HandleCollisions parameterUse the HANDLECOLLISIONS
and NOHANDLECOLLISIONS
parameters to control whether or not Replicat tries to resolve duplicate-record and missing-record errors when applying SQL on the target. These errors, called collisions, occur during an initial load, when data from source tables is being loaded to target tables while Oracle GoldenGate is replicating transactional changes that are being made to those tables. When Oracle GoldenGate applies the replicated changes after the load is finished, HANDLECOLLISIONS
provides Replicat with error-handling logic for these collisions.
