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。

RMAN-04006: error from auxiliary database: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
This error occurs when RMAN is unable to connect to the auxiliary database because the listener does not recognize the service requested in the connect descriptor. This can happen if the service name or SID specified in the RMAN connect string is incorrect or if the listener is not configured to recognize the requested service.
To resolve this issue, verify that the service name or SID specified in the RMAN connect string is correct and matches the service name or SID of the auxiliary database. Additionally, check that the listener is configured to recognize the requested service by checking the listener.ora file for the appropriate service entry. Finally, restart the listener to ensure that it is running and recognizes the requested service.
ORA-12514: TNS:listener does not currently know ofservice requested in connect descriptor
"ORA-12514: TNS:listener does not currently know of service requested in connect descriptor" 错误表示您在连接描述符中请求的服务当前无法被 TNS 监听器识别。这通常是由于服务名(SERVICE_NAME)在监听器上没有正确配置导致的。如果 TNS 监听器已成功启动并且已经识别到您请求的服务名,您可以通过查看已注册服务和正在监听的端口的信息来确认这一点。
如果您遇到了这个错误,您可以参考中介绍的图文解决教程进行处理。这个教程详细说明了如何解决连接Oracle数据库时报ORA-12541:TNS:无监听程序的问题,虽然错误信息不完全相同,但是其中一些步骤和解决方法也适用于您遇到的问题。
