ORA-12527: TNS:listener: all instances are in restricted mode or blocking new

ORA-12527
ORA-12527: TNS:listener: all instances are in restricted mode or blocking new
connections
Cause: All appropriate database instances supporting the service requested by the
client reported that they either were in restricted mode or were blocking the new
connections. The Listener does not allow connections to such instances. This
condition may be temporary, such as at instance startup.
Action: Attempt the connection again. If error persists, then contact the database
administrator to check the status of the instances.
