报错信息

在启动oracle监听的时候，提示The listener supports no services。如下：

[oracle@root bin]$ lsnrctl start

客户端信息

这时候，远程连接oracle就会报错ora-12514:TNS: 无法解析指定的连接标识符.

问题原因

根据lnstctl 提示信息，说明：数据实例没有注册到监听器上。

解决办法一

在listener.ora里面添加监听的实例名，属于静态注册监听实例。

[oracle@dbserver admin]$ vi listener.ora 
# listener.ora Network Configuration File: /home/app/oracle/product/11.2.0.4/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = dbserver)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = /home/app

INBOUND_CONNECT_TIMEOUT_listenername=0

# 添加实例名
SID_LIST_LISTENER = 
    (SID_LIST =
            (SID_DESC =
                    (GLOBAL_DBNAME = orcl)
                    (SID_NAME = orcl)
            )
    )

解决办法二

通过sqlplus登录后，动态注册监听实例。

[oracle@dbserver ~]$ sqlplus / as sysdba

重启监听程序

[oracle@dbserver bin]$ $ORACLE_HOME/bin/lnsrctl reload

在通过远程连接oracle就可以正常连接上了。
