpage/oracle-l
