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:

我遇到这个问题是因为我在任务管理器中杀死了任务到“Oracle”任务。要修复它，你需要打开cmd ->类型:服务。>找到服务“OracleServiceXE”->右键单击:启动。

我只是错误地创建了数据库链接。

对我来说，简单的解决方法是简单地将“SID”更改为SERVICE_NAME

CREATE DATABASE LINK my_db_link
CONNECT TO myUser IDENTIFIED BY myPassword
USING
'
(
    DESCRIPTION=
    (
        ADDRESS=
        (PROTOCOL=TCP)
        (HOST=host-name-heren)
        (PORT=1521)
    )
    (CONNECT_DATA=(SID=theNameOfTheDatabase))
)';
