Collisions in the Replication Server Log File
Because of the overhead involved, the Replicator Server by default does not look for collisions or attempt to resolve them. You can control collision detection and resolution through CDDS collision modes. If a collision does occur, the Replicator Server identifies the condition as an error. For example, the server issues errors such as:
The target record cannot be found in the target database or
or
A primary key was already in the target database for an insert transaction.
If you find these types of errors in the replicat.log file, this indicates a collision condition.
