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

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: services lamp;lt;lamp;nbsp;listener namelamp;gt; known by the listener.
