Case

I introduced an Oracle Coherence cache withing my application, which is deployed as a WAR within WebLogic  Server. In a first step, I used an instance of Oracle Coherence / Coherence Web already built in WebLogic. Then, for a couple a reasons, I detroyed the Coherence cluster. Deploying the application, the following error appeared:

java.lang.RuntimeException: Failed to start Service "Cluster" (ServiceState=SERVICE_STOPPED, STATE_ANNOUNCE)

Complete Stacktrace

Explanation and Fix

The Coherence cluster view available in WebLogic server is a view of the Tangosol configuration, available in the files tangosol-coherence*.xml of Coherence’s JAR. To fix the issue, create a file tangosol-coherence-override.xml, in your classpath. Fill the file with a minimum content, such as:

<?xml version='1.0'?>
<!DOCTYPE coherence SYSTEM "coherence.dtd">
<coherence>
    <cluster-config>
        <multicast-listener>
            <time-to-live system-property="tangosol.coherence.ttl">0</time-to-live>
            <join-timeout-milliseconds>3000</join-timeout-milliseconds>
        </multicast-listener>
        <unicast-listener>
            <address>127.0.0.1</address>
            <port>8088</port>
            <port-auto-adjust>true</port-auto-adjust>
            <priority>8</priority>
        </unicast-listener>
        <packet-publisher>
            <packet-delivery>
                <timeout-milliseconds>30000</timeout-milliseconds>
            </packet-delivery>
        </packet-publisher>
        <service-guardian>
            <timeout-milliseconds system-property="tangosol.coherence.guard.timeout">35000</timeout-milliseconds>
        </service-guardian>
    </cluster-config>
    <logging-config>
        <severity-level system-property="tangosol.coherence.log.level">5</severity-level>
        <character-limit system-property="tangosol.coherence.log.limit">0</character-limit>
    </logging-config>
</coherence>

Of course, you can amend and improve the file to match your requirements.
NB: in case your file is ignored by Coherence, override the property tangosol.coherence.override with value tangosol-coherence-override.xml.
