    Autonomous Databases

    OGG 18c supports only Delivery (Replicat) for below,

    • Autonomous Data Warehouse Cloud

    • Autonomous Transaction Processing

    To replicat to ADWC, you need to use Non-Integrated Replicat processes. It means, you need to use either of the below,

    • Classic Replicat

    • Coordinated Replicat

    • Non-Integrated Parallel Replicat

    Identity Columns

    OGG 18c supports ID columns (Identity Columns) with some conditions,

    • The Database should be Oracle 18c (18.1.0 or 18.3.0).

    • Only DML can be replicated and DDL is not supported.

    • You need to have either Integrated Extract and Integrated Replicat or Integrated Parallel Replicat to use this feature.

    • Classic Extract or Classic Replicat will not support this feature.

    Auto CDR

    From OGG 18c, you can configure Auto CDR the tables with Unique Key (UK) also. But this can be done only when your database is Oracle 18c.


    Composite is sharding is supported by OGG 18c when your database version is Oracle 18c. It allows for sharding using HASH partitions also.

    In Database Row Archival

    OGG 18c enables replication of compressed and invisible rows. But this feature is also supported only when you use Oracle 18c database.

    There are also lot many of features. Currently started testing one by one. Will see all these in detail in my upcoming posts.

    Cheers 🙂
