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.

In fact, I forget to start the service OracleServiceXXX (XXX stands for sid name). = =!

Chart doesn't display. When click "Redraw" get below error message:

An error occurred during execution of "connect". No connection could be made because the target machine actively refused it. [Socket:820]

resolve: Start "Oracle BI Java Host" service.
