【问题描述】：
我的代码如下。
java.sql.DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
java.sql.Connection con=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe", "ims", "_ims");
异常发生在下面给出的第二行。
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
The Connection descriptor used by the client was:
localhost:1521:xe"
异常是什么意思？我的代码有什么问题？

listener.ora 文件：
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)
(PROGRAM = extproc)
)
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
(ADDRESS = (PROTOCOL = TCP)(HOST = Girish-PC)(PORT = 1521))
)
)
DEFAULT_SERVICE_LISTENER = (XE)
tnsnames.ora 文件：
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Girish-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
)
)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)
上面给出了 tnsnames.ora 和 listener.ora 文件的内容。
【问题讨论】：
-
是
listener.ora文件，在oracle\admin\network下可用。如果可用，请检查port和service。 -
是的，两个文件都可用，该文件中的条目也可用。
