I am new to Tomcat 6 (upgrading from Tomcat 4) and I would love to benefit from
the features of clustering. However, I am concerned about performance. Are
people successfully using the clustering features of Tomcat 6 in production?
If so, are your settings a lot different than mine:
<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
channelSendOptions="8" > <Manager
className="org.apache.catalina.ha.session.DeltaManager"
expireSessionsOnShutdown="false" notifyListenersOnReplication="true"/>
<Channel className="org.apache.catalina.tribes.group.GroupChannel">
<Membership
className="org.apache.catalina.tribes.membership.McastService"
address="228.0.0.4" port="45564"
frequency="500"
dropTime="3000"/> <Receiver
className="org.apache.catalina.tribes.transport.nio.NioReceiver"
address="127.0.0.1" port="4010"
autoBind="100"
selectorTimeout="5000" maxThreads="6"/>
<Sender
className="org.apache.catalina.tribes.transport.ReplicationTransmitter">
<Transport
className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>
</Sender> <Interceptor
className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
<Interceptor
className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>
</Channel> <Valve
className="org.apache.catalina.ha.tcp.ReplicationValve" filter=""/>
<Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>
<ClusterListener
className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>
<ClusterListener
className="org.apache.catalina.ha.session.ClusterSessionListener"/>
</Cluster>
I'd love to hear any performance tips people have.
Thanks,Jim
