1.查看监听程序是否启动

打开cmd窗口，cmd用管理员运行，否则无法执行启动与停止监听命令

lsnrctl status查看运行状态

lsnrctl stop停止监听

lsnrctl start启动监听

执行停止监听命令

2.修改监听配置文件

 

a> 打开<OracleHome>/network/admin/listener.ora文件，找到：

   SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\app\glass\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:C:\app\glass\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
   )

GLOBAL_DBNAME全局数据库默认为orcl.hostname，安装数据库时配置

  b> 添加：
            (SID_DESC =
       (GLOBAL_DBNAME = ORCL.16.167.16)需要修改
       (ORACLE_HOME = C:\app\glass\product\11.2.0\dbhome_1)  
       (SID_NAME = ORCL)需要修改
      )

c> 修改后的配置文件如下

# listener.ora Network Configuration File: C:\app\glass\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\app\glass\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\glass\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
 
  (SID_DESC =
       (GLOBAL_DBNAME = ORCL.16.167.16)
       (ORACLE_HOME = C:\app\glass\product\11.2.0\dbhome_1) 
       (SID_NAME = ORCL)
      )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.167.16)(PORT = 1521))
    )
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    )
  )

 

ADR_BASE_LISTENER = C:\app\glass

 

注意：配置文件中配置的ip必须为有效的ip，否则无法启动，如果电脑ip不固定，变化ip后，刚会导致oracle监听无法启动，可根据需要自己配置，若只在本机上使用，可只保留127.0.0.1的ip，这样不管是否连网，都能顺利启动监听程序
