Column Mapping

There are two methods for mapping key columns and comparison columns:

System-generated: Column mappings are configured automatically by Oracle GoldenGate Veridata at runtime based on current object metadata.
User-defined: Column mappings are configured manually by an Oracle GoldenGate Veridata user who has the Administrator or Power User role.

All new compare pairs default to System Generated for key columns and for comparison columns. You can change to a different mapping method at any time. More
