Oracle协议适配器错误解决办法
在Oracle中新建了一个数据库,今天把它删了之后再登录SQL*PLUS就登不上去了,出现ORA-12560:TNS:协议适配器错误。ORA-12560: TNS
在Oracle中新建了一个数据库,今天把它删了之后再登录SQL*PLUS就登不上去了,出现ORA-12560:TNS:协议适配器错误。
ORA-12560: TNS: 协议适配器错误的解决方法
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oraclehome92TNSlistener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oracleserviceXXXX,XXXX就是你的database SID.
3.注册表问题。regedit,然后进入HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\HOME0将该环境变量ORACLE_SID设置为XXXX,XXXX就是你的database SID.或者右几我的电脑,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,就可以解决问题。
=======================================
1、ORA-12541:TNS:没有监听器
原因:没有启动监听器或者监听器损坏。如果是前者,使用命令net start OracleOraHome81TNSListener(名字可能有出入)即可;如果是后者,则使用“Net8 Configuration
Assistant”工具向导之“监听程序配置”增加一个监听器即可(基本不用写任何信息,一路OK。在添加之前可能需要把所有的监听器先删除!)
2、ORA-12500:TNS:监听程序无法启动专用服务器进程或ORA-12560:TNS:协议适配器错误
原因:ORACLE的数据库服务没有启动。使用命令net start ORACLESERVICEORADB(ORADB为数据库名字)即可。如果仍没有解决,请继续向下看。
3、如果数据库服务启动失败,则很有可能是其注册表项值损坏,最好的做法是以下两步:
1)ORADIM -DELETE -SID oradb 删除数据库服务项
2)ORADIM -NEW -SID oradb 新增数据库服务项
注:这个过程中如果出错,就重启计算机!
4、ORA-12154:TNS:能解析服务名
原因:ORACLE的网络服务名没有正确配置。请使用“Net8 Configuration Assistant”工具向导之“本地网络服务名配置”配置TNS即可。如果仍没有解决,请继续向下看。
5、ORA-1034 :TNS:ORACLE不可用
原因:ORACLE的数据库服务正确启动,但是数据库没有打开!
使用命令:
1)svrmgrl 启动服务管理器
2)connect internal 以internal身份登陆
3)startup 打开数据库
6、ORA-12560:TNS:协议适配器错误(顽固性的)
原因:未知。
解决:必杀技--打开“Windows任务管理器”,杀死ORACLE.exe及ORADIM.exe进程,书写自己的
ora_startup.bat,执行之!
PS:
1、我的ora_startup.bat:
net start OracleOraHome81TNSListener
net start ORACLESERVICEORADB
svrmgrl 一般情况下不用,不过有时少不了它的,具体步骤见第5步。
2、我的ora_shutdown.bat:
net stop OracleOraHome81TNSListener
net stop ORACLESERVICEORADB
