other service. The connect descriptor received by the listener specified a SIDfor an
instance (usually a database instance) that either has not yet dynamically
registered with the listener or has not been statically configured for thelistener.
This may be a temporary condition such as after the listener has started, butbefore
the database instance has registered with the listener. Action:
- Wait a moment andtry to connect a second time.
- Check which instances are currently known by the listener by executing:lsnrctl
services <listener name> 12-2 OracleDatabase Error Messages
- Check that the SID parameter in the connectdescriptor specifies an instance
known by the listener.
- Check for an event in the listener.log file.
