Weblogic创建channel

如果创建域的开始阶段没有为AdminServer指定绑定地址，那么weblogic遍历所在主机的所有IP地址。每一个IP地址创建一个ServerSocket，也就是我们在界面上看到channel,比如以下输出：

<2012-8-13 下午06时32分39秒 CST> <Error> <Server> <BEA-002606> <Unable to create a server socket for listening on channe
l "Default[4]". The address fe80:0:0:0:0:0:0:1 might be incorrect or another process is using port 7001: java.net.BindEx

<2012-8-13 下午06时32分39秒 CST> <Notice> <Server> <BEA-002613> <Channel "Default[6]" is now listening on 127.0.0.1:7001

从上面的输出可以看到，总共有7个channel，有的绑定成功，有的失败：

1. fe80:0:0:0:0:0:0:1 :                    Default[4]

2. fe80:0:0:0:224:1dff:fe2a:689a  Default[3]

3. fe80:0:0:0:0:ffff:ffff:fffd            Default[2]

4. fe80:0:0:0:0:5efe:c0a8:13e        Default[1]

5. 192.168.1.62                            Default/Default[0]

6. 127.0.0.1                                  Default[6]

7. 0:0:0:0:0:0:0:1                           Default[5]

我们罗列一下机器的IP地址：

public static void main(String[] args) throws IOException {
        Enumeration<NetworkInterface> eni = NetworkInterface.getNetworkInterfaces();
        while(eni.hasMoreElements()){
            NetworkInterface ni = eni.nextElement();
            Enumeration<InetAddress> eIa = ni.getInetAddresses();
            while(eIa.hasMoreElements()){
                System.out.println(eIa.nextElement().getHostName());
            }
        }
    }
