Hi.

This is for the Tomcat/Tribes experts on the list.

I know nothing of Tribes, but the on-line documentation seems to say that the communication happens over TCP and that the protocol used is not encrypted. Fady previously tried a standard "ping" and a "telnet" between the two nodes, and that is the base for him mentioning that "there is no network disconnection" between the nodes. Nevertheless, the calling pinging node seems to say that it times out without getting a response fom the target node. There is evidently a contradiction there.
So this could still be some kind of network issue.

Considering that the protocol command for this "ping" should be known by someone here, would it not be possible to imagine a little program in some scripting language (or even java, God forbid), which would open a TCP channel with the target node IP/port, send such a "ping" message, wait for a response and report the result ?
That would at least confirm/deny that the problem is with the network.

The log below does not for example say if the error happens when opening the TCP communication channel, or after sending the ping message on it, (Of course, testing the TCP open could be done with "telnet IP 4000", but I don't know if Fady tried this).
Maybe tribes also already contains some löw-level debugging options ?
wireshark maybe another option, but it has quite a learning curve.
And this is on Windows.

By the way Fady, are you sure that your "Windows Firewall with Enhanced Security" is not just dropping TCP packets to/from port 40xx (or from "java.exe") ? There are some "network policies" there which can have wide-ranging side-effects.

Fady,

Sorry for top posting.

If I remember correctly, the Cluster Element goes into the Container and not 
the Host.
Plus I see in our (working) case, a DeltaManager and a 
JvmRouteSessionIDBinderListener

         <Manager className="org.apache.catalina.ha.session.DeltaManager"
                    expireSessionsOnShutdown="false"
                    notifyListenersOnReplication="true"/>
...
         <ClusterListener 
className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>

Besides this, only ports, limits and values are different.

You may want to filter out the replication for static resources as gifs jpg or 
css.
         <Valve className="org.apache.catalina.ha.tcp.ReplicationValve" 
filter=".*\.gif;.*\.js;.*\.jpg;.*\.png;.*\.htm;.*\.html;.*\.css;.*\.txt;" />

Best regards

Peter

below is the server.xml configuration, as mentioened earlier the issue
is related to the cluster configuration, and as per my research i can
see that some users are facing the same issue but i didnt  found the
solution of it

I still don't know tribes, but then my non-educated guess at this point
would be that there is something wrong in your configuration.
Can you copy/paste it here ? (remove sensible things like passwords, public
IP addresses etc..)(but not to the point of making it uncheckable).

Then maybe some tribes-specialist can take over ?



Is there actually something listening on that address/port ? Tomcat
cluster

the Port 4000 is listening and there is no disconnection between 2

Hi.
If you want quick answers, you should provide more information.
What is the host OS ?
What is the Tomcat version ?
Is this problem new ? was this working before ? how long ?

I do not know tribes at all, but according to the logfile below, it seems
that something is trying to "ping" the address 10.114.43.103, port 4000,
and
never getting a response (or at least not within 3000ms).
Is there actually something listening on that address/port ?
The "netstat" command (available both on Linux and Windows) can tell you.
If there is something listening there, can it respond to whatever is
ping-ing it ?
(routing, firewall, ..)
