When creating the plugin-cfg.xml file, the WebSphere Application Server Proxy Server is unable to generate the LoadBalanceWeight field from the administrative console

Troubleshooting

Problem

The administrative console for WebSphere Application Server V7.0 does not display any "Weight" field corresponding to any proxy server cluster member. While creating a proxy server cluster member using the administrative console, you do not get an opportunity to specify the "Weight" attribute of proxy server cluster members.

Symptom

The weights of proxy cluster members gets reflected in the plugin-cfg.xml file, the static routing file generated for the plug-in component for routing HTTP requests from a Web server to proxy server cluster members.

If a proxy server cluster is created using the administrative console, all the cluster members will be associated with a default weight of 2. A generated plugin-cfg.xml file will show a section somewhat like the following:

`<ServerCluster Name="ODRCluster" CloneSeparatorChange="false" LoadBalance="Round Robin" PostSizeLimit="-1" RemoveSpecialHeaders="true" RetryInterval="60">` `<Server Name="ProxyCluster-Member1" ConnectTimeout="0" ExtendedHandshake="false" MaxConnections="-1" WaitForContinue="false"` `LoadBalanceWeight="2">` `…` `</Server>` `<Server Name="ProxyCluster-Member2" ConnectTimeout="0" ExtendedHandshake="false" MaxConnections="-1" WaitForContinue="false"` `LoadBalanceWeight="2">` `…` `</Server>` `</ServerCluster>` `…`

Along with other attributes, each proxy server cluster member will have a LoadBalanceWeight attribute. Note the default value of 2 of the LoadBalanceWeight attributes associated with both the cluster members in the preceding sample snippet.

This might become a problem in an asymmetric environment where proxy cluster members might be created on dissimilar machines.
