ORA-12505: TNS:listener does not currently know of SID given in connect descriptor

Cause: The listener received a request to establish a connection to a database or other service. The connect descriptor received by the listener specified a SID for an instance (usually a database instance) that either has not yet dynamically registered with the listener or has not been statically configured for the listener. This may be a temporary condition such as after the listener has started, but before the database instance has registered with the listener.

Action:

- Wait a moment and try to connect a second time.

- Check which instances are currently known by the listener by executing: lsnrctl services <listener name>

- Check that the SID parameter in the connect descriptor specifies an instance known by the listener.

- Check for an event in the listener.log file.

ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

Cause: The listener received a request to establish a connection to a database or other service. The connect descriptor received by the listener specified a service name for a service (usually a database service) that either has not yet dynamically registered with the listener or has not been statically configured for the listener. This may be a temporary condition such as after the listener has started, but before the database instance has registered with the listener.

Action:

- Wait a moment and try to connect a second time.

- Check which services are currently known by the listener by executing: lsnrctl services <listener name>

- Check that the SERVICE_NAME parameter in the connect descriptor of the net service name used specifies a service known by the listener.

- If an easy connect naming connect identifier was used, check that the service name specified is a service known by the listener.

- Check for an event in the listener.log file.

나같은 경우는 서비스네임이나 SID를 잘못적어서 생긴 문제였다.

cmd 에서

lsnrctl services 를 입력하면

리스터의 상태가 출력된다.

여기서 DECATED의 상태가 READY인 SID를 이용하면 된다.
