Using the Prebuilt Update Conflict Handler
The Oracle-provided prebuilt update conflict handler uses one of four predefined methods to resolve the conflict. These methods are OVERWRITE, DISCARD, MAXIMUM, and MINIMUM.
The conflict handler is defined for the destination table using the SET_UPDATE_ HANDLER procedure in the DBMS_APPLY_ADM package. The parameters for the procedure are listed in Table 10-1. The same procedure is used to modify or remove an existing conflict handler.
