listener was not given the service_name in connect_data

这个错误提示是因为在连接数据库时没有给出正确的服务名(service_name)。服务名是Oracle数据库中的一个重要参数,用于标识数据库实例。在连接数据库时,需要指定正确的服务名才能成功连接数据库。建议检查连接字符串中的服务名是否正确或者是否存在。

ORA-12504: TNS:listener was not given the SERVICE_NAME in CONINECT_DATA
ORA-12504错误表示在连接数据库时,监听程序未能识别服务名(SERVICE_NAME)。这可能是因为您在连接数据库时使用的连接字符串未指定正确的服务名。
请尝试使用以下格式的连接字符串进行连接:
```
<username>/<password>@//<hostname>:<port>/<service_name>
```
其中,`<username>` 是您的数据库用户名,`<password>` 是您的数据库密码,`<hostname>` 是您的数据库主机名,`<port>` 是您的数据库端口号,`<service_name>` 是您的数据库服务名。
例如:
```
scott/tiger@//localhost:1521/orcl
```
如果仍然遇到问题,请确认您的监听程序是否正在运行,并且已经注册了正确的服务名。您可以通过以下命令检查监听程序是否正在运行:
```
lsnrctl status
```
如果监听程序未在运行,请使用以下命令启动:
```
lsnrctl start
```
如果以上方法都无法解决问题,请检查您的数据库是否已经正确配置了服务名。
listener does not currently know of service requested in connect descriptor
This error message typically appears when the Oracle database listener is unable to locate the service requested in the connect descriptor. This can happen for several reasons, including:
1. The service name specified in the connect descriptor is incorrect or misspelled.
2. The service is not registered with the listener and needs to be added.
3. The listener is not running or is not configured correctly.
To resolve this issue, you can try the following steps:
1. Check the connect descriptor to ensure that the service name is correct and spelled correctly.
2. Verify that the service is registered with the listener by running the lsnrctl services command.
3. If the service is not registered, add it using the lsnrctl add_service command.
4. Restart the listener and try connecting again.
If these steps do not resolve the issue, you may need to check the listener configuration files and network settings to ensure that they are correct. It may also be helpful to check the Oracle documentation or seek assistance from a database administrator or Oracle support.
