Clusterning infinispan nodes

[anky]

Hi All,

I am trying to create the 3 nodes cluster and following the source code available on link https://github.com/infinispan/infinispan-quickstart/tree/master/clustered-cache  but the nodes are not able to communicate with each other.

We are using the 6.0 version of infinispan.

Below is the jgroups.xml file:

<config xmlns="urn:org:jgroups"

        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        xsi:schemaLocation="urn:org:jgroups http://www.jgroups.org/schema/JGroups-3.4.xsd">

   <UDP

         mcast_port="${jgroups.udp.mcast_port:8661}"

         ucast_recv_buf_size="20m"

         />

   <FD_SOCK/>

   <MFC max_credits="2m" min_threshold="0.40"/>

   <FRAG2 frag_size="60k" />

</config>

Hi Ankit,

Do you have any exception or more information that you can provide?

The most common problem is the nodes are not unable to find each other. Since you are using IP multicast as discover mechanism, take a look in here: http://jgroups.org/manual/html/ch02.html#ItDoesntWork .

If your cluster does not support IP multicast, you have to configure another discover mechanism. You can find info about it in here: http://jgroups.org/manual/html/protlist.html#DiscoveryProtocols

If you need help let me know.

Cheers,

Pedro
