Definire un Database Services in a Single Instance Database
Sul db con SID SVIL1901 aggiungiamo il serive name ESTA
Vislaulizziamo i SERVICE NAME esistenti che rappresenta il nome interno del servizio registrato nel dizionario dati
SQL > SELECT name, network_name
FROM dba_services
ORDER BY 1;
FROM dba_services
ORDER BY 1;
SQL > SELECT name, network_name
FROM v$active_services
ORDER BY 1;
FROM v$active_services
ORDER BY 1;
Creare il servizio
SQL> BEGIN
DBMS_SERVICE.create_service(
service_name => 'ESTA',
network_name => 'ESTA'
);
END;
/
DBMS_SERVICE.create_service(
service_name => 'ESTA',
network_name => 'ESTA'
);
END;
/
Verifica che il serivizio è stato creato.
SQL> SELECT name, network_name
FROM dba_services
ORDER BY 1;
FROM dba_services
ORDER BY 1;
Ora avviare il servizio di Network
BEGIN
DBMS_SERVICE.start_service(
service_name => 'ESTA'
);
END;
/
DBMS_SERVICE.start_service(
service_name => 'ESTA'
);
END;
/
Verifica che compare la riga di ESTA
SELECT name, network_name
FROM v$active_services
ORDER BY 1;
FROM v$active_services
ORDER BY 1;
Se si vede lo sato del listener compare il servizio nuovo
