If you have the Informatica Data Replication product, you can use Fast Clone as a high-speed alternative to the Data Replication InitialSync component to load target tables the first time.
Use Fast Clone for initial synchronization of target tables, prior to starting the Data Replication load operations, or to resynchronize target tables. Fast Clone can read data directly from Oracle data files, which results in better performance.
Fast Clone and Data Replication are separate products, and they do not have any version compatibility issues.
