有配置过weblogic10的cluster的达人吗?求教下问题啊,谢谢!~~~~

Question

我在linuxas4下安了一个weblogic10中文版,并且同一个服务器下见了2个节点服务器,分别是test1_1和test1_2,test1_1的监听端口:8001,ssl端口:9001,test1_2的监听端口:8002,ssl端口:9002;管理服务器的端口:7001.我不做cluster的情况下,2个服务器都可以正常启动,但是在做cluster的时候,选择群集消息传递模式为多播的情况下,我的这2个节点服务器就不能启动了,但是我做单播的情况,这2个服务器却能起来,不知道这个是怎么回事!希望高手能给指点一二!谢谢!~~~~以下是我在做test1_1的启动失败时,帖的log,能帮我分析一下吗?谢谢!~~~
