Altering the plug-in Load Balancing and Fail Over options
 Technote (troubleshooting)
 
Problem(Abstract)
Every so often a need arises that dictates that a particular cluster member should no longer be part of the Load Balancing / Fail Over listing.
 
Cause
The cause for this situation could be related to a back-end application server that is going down, or you might want to bring an application server down for maintenance. Either situation requires that requests should no longer be routed to it.
 
Resolving the problem
The most effective way to handle this issue is to manually remove the cluster member name from the primary server list. This takes it out of the listing of available cluster members and the plug-in will no longer see it as a viable option.
Before you manually change anything within the plugin-cfg.xml file, it is recommended that you make a back up copy.

There are 2 ways that you can remove the cluster member form the Primary Server listing:
  • Delete the line in question.

  • Comment out the cluster member line. To comment out an XML line, you need to use the following syntax:

    <!-- comment -->

    Based on the preceding syntax, your listing would look like the following:

    <PrimaryServers>
      <!--<Server Name="cluster_member_1"/>-->
      <Server Name="cluster_member_2"/>
    </PrimaryServers>
