oracle 11g The listener supports no services 一例

测试环境，遇到错误如下：

ORA-12505: TNS:listener does not currently know of SID given in connect

本机连接，SID确信是对的，于是查看监听：

The listener supports no services

修改hostname，alter system register都不行。

后来修改 listener.ora,加入如下内容：

SID_LIST_LISTENER = 
(SID_LIST = 
  (SID_DESC = 
  (GLOBAL_DBNAME = aaa)
  (SID_NAME = aaa)
  )
)

重启监听，OK。
