ORA-12505, TNS:监听器当前不知道连接描述符中给定的SID

我已经在我的windows 7 64位操作系统中安装了Oracle 11g Express Edition Release 2，并试图执行JDBC程序，然后我得到了以下错误:

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

我通过纠正JDBC代码解决了这个问题。

正确的JDBC字符串应该是…

conection = DriverManager.getConnection
("jdbc:oracle:thin:@localhost:1521:xe","system","ishantyagi");

但是我使用的JDBC字符串是…

conection = DriverManager.getConnection
("jdbc:oracle:thin:@localhost:1521:orcl","system","ishantyagi");

因此，指定orcl而不是xe的错误显示了这个错误，因为SID名称是错误的。

其他回答

如果您在Oracle SQL Developer中有一个工作连接，请使用连接菜单上的信息来构建您的url，如下图所示:

在上面的例子中，url将是:jdbc:oracle:thin:@ORADEV.myserver.com:1521/myservice

注意，如果您使用的是SID，那么在主机名后面有一个冒号(“:”)而不是斜杠(“/”)。

I too faced the same issue. I had installed Oracle Express edition 10g in Windows XP OS using VMware and it was working fine. Since it was very awkward typing SQL queries in the SQL utility provided by 10g and since I was used to working with SQL developer, I installed 32 bit SQL developer in XP and tried connecting to my DB SID "XE". But the connection failed with error-ORA-12505 TNS listener doesn't currently know of SID given in connect descriptor. I was at sea as to how this problem occurred since it was working fine with the SQL utility and I had also created few Informatica mappings using the same. I did browse a lot on this stuff hither thither and applied the suggestions offered to me after pinging the status of "lsnrctl" on public forums but to no avail. However, this morning I tried creating a new connection again, and Voila, it worked with no issues. I am guessing after reading in few posts that sometimes listener listens before the DB connects or something(pardon me for my crude reference as I am a newbie here) but I suggest to just restart the machine and check again.

连接con = DriverManager.getConnection (" jdbc: oracle:薄:@localhost: 1521: xe”,“斯科特”、“老虎”);

我得到的错误:

java.sql.SQLException:监听器拒绝连接，错误如下: ORA-12505, TNS:监听器当前不知道连接描述符中给定的SID 客户端使用的连接描述符是: localhost: 1521: xe

我是怎么解决的:

连接con = DriverManager.getConnection (" jdbc: oracle:薄:localhost: 1521: xe”,“斯科特”、“老虎”);

(删除@)

不知道为什么，但它现在工作了…

Oracle: 精简样式的服务名称语法

只有JDBC Thin驱动程序支持精简样式的服务名称。语法为:

/ service_name @ / / host_name: port_number进行
