遇到一个问题，今天折腾了半个多小时，不注意细节，真是

 

无非原因有两个

1、服务没有启动

这个原因大家很容易知晓

 

2、链接监听不对

明明使用as sysdba可以链接，后边加上·服务名就不行，刚开始查找网上资料，神什么原因都有，最后自己最琢磨了下细心看了监听

一个是

Services Summary...
Service "orcl" has 1 instance(s).
  Instance "ORCL", status UNKNOWN, has 1 handler(s) for this service...
Service "orcl.localdomain" has 1 instance(s).

将服务名改修改一下就ok了
