Load Balancing Failure When Using an External Load Balancer

(Doc ID 957051.1)

Last updated on NOVEMBER 05, 2016

Applies to:

Oracle Weblogic Server - Version: 8.1 to 10.3.2
Information in this document applies to any platform.

Symptoms

You have a WebLogic Server (WLS) environment with a cluster with four nodes and an external load balancer using the Apache plug-in. The load balancing is not working as expected. In the first access, all four nodes receive requisitions, but after the first access, only one node receives subsequent requisitions. You expect that the load should be balanced in Round-Robin fashion across all the nodes in the cluster.
