Using the sample user exit programs
CDC Replication provides several sample user exit programs for table/row-level operations, row filtering expressions, expressions, and notifications. You can use these samples as a starting point for creating your own user exit programs by inserting your customized code.
The sample user exit programs are automatically installed with CDC Replication, and are members in the DMCSRC source file that is placed in the CDC Replication product library.
