完整的错误信息如下：

java.sql.SQLException: Listener refused the connection with the following error:ORA-12505, TNS:listener does not currently know of SID given in connect descriptorThe Connection descriptor used by the client was:192.168.149.128:1521:orcl at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:261) at oracle.jdbc.driver.T4CConnection.logon(T4CConnection.java:387) at oracle.jdbc.driver.PhysicalConnection.<init>(PhysicalConnection.java:414) at oracle.jdbc.driver.T4CConnection.<init>(T4CConnection.java:165) at oracle.jdbc.driver.T4CDriverExtension.getConnection(T4CDriverExtension.java:35) at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:801) at oracle.eclipse.tools.database.connectivity.db.OracleJDBCConnection.createConn(OracleJDBCConnection.java:199) at oracle.eclipse.tools.database.connectivity.db.OracleJDBCConnection.createConnection(OracleJDBCConnection.java:149) at org.eclipse.datatools.connectivity.DriverConnectionBase.internalCreateConnection(DriverConnectionBase.java:104) at org.eclipse.datatools.connectivity.DriverConnectionBase.open(DriverConnectionBase.java:53) at org.eclipse.datatools.connectivity.drivers.jdbc.JDBCConnection.open(JDBCConnection.java:72) at oracle.eclipse.tools.database.connectivity.db.OracleJDBCConnectionFactory.createConnection(OracleJDBCConnectionFactory.java:42) at org.eclipse.datatools.connectivity.internal.ConnectionFactoryProvider.createConnection(ConnectionFactoryProvider.java:83) at org.eclipse.datatools.connectivity.internal.ConnectionProfile.createConnection(ConnectionProfile.java:355) at org.eclipse.datatools.connectivity.ui.PingJob.createTestConnection(PingJob.java:76) at org.eclipse.datatools.connectivity.ui.PingJob.run(PingJob.java:59) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

解决方法：

打开Oracle的 listener.ora 文件：

（oracle/oracle/product/10.2.0/db_1/network/admin/listener.ora）

修改前：

# listener.ora Network Configuration File: /app/oracle/oracle/product/10.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /app/oracle/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
    )
)

LISTENER =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = suse10.site)(PORT = 1521))
    )
)

------------------------------------------------------------------------------------------------------------------------------

修改后：

# listener.ora Network Configuration File: /app/oracle/oracle/product/10.2.0/db_1/network/admin/listener.ora# Generated by Oracle configuration tools.LISTENER =  (DESCRIPTION_LIST =    (DESCRIPTION =      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))      (ADDRESS = (PROTOCOL = TCP)(HOST = suse10.site)(PORT = 1521))    )  )

---------------------11g版本SID_LIST_LISTENER =  (SID_LIST =    (SID_DESC =      (SID_NAME = PLSExtProc)      (ORACLE_HOME = /app/oracle/oracle/product/10.2.0/db_1)      (PROGRAM = extproc)    )    (SID_DESC =
      (GLOBAL_DBNAME = ORCL) 
      (ORACLE_HOME = /app/oracle/oracle/product/10.2.0/db_1)
      (SID_NAME = ORCL)
    )  )

-------------------------12c版本

SID_LIST_LISTENER=(SID_LIST=    (SID_DESC=      (GLOBAL_DBNAME=nextoss)      (SID_NAME=nextoss)    ))

上面的红色文字是增加的内容。 (ORCL -- 是你的SID 数据库名)

重启Oracle的监听器。

问题解决。
