原创：oracle10G 的ORA-12505问题解决方法

今天在开发一个关于**的一个项目时候,本人在使用PLSQL连接oracle的时候一切正常，但是在Myeclipse的DB试图中我一直在使用的URL是如下代码:

 

jdbc:oracle:thin:@127.0.0.1:1521:jdbh

 

 就始终出现如下错误信息：

java.sql.SQLException:Listener refused the connection with the following error:

ORA-12505,TNS:listener does not currently know of SID given in connect descriptor

TheConnection descriptor used by the client was:

localhost:1521:jdbh

在网上也看了一些资料也都没有说到具体解决的办法，现将个人的总结如下:

 

解决方法:

    首先打开你的D:\oracle\product\10.2.0\db_1\NETWORK\ADMIN路径下的:tnsnames.ora文件看以下代码,本人的代码如下:

# tnsnames.ora Network Configuration File: D:\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = RedArmychen-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)

大家看到我标准的红色字体了吗?(SERVICE_NAME = orcl)那么你只需要 修改连接的URL地址为 :

jdbc:oracle:thin:@127.0.0.1:1521:orcl

即可解决问题 ,这只限于个人 遇到错误的解决方法 !如果还有异常请耐心解决吧 。
