对WebSphere6的某一参数修改后，重启服务，想查看修改的效果，结果修改前后没变化，于是怀疑是否重新启动成功，查看日志，果真出问题了：

异常的关键在于这一句：
异常 com.ibm.websphere.management.exception.ConnectorException: ADMC0053E: 启用 SOAP 连接器安全性时，系统无法创建连接到端口 8880 上的主机 whale 的 SOAP 连接器。
启用SOAP连接器安全性验证后，WAS会通过SOAP_CONNECTOR_ADDRESS设置的端口来验证安全性，这个端口设置是在 "服务器---应用程序服务器---server---端口"部分操作，查看第二列的名字是否与你的主机名字相同，
最后说下解决方案：
Window：在C:\WINDOWS\system32\drivers\etc目录下的Hosts中添加你的IP和之前的主机名就可以了（或者改成你的IP和localhost）
eg：
127.0.0.1 whale
127.0.0.1 localhost
Linux同理，文件位置在 /etc/hosts文件下。
修改后，如果是在window下关闭并重新启动websphere服务，会在cmd命令下提示把安全验证加入安全列表什么的，选择Y,然后会弹出一个窗体，第一行忽视，默认即可，第二行和第三行分别输入websphere登陆的用户名和密码，over。
