Replication Guide and Reference

Defining an External CCD Table as a Replication Sources

Changes captured within applications or other system tools, such as DataPropagator NonRelational, can also be defined as sources for replication subscription. The external data source must provide a complete CCD table, which you can define as a replication source with the Control Center and use as a surrogate source table. You can create the CCD table outside of the replication tools, have your application populate it, and then define the table as a replication source. See "External Data Sources" for more information about external data sources.

To define a CCD table as an external replication source:

1. Create and populate the CCD table with the user data columns in CCD table format, to hold changes that originated from the external data source. See Chapter 20. "Table Structures" for more information about CCD table format.

2. Define the CCD table as a replication source. See "Defining Replication Sources".
