Coherence : weblogic.application.ModuleException: No storage-enabled nodes exist for service DistributedSessions

Question

I am trying to use Coherence server (separate from my client to store session data) for my weblogic server (client). I'm getting the error like

weblogic.application.ModuleException: No storage-enabled nodes exist for service DistributedSessions:com.tangosol.net.RequestPolicyException:No storage-enabled nodes exist for service DistributedSessions

Similar question was asked in past in the forum and i have verified all the threads and not able to find the right solution.

Can someone please help?

1) Config on Coherence Server: Keep tangosol-coherence-override on the Coherence server class path.

2) Sample of xml file:

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE coherence SYSTEM "coherence.dtd">
<coherence>
    <cluster-config>
        <member-identity>
            <cluster-name>ClusterName</cluster-name>
        </member-identity>
        <unicast-listener>
            <address system-property='tangosol.coherence.localhost' />
            <port system-property='tangosol.coherence.localport'>18088</port>
            <well-known-addresses>
                <socket-address id='1'>
                    <address>830.8.119.55</address>
                    <port>18088</port>
                </socket-address>               
            </well-known-addresses>
        </unicast-listener>
        <shutdown-listener>
            <enabled system-property='tangosol.coherence.shutdownhook'>none</enabled>
        </shutdown-listener>
        <logging-config>
            <destination system-property='tangosol.coherence.log'>log4j</destination>
        </logging-config>
    </cluster-config>
</coherence>

3) Start the coherence Server with command java -server -Xms1024m -Xmx1024m -cp ${COHERENCE_HOME}/../lib/coherence.jar:${COHERENCE_HOME}/../lib/coherence-web.jar:${COHERENCE_HOME}/../config/ -Dtangosol.coherence.session.localstorage=true com.tangosol.net.DefaultCacheServer 1> ${COHERENCE_HOME}/../logs/stdlog.log 2>&1 &

4) Output on coherence server startup

**Started DefaultCacheServer...**

5) Starting the Weblogic server along with other command line argument provide following -Dtangosol.coherence.session.localstorage=false so weblogic will store the session data on coherence server and not the local weblogic heap.

6) Kept the same tangosol-coherence-override.xml file on weblogic class path

7) Able to start the weblogic server

8) When deploying the webapplication I can see weblogic client has joined the cluster but deployment fails 2017-10-09 10:30:48.321/648.794 Oracle Coherence GE 3.7.1.16 <D5> (thread=Cluster, member=1): Member(Id=2, Timestamp=2017-10-09 10:30:48.149, Address=830.8.119.55:18090, MachineId=65067, Location=site:,machine:abcdv6413,process:28222, Role=WeblogicServer) joined Cluster with senior member 1 2017-10-09 10:30:48.655/649.128 Oracle Coherence GE 3.7.1.16 <D5> (thread=Cluster, member=1): Member 2 joined Service Management with senior member 1 2017-10-09 10:30:49.077/649.550 Oracle Coherence GE 3.7.1.16 <D5> (thread=Cluster, member=1): Member 2 joined Service DistributedSessions with senior member 2

But deployment fails with

weblogic.application.ModuleException: No storage-enabled nodes exist for service DistributedSessions:com.tangosol.net.RequestPolicyException:No storage-enabled nodes exist for service DistributedSessions

On weblogic server i have installed coherence-web-spi.war as library and also specificy lib-ref in weblogic.xml

I'm not sure what I am missing.

Answer 1

In your configuration file you have to insert all address of your architecture: weblogic server (datastorage=false) and the coherence server:

<well-known-addresses>
    <socket-address id='1'>
        <address>830.8.119.55</address>
        <port>18088</port>
    </socket-address>   
    <socket-address id='2'>
        <address>x.x.x.x</address>
        <port>yyy</port>
    </socket-address>              
</well-known-addresses>
