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.
