ora-12170连接超时解决方案
关键字: ora-12170
本人在本机装了oracle服务都启动了，但是到了别的机器就不能连接老报ora-12170的连接超时的错误，后来发现在oracle服务器端的防火墙吧1521端口封了，把它在windows添加开放1521的端口就好了

看附件图片，截图了。
对了如果还不行，就重新启动机器一下。

Ora-12514和Ora-12514解决方法,阅读实例讲解Ora-12514和Ora-12514解决方法,错误现象：Oralce数据库服务启动后，出现了下面的问题： OracleOraDb10g_home1TNSListener： 该服务对应 %Oracle_Hoem\bin TNSLSNR.EXE 若该服务未启动，将会导致Oracle错误- 错误现象：Oralce数据库服务启动后，出现了下面的问题：
OracleOraDb10g_home1TNSListener：

该服务对应 %Oracle_Hoem\bin TNSLSNR.EXE

若该服务未启动，将会导致Oracle错误- Ora-12514：TNS：无监听程序。


OracleServiceORACLE:

若该服务未启动，将会导致Oracle错误- Ora-12514：TNS：监听程序当前无法识别链接描述符中请求的服务。

注释：启动了该服务也有可能导致该错误。

下面我们来介绍一下具体的解决方法：


打开：%Oracle_Hoem%/network/admin/listener.ora文件

在

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = D:\Oracle\Oracle10g)

(PROGRAM = extproc)

)

后面添加：

(SID_DESC =

(GLOBAL_DBNAME = ORACLE)

(ORACLE_HOME = D:\Oracle\Oracle10g)

(SID_NAME = ORACLE)

)


最后变成：

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = D:\Oracle\Oracle10g)

(PROGRAM = extproc)

) (SID_DESC =

(GLOBAL_DBNAME = ORACLE)

(ORACLE_HOME = D:\Oracle\Oracle10g)

(SID_NAME = ORACLE)

)

)
