DBT-19644
Standby database service name 'string' present in the alias entry of the specified tnsnames.ora file or in the blob file for the database 'string' is not valid. The expected service name is 'string'.
Cause
The standby database service name for the database '%s' should adhere to the default service name format <db_unique_name>[.<db_domain>]. The failure may be due to specifying an incorrect standby database service name/domain name when executing the prepareForStandby command on the primary database.
Action
Rerun the prepareForStandby command on the primary database with the correct standby database service name/domain name.
