【问题描述】：
我正在尝试将 Coherence 服务器（与我的客户端分开来存储会话数据）用于我的 weblogic 服务器（客户端）。我收到类似的错误
weblogic.application.ModuleException: No storage-enabled nodes exist for service DistributedSessions:com.tangosol.net.RequestPolicyException:No storage-enabled nodes exist for service DistributedSessions
以前在论坛上问过类似的问题，我已经验证了所有线程，但无法找到正确的解决方案。
有人可以帮忙吗？
1) Coherence 服务器上的配置：Keep tangosol-coherence-override on the Coherence server class path.
2) xml文件示例：
<?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) 使用命令启动 coherence Server
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) coherence 服务器启动时的输出

**Started DefaultCacheServer...**
5) 启动 Weblogic 服务器
连同其他命令行参数提供以下
-Dtangosol.coherence.session.localstorage=false
所以 weblogic 会将会话数据存储在 coherence 服务器上，而不是本地 weblogic 堆上。
6) 在 weblogic 类路径上保留相同的 tangosol-coherence-override.xml 文件
7) 能够启动weblogic服务器
8) 部署 web 应用程序时，我可以看到 weblogic 客户端已加入集群，但部署失败

但是部署失败了
weblogic.application.ModuleException: No storage-enabled nodes exist for service DistributedSessions:com.tangosol.net.RequestPolicyException:No storage-enabled nodes exist for service DistributedSessions
在 weblogic 服务器上，我已将 coherence-web-spi.war 作为库安装，并在 weblogic.xml 中指定了 lib-ref
我不确定我错过了什么。
