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。

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.

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

当我试图使用SQL开发器连接到oracle DB时，我得到了这个错误ORA-12505, TNS:侦听器目前不知道连接描述符中给定的SID。

使用的JDBC字符串是JDBC:oracle:thin:@myserver:1521/XE，显然是正确的，两个强制的oracle服务OracleServiceXE, OracleXETNSListener已经启动并运行。

我解决这个问题的方法(在Windows 10中)

 1. Open run command.
 2. Type services.msc 
 3. Find services with name OracleServiceXE and OracleXETNSListener in the list.
 4. Restart OracleServiceXE service first. After completing the restart try restarting OracleXETNSListener service.
