Oracle问题之ORA-12560TNS:协议适配器错误

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

 6     (SID_DESC =

 8       (ORACLE_HOME = D:\install\oracle\oracle-install\product\11.2.0\dbhome_1)
 9       (PROGRAM = extproc)
10       (ENVS = "EXTPROC_DLLS=ONLY:D:\install\oracle\oracle-install\product\11.2.0\dbhome_1\bin\oraclr11.dll")
11     )
12     (SID_DESC =
13       (SID_NAME = BOOKSALES)
14       (ORACLE_HOME = D:\install\oracle\oracle-install\product\11.2.0\dbhome_1)
15    (GLOBAL_DBNAME = BOOKSALES)
16  )
17   )
18 
19 LISTENER =
20   (DESCRIPTION_LIST =
21     (DESCRIPTION =
22       (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
23     (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100)(PORT = 1521))
24     (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
25     (ADDRESS = (PROTOCOL = TCP)(HOST = acer)(PORT = 1521))
26     )
27   )

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

 5   (DESCRIPTION =
 6     (ADDRESS_LIST =
 7       (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100)(PORT = 1521))
 8     )
 9     (CONNECT_DATA =
10       (SERVICE_NAME = BOOKSALES)
11     )
12   )
View Code

   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
