| It has been a long time since I worked on WAS 4.x, but the place where I am working at present is using WAS 4.0.7. We are having a server group with two nodes and from the logs it seems that one of the application server is handling much more load than th
e other. Now, I know that the default load balancing behavior is Round Robin, but for some reason it does not seem to be working. I tried getting help from the WebSphere 4.0 Handbook (sg246176) but there's little information about the plugin in the Redboo
k. There's little information on the web as well. The plugin itself is relatively simple and unlike in WAS 5.0 I don't think it's possible to assign weights to the members of the server group in WAS 4.x (as far as I know.) I am pasting below a part of the
plugin:
<ServerGroup Name="XXX">
- <Server CloneID="10d16mkhp" Name="XXX">
<Transport Hostname="X" Port="9081" Protocol="http" />
</Server>
- <Server CloneID="10v0chmbd" Name="YYY">
<Transport Hostname="Y" Port="9081" Protocol="http" />
</Server>
</ServerGroup>
- <UriGroup Name="M/x.war_URIs">
<Uri Name="/app/*" />
</UriGroup>
<Route ServerGroup="XXX" UriGroup="M/sas.war_URIs" VirtualHostGroup="default_host" />
</Config>
For security reasons, I am not revealing the names of application servers and I have changed the names of the UriGroup.
Would it make any difference if I use the parameter "LoadBalance=Round Robin" explicitly in the plugin? I know that IBM no longer supports WAS 4.x, but any help would be greatly appreciated.
