oracle 监听服务配置

最近在red hat 6.6虚拟机上安装了Oracle 11gR2数据库，安装完毕，使用没有问题，通过主机也可以访问到虚拟机上的数据库。然而，在重新启动虚拟机后，主机无法访问到数据库，提示错误：

PS C:\Users\13842> sqlplus sys/Lijiaman3102700@orcl as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on 星期六 2月 25 16:56:47 2017

ERROR:
ORA-12541: TNS: 无监听程序


请输入用户名:

发现没有监听程序，于是到虚拟机上查看监听器状态，结果如下：

LSNRCTL> status
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521)))
TNS-12541: TNS:no listener
 TNS-12560: TNS:protocol adapter error
  TNS-00511: No listener
   Linux Error: 2: No such file or directory
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))
TNS-12541: TNS:no listener
 TNS-12560: TNS:protocol adapter error
  TNS-00511: No listener
   Linux Error: 111: Connection refused

发现是监听器没有启动，启动即可：

[oracle@localhost Desktop]$ lsnrctl start

  (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=EXTPROC1521)))
  (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521)))
The listener supports no services
The command completed successfully

启动之后，新的问题又出现了，在倒数第2行，提示：The listener support no services。说明Oracle的服务并没有注册到监听器，这时，使用主机上的客户端连接数据库，会提示错误：

ERROR:
ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务

接下来配置监听服务信息，在虚拟机上打开网络管理界面：

[oracle@localhost Desktop]$ netmgr

出现如下界面，点击Local->Listeners->Listener->Database Services->Add Database：

三个参数设置：

· Global Database Name:

SQL> select * from global_name;

GLOBAL_NAME
--------------------------------------------------------------------
ORCL

· Oracle Home Dictionary: Oracle安装路径，一般为：../app/oracle/product/11.2.0/dbhome_1

· SID：默认ORCL

点击File->Save network Configuration。

重启数据库，解决。
