convert_not_nullable_column
Use this system parameter to control how CDC Replication behaves when it applies a null value to a non-nullable column.
When set to true, the null value will be replaced with a default value (based on the data type of the column) and CDC Replication will generate a warning in the event log. When set to false, CDC Replication applies the null value directly to the non-nullable column which will result in an error and cause a shutdown of CDC Replication on the target database.
Note: If you decided to set this system
parameter to false and have specified this as an error for CDC Replication to
ignore using the mirror_expected_errors_list system
parameter, then CDC Replication will
ignore the error and not shutdown.
