You can configure the SAP BW system to use load balancing. To support an SAP BW system configured for load balancing, the SAP BW Service records the host name and system number of the SAP BW server requesting data from PowerCenter. The SAP BW Service passes this information to the PowerCenter Integration Service. The PowerCenter Integration Service uses this information to load data to the same SAP BW server that made the request. For more information about configuring the SAP BW system to use load balancing, see the SAP documentation.
You can also configure the SAP BW Service in PowerCenter to use load balancing. When you create the SAP BW Service, define an SAP load balancing connection. If the load on the SAP BW Service becomes too high, you can create multiple instances of the SAP BW Service to balance the load. To run multiple SAP BW Services configured for load balancing, create each service with a unique name but use the same values for all other parameters. The services can run on the same node or on different nodes. The SAP BW server distributes data to the multiple SAP BW Services in a round-robin fashion.
