The listener supports no services
The command completed successfully
[oracle@DC04024 ~]$

这样启动后远程连接会造成
oracle ORA-12514:TNS:listener does not currently know of service requested in connect descriptor
*******************************************
* 解决方案一
*******************************************
原因：数据库实例不能注册到listener

--登录数据库
$sqlplus / as sysdba
--显示服务名
sql>show parameter service_names
--强制注册服务
sql>alter system register;
--查看监听状态
$lsnrctl status

*******************************************
* 解决方案二(静态注册)
*******************************************
在listener.ora里面添加了一行

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = globe)
(SID_NAME = globe)
)
)
*******************************************
* 解决方案三(静态注册)
*******************************************

Oracle Net Manager修改配置

在下图的Listeners->Database Services中配置要监听的SID及ORACLE_HOME，退出保存。
