IBM WebSphere - Setting web server plugin (plugin-cfg.xml) Round Robin

Updated:   |  IBM WebSphere articles

This assumes you have already done the following:

 


Round Robin

Let's say you have an application that is configured to use your IHS web server (was.software.eng.us in this example) and two (or more) application servers in a static cluster or dynamic cluster (cluster01 in this example).

 

As requests come into the IHS web server, Round Robin would ensure that requests are evenly distributed to the application servers in the cluster.

 

In the WebSphere admin console, navigate to Servers > Server types > Web servers > your web server > Plug-in properties > Request routing. By default, Round Robin will be selected.

 

Likewise, the ${WAS_INSTALL_ROOT}/profiles/your_profile/config/cells/your_cell/nodes/your_node/servers/your_server/plugin-cfg.xml file will have the same configurations as shown in the dmgr.

<ServerCluster 
  CloneSeparatorChange="false"
  GetDWLMTable="true"
  IgnoreAffinityRequests="false"
  LoadBalance="Round Robin" 
  Name="Cluster1"
  PostBufferSize="0"
  PostSizeLimit="-1"
  RemoveSpecialHeaders="true" 
  RetryInterval="60"
  ServerIOTimeoutRetry="-1">

 


multiple plugin-cfg.xml files

Be aware that there is a global plugin-cfg.xml file on the dmgr, located at:

${WAS_INSTALL_ROOT}/profiles/your_profile/config/cells/plugin-cfg.xml

 

However, the Request Routing page in the WebSphere admin console would update the server specific plugin-cfg.xml, located at:

${WAS_INSTALL_ROOT}/profiles/your_profile/config/cells/your_cell/nodes/your_node/servers/your_server/plugin-cfg.xml
