OCI-12526

TNS:listener: all appropriate instances are in restricted mode

Cause

Database instances supporting the service requested by the client were in restricted mode. The Listener does not allow connections to instances in restricted mode. This condition may be temporary, such as during periods when database administration is performed.


Action

Attempt the connection again. If error persists, then contact the database administrator to change the mode of the instance, if appropriate.
