有一台服务器上Oracle运行正常，另外一台Ora-12514错误。系统为HPUX11.23。 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.
