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.
