Hi Theo,

Since you are using static membership and NOT
dynamic(multi-cast) which auto-detect members, my current
understanding says that you will have to add entry of all the
members of your cluster in each of nodes server.xml. Example:

My cluster has two nodes. So to configure these I had add these
two members entries in both node's server.xml(since running on
the same machine, they have varying port with same ip):

Interceptor
className=org.apache.catalina.tribes.group.interceptors.
StaticMembershipInterceptor Member
className=org.apache.catalina.tribes.membership.StaticMember

Hello,


I am trying to setup a simple Tomcat cluster with static
membership. I can't use multicast because I am on a
virtualization environment that does not allow it.

Debian 7 Tomcat 8.0.14 Oracle JVM 1.8.0_25

Both Tomcat are ok on their own, but I can't seem to make the
clustering work: the sessions are not replicated from one to
another. Following the official documentation, I wrote this
configuration :

Engine name=Catalina defaultHost=localhost Cluster

Note: I changed the host and uniqId on the
StaticMembershipInterceptor on the other Tomcat.

This is not a network problem as I can telnet into the 4110
port from one server to another. Also, by running a tcpdump,
I can't see any trafic between the two servers.

The Tomcats seem to be doing something, because I have the

 Mark, things haven't changed on Tomcat8 for the logging properties,
 your configuration did work.
 
 In the end, I had two problems: * My client did not have a
 distributable/ element in his web.xml

This was going to be my suggestion. It's the most obvious thing that
everyone misses.

 * More importantly, the NioReceiver was not well configured.
 
 The address parameter as defined in the documentation 
 (http://tomcat.apache.org/tomcat-8.0-doc/config/cluster-receiver.html)

 
was more that what I thought. It is not only the binding address for the
 receiver, it's also the address that will be advertised to the
 other nodes of the cluster. I configured it to 0.0.0.0,
 therefore the other node tried to connect to 0.0.0.0:port. You
 can see the problem... Replacing this address by a routable one
 solved my problem. Even if it is quite logical, I think the
 documentation could be clearer on this point.

Patches, even to the documentation, are always welcome ;)

Tomcat cluster with static membership

2014-12-08 Thread Théo Chamley 

Hello,

I am trying to setup a simple Tomcat cluster with static membership. I 
can't use multicast because I am on a virtualization environment that 
does not allow it.


Debian 7
Tomcat 8.0.14
Oracle JVM 1.8.0_25

Both Tomcat are ok on their own, but I can't seem to make the clustering 
work: the sessions are not replicated from one to another.

Following the official documentation, I wrote this configuration :

Engine name=Catalina defaultHost=localhost
Cluster 
className=org.apache.catalina.ha.tcp.SimpleTcpCluster
Manager 
className=org.apache.catalina.ha.session.BackupManager

   expireSessionsOnShutdown=false
   notifyListenersOnReplication=true
   mapSendOptions=6/
Channel 
className=org.apache.catalina.tribes.group.GroupChannel
   Receiver 
className=org.apache.catalina.tribes.transport.nio.NioReceiver

  address=0.0.0.0
  port=4110
  selectorTimeout=100
  maxThreads=6/

   Interceptor 
className=org.apache.catalina.tribes.group.interceptors.StaticMembershipInterceptor
  Member 
className=org.apache.catalina.tribes.membership.StaticMember

  port=4110
  host=my.server.1
  domain=staging-cluster
  
uniqueId={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,0}/

   /Interceptor

   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/
   Interceptor 
className=org.apache.catalina.tribes.group.interceptors.ThroughputInterceptor/

   /Channel
   Valve 
className=org.apache.catalina.ha.tcp.ReplicationValve

filter=.*\.gif|.*\.js|.*\.jpeg|.*\.jpg|.*\.png|.*\.css|.*\.txt/
   ClusterListener 
className=org.apache.catalina.ha.session.ClusterSessionListener/

/Cluster
[...]
/Engine

Note: I changed the host and uniqId on the StaticMembershipInterceptor 
on the other Tomcat.


This is not a network problem as I can telnet into the 4110 port from 
one server to another.
Also, by running a tcpdump, I can't see any trafic between the two 
servers.


The Tomcats seem to be doing something, because I have the following in 
my catalina.out:

Could someone, please, help me finding what I am doing wrong?

Thanks,

Théo C.

Hi Theo,

Since you are using static membership and NOT dynamic(multi-cast) which
auto-detect members, my current understanding says that you will have to
add entry of all the members of your cluster in each of nodes server.xml.
Example:

My cluster has two nodes. So to configure these I had add these two members
entries in both node's server.xml(since running on the same machine, they
have varying port with same ip):

  Interceptor
className=org.apache.catalina.tribes.group.interceptors.StaticMembershipInterceptor
Member
className=org.apache.catalina.tribes.membership.StaticMember
port=4000
host=192.168.1.6
uniqueId={10,1,0,100,0,0,0,0,0,0,0,0,0,0,0,0}/

Member
className=org.apache.catalina.tribes.membership.StaticMember
port=4001
host=192.168.1.6
uniqueId={10,1,0,101,0,0,0,0,0,0,0,0,0,0,0,0}/

Ameer Mawia
