最近在升级Oralce Weblogic server 的时候总碰到错误：

网上解决方案纵说纷纭，又说权限问题的，又说端口错误问题的，最后得出官方解决方案如下：

startmanagedweblogic UCM_server1 http://<adminservername>:<port>

where <adminservername> = Servername or IP Address of the WebLogic Server
where <port> = the port number of the WebLogic Admin Server for the domain

*This instruction assumes the Administration Server has been started prior to startup of the managed server, which is a requirement.
