无法从Web应用程序连接一致性集群 [英] Not able to connect coherence cluster from web application

问题描述

我有一个在Websphere应用程序服务器8.5上运行的Web应用程序.我在WebLogic上运行了一致性群集服务器.我想连接此Web应用程序以加入一致性集群.我得到错误提示:

I have a web application which is running on Websphere application server 8.5. I have coherence cluster server running on the WebLogic. I want to connect this web application to join the coherence cluster. I get the error shown blow:

以下是我的替代xml文件:

Below is my override xml file:

从该错误中，我可以看到该Web应用程序无法连接到WKA.有人可以帮我解决我无法连接的问题吗?我已验证群集已启动& ;；运行中.

From the error, I can see that the web application is not able to connect to the WKA. Can some one help me on what could be cause that I am not able to connect? I have verified that the cluster is up & running.

推荐答案

您必须在Weblogic和Websphere服务器的启动脚本中将主机和端口作为JVM参数传递，前提是必须同时存在所有JVM的计算机.彼此之间有适当的联系. JVM参数应同时包含weblogic和webshpere主机和端口.这样，两个服务器都可以从JVM识别其他成员.参数示例:

You need to pass the hosts and ports as JVM arguments in the startup script of both Weblogic and websphere server provided both the machines where all the JVM are present, must have proper connection each other. JVM arguments should contain both weblogic and webshpere hosts and ports. So that, both servers can identify the other members from JVMs. Example arguments:

COHERENCE_L_HOST="-Dtangosol.coherence.localhost=localhost"
COHERENCE_L_PORT="-Dtangosol.coherence.localport=8080"
COHERENCE_W_HOST1="-Dtangosol.coherence.wka.host.1=localhost"
COHERENCE_W_PORT1="-Dtangosol.coherence.wka.port.1=8085"
COHERENCE_W_HOST2="-Dtangosol.coherence.wka.host.2=localhost"
COHERENCE_W_PORT2="-Dtangosol.coherence.wka.port.2=8089"
COHERENCE_W_HOST3="-Dtangosol.coherence.wka.host.3=localhost"
COHERENCE_W_PORT3="-Dtangosol.coherence.wka.port.3=8090"
