The following are the benefits of using integrated Replicat versus nonintegrated Replicat.

• Integrated Replicat enables heavy workloads to be partitioned automatically among parallel apply processes that apply multiple transactions concurrently, while preserving the integrity and atomicity of the source transaction. Both a minimum and maximum number of apply processes can be configured with the PARALLELISM and MAX_PARALLELISM parameters. Replicat automatically adds additional servers when the workload increases, and then adjusts downward again when the workload lightens.

• Integrated Replicat requires minimal work to configure. All work is configured within one Replicat parameter file, without configuring range partitions.

• High-performance apply streaming is enabled for integrated Replicat by means of a lightweight application programming interface (API) between Replicat and the inbound server.

• Barrier transactions are coordinated by integrated Replicat among multiple server apply processes.

• DDL operations are processed as direct transactions that force a barrier by waiting for server processing to complete before the DDL execution.

• Transient duplicate primary key updates are handled by integrated Replicat in a seamless manner.
