tomcat simple cluster

[micou94]

Hi,

i develop an application for a server tomcat and actually i would like a simple cache cluster between two tomcat server (machine A and B).

i try to make cluster local and it work very good but when it is two different machine and i think it is due to a config xml, i do not know.

i saw this tutorial http://community.jboss.org/wiki/settingupaninfinispancluster but it doesn't solve my problem.

i try to make a simple programme :

it is very simple but it works with 2 JVM cluster in local.

    private    Cache cache = null;  
    private    EmbeddedCacheManager cm = null;
    private    TreeCache treecache = null;
 
    //init
    public void init()
    {
        try {
            cm = new DefaultCacheManager("../../cache.xml");
        } catch (IOException e1) {
            System.out.println("Cachemanager XML : " + e1.getStackTrack());
        }
        try {
            cache = cm.getCache();
        }
        catch(Throwable e){
            System.out.println("getcache error or XML: " + e.getStackTrace());
        }
        try{
            treecache = new TreeCacheFactory().createTreeCache(cache);
        }
        catch(Throwable e){
            System.out.println("Creation du treecache: "+e.toString());
        }
        treecache.start();    
}

i give you my cache.xml and my jgroups-tcp.xml, i hope you can help me because i want a simple utilisation of infinispan between two machine and it is doesnt work, i think because i got a little mistake and i did not see ;/

when i launch my two tomcat with my api nothing append, they work but they do not have cluster.

1- is it a problem with conf tomcat xml ?

2- is it a problem with cache or jgroups-tcp xml ?

thanks for your help

hi,

i had this configuration actually:

|========|

| tomcat A  |

| tomcat B  |

|========|

server one

|========|

| tomcat A  |

| tomcat B  |

|========|

server two

all tomcat is clustered and logs is good.

-cache infinispan tomcat A is clustered with cache infinispan tomcat B and it is ok.

-cache infinispan tomcat C is clustered with cache infinispan tomcat D and it is ok.

So i think cache.xml did not take jgroups-tcp.xml configuration i do not have warning in log about it.

i think he doesnt take parameter in TCPPING with my all ip:port.

And it is normal when un write wrong paramettre XML in jgroups-tcp i do not have Exception ?

for this configuration i had:

      <TCPPING initial_hosts="10.112.179.165[7800], 10.112.179.165[7801], 10.112.179.181[7800]， 10.112.179.181[7801] "

           port_range="5"

             timeout="3000"

             num_initial_members="4"></TCPPING>

thanks for you help

Did you try using UDP instead of TCP, if your environment supports UDP multicast?

[mircea.markus]

as per yor jgroups-tcp.xml you bind the servers on port 7882:

   <TCP

                    bind_addr="10.112.179.165"

                    start_port="7882"

The discovery (TCPPING) should also try to run in the same range, i.e. 7880 and not 7800.

I can't see how the cluster forms even on the same machine..
