Objects Created on the Oracle Publisher

Microsoft SQL Server replication installs database objects on the Oracle Publisher to enable change tracking and forwarding (SQL Server does not install any binary files on the Oracle Publisher). The following table lists the objects that are created at the Oracle Publisher when it is identified as a Publisher at the SQL Server Distributor. The object descriptions are provided for informational purposes only. These objects should not be modified.
