Oracle问题之ORA-12560TNS:协议适配器错误

一、造成ORA-12560: TNS: 协议适配器错误的问题的原因有三个:

1.监听服务没有起起来。windows平台个一如下操作:开始---程序---管理工具---服务,打开服务面板,

  启动OracleOraDb11g_home1TNSlistener服务。
  
  



2.database instance没有起起来。windows平台如下操作:开始---程序---管理工具---服务,打开服务

  面板,启动OracleServiceBOOKSALES, BOOKSALES就是你的database SID    
  



 3.注册表问题。regedit,然后进入HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\HOME

  将该环境变量ORACLE_SID设置为XXXX, XXXX就是你的database SID.
  
  



  



  



  



  或者右击我的电脑,属性--高级--环境变量---系统变量--新建,变量名=oracle_sid,变量值=XXXX, XXXX就是你的database SID.

  或者进入sqlplus前,在command line下输 set oracle_sid=XXXX, XXXX就是你的database SID.

  经过以上步骤,一般就可以解决问题。

二、如果还没有解决的话则会遇到以下问题:

1、执行请求的操作时遇到错误:


IO 错误: The Network Adapter could not establish the connection


供应商代码 17002


2、执行请求的操作时遇到错误:


Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor


供应商代码 12514


三、解决方法如下:

  假如只有一个数据库的话:

  1、找到如下路径:

    D:\install\oracle\oracle-install\product\11.2.0\dbhome_1\NETWORK\ADMIN

    



  2、将文件中的内容修改如下,当然要结合自己的实际情况做简单修改:
     //listener.ora
# listener.ora Network Configuration File: D:\install\oracle\oracle-install\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 = D:\install\oracle\oracle-install\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\install\oracle\oracle-install\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
    (SID_DESC =
      (SID_NAME = BOOKSALES)
      (ORACLE_HOME = D:\install\oracle\oracle-install\product\11.2.0\dbhome_1)
   (GLOBAL_DBNAME = BOOKSALES)
 )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = acer)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = D:\install\oracle\oracle-install

 

     //sqlnet.ora    

# sqlnet.ora Network Configuration File: D:\install\oracle\oracle-install\product\11.2.0\dbhome_1\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.

# This file is actually generated by netca. But if customers choose to 
# install "Software Only", this file wont exist and without the native 
# authentication, they will not be able to connect to the database on NT.

SQLNET.AUTHENTICATION_SERVICES= (NTS)

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

 

     //tnsnames.ora

# tnsnames.ora Network Configuration File: D:\install\oracle\oracle-install\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

BOOKSALES =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = BOOKSALES)
    )
  )

 


   3、重新启动 tnslistener

   4、测试的时候要注意修改对应数据库的用户名和密码

    Oracle SQL Developer连接的时候也要注意用对应的用户名和密码

    

    

    

 

 

 

 

 

 

 

 

执行请求的操作时遇到错误:

IO 错误: The Network Adapter could not establish the connection

供应商代码 17002

 

 

执行请求的操作时遇到错误:

Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor

供应商代码 12514

 

也是按照上面修改配置文件
