I'am not shure that i understand well.
What i whould like to have is session replication on a two members cluster with
unicast heartbeat.
With DisableMcastInterceptor i have no more multicast but no more session
replication. It looks like cluster has no members
Here is my configuration :

yes, that's what you wanted. Then you have to add the static membership
interceptors to add static members since you don't have multicast
heartbeats anymore

Thanks Filip
I added the DisableMcastInterceptor in the cluster configuration wihtout success.
The multicast heartbeat is stopped but there is no more member in the cluster.
DeltaManager::start() loggs Starting clustering manager at ...
but DeltaManager::getAllClusterSessions()loggs : skipping state transfer. No members active in cluster group.
I carry on investigating ....

it is absolutely possible, but now when you mention it, the ability to
not start the multicasting piece has not been exposed. The rest has.
But there is a simple workaround for you, you can create an interceptor,
that traps the start call, and removes the option to start multicasting
it could look like this
package org.apache.catalina.ha.tcp;
import org.apache.catalina.tribes.group.ChannelInterceptorBase;
import org.apache.catalina.tribes.ChannelException;
import org.apache.catalina.tribes.Channel;
public class DisableMcastInterceptor extends ChannelInterceptorBase {
public DisableMcastInterceptor() {
super();
}
public void start(int svc) throws ChannelException {
svc = (svc & (~Channel.MBR_TX_SEQ));
super.start(svc);
}
}
and then, you can have the static membership interceptor to hearbeats
over TCP instead.

Hi all
I would like to know if it is possible to do tomcat 6 clustering without
multicast IP.
In other words by defining a full static cluster in which all the heartbeat
stuff is done by unicast.
If yes please coluld you tel me how to configure it.
I tried a SimpleTcpCluster without McastService declaration and with two
StaticMemberShipInterceptors but my nodes always sends multicast messages on
default address 228.0.0.4.45564
Thanks for help.
