Load balancing with the NameServer
Load balancing is a feature that allows client connection requests to be distributed, based on load, among multiple Unified broker instances that support the same Application Service. If your product includes load balancing (for example, the WebSpeed Enterprise Transaction Server) or you have installed the load-balancing option for a product that requires it (for example, the AppServer), the NameServer assigns client connections to the appropriate Unified broker instances based on weight factors that you specify.
If the weight factor that you specify for each Unified broker instance is appropriate in relation to the others, the effect is to assign more connections to broker instances with greater resources, and thus to balance connection load among all the instances. You can set the load-balancing weight factor for each Unified broker instance in OpenEdge Management or OpenEdge Explorer or by editing the priorityWeight property in the file.
For more information on load balancing and fault tolerance, see Understanding the NameServer's load-balancing option, and OpenEdge Getting Started: Installation and Configuration.
Note: The NameServer can be on any machine in your network, even in Windows. In addition, you can configure your Transaction Server to run without a NameServer. For more information, see Eliminating the NameServer.
