Oracle启动监听报错：The listener supports no services解决

mahan

进入服务器切换到oracle用户查看监听状态提示如下：
[oracle@db01 ~]$ lsnrctl status

TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
  TNS-00511: No listener
   Linux Error: 2: No such file or directory
提示没有监听服务

问题原因：数据库实例没注册到listener

解决办法：

登陆数据库
sqlplus / as sysdba

显示服务名
SQL> show parameter service_names

NAME                                     TYPE         VALUE
------------------------------------ ----------- ------------------------------
service_names                             string         orcl


强制注册服务

SQL> alter system register;
