部署环境：Weblogic 10 MP2 for UNIX
实验：
Weblogic Cluster: (MServer1,MServer2) 7222
Multicast IP: 239.192.0.0
AdminServer: 192.168.1.33:7001
MServer1: 192.168.1.33:7201
MServer2: 192.168.1.33:7202
Machine1: (MServer1) NodeManager(192.168.1.33:5556)
Machine2: (MServer2) NodeManager(192.168.1.33:5557)
注意：本实验环境各个Server SSL设置---->Hostname Verification: NONE
描述：
（NodeManager 成功启动）
当启动某ManagedServer时分别报以下错误：

分析:依据以下提示，可判断组播地址问题。

查看系统路由表:
[root@localhost ~]# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
缺一条组播239.192.0.0路由
手动添加路由:
[root@localhost ~]# route add -host 239.192.0.0 dev eth0
[root@localhost ~]# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
239.192.0.0 0.0.0.0 255.255.255.255 UH 0 0 0 eth0
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
再启动受控服务器，OK
同样的原因也会导致以下异常抛出：
注意：1. 本实验环境各个Server SSL设置---->Hostname Verification:: BEA HOSTNAME Verifier
2. Weblogic 11gr3(10.3) 不适合此环境
基于SSL环境下 ，成功启动节点管理器后，受控服务器无法正常启动
现象：
当启动MServer_1时，服务器状态：
MServer_1 Machine_1 FAILED_NOT_RESTARTABLE FAILED
NodeManager 报错：

解决方法同上，手动添加组播路由。
