一、监听问题描述

最近在迁移一个oracle数据库时，监听启动oracle监听程序时报如下错误，监听The 监听listener supports no services，二、源码库监听原因分析

数据库实例没注册到listener

三、监听处理过程

在listener.ora里面添加了红色标记的监听代码，具体如下：

oracle@oracle11g admin]$ cat listener.ora

# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora

# Generated by Oracle configuration tools.

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

(ADDRESS = (PROTOCOL = TCP)(HOST = oracle11g)(PORT = 1521))

)

)

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME = orcl)

(SID_NAME = orcl)

)

)

ADR_BASE_LISTENER = /u01/app/oracle

注：根据实际情况把GLOBAL_DBNAME及SID_NAME的亿华云监听值换成自己数据库实际的值即可。
