1. Configurare un database in standby per il recupero da errori irreversibili
  2. Esempio di file DG_properties.ini

File DG_properties.ini di esempio

Di seguito sono riportati alcuni esempi di file DG_properties.ini per diversi ambienti di database primario e in standby.

Esempio 1: sistema DB Oracle RAC OCI con sistema DB Oracle RAC OCI

Di seguito è riportato un esempio di file DG_properties.ini per la configurazione di Oracle Data Guard tra due sistemi di database Oracle Real Application Clusters (Oracle RAC) in Oracle Cloud Infrastructure (OCI), un sistema DB OCI primario e un sistema DB OCI in standby.La versione di questo esempio è 21c. Il file DG_properies.ini è lo stesso nel database primario e in standby. I commenti vengono troncati per la leggibilità.

Esempio 2: Oracle RAC on premise con sistema DB OCI Oracle RAC

Di seguito è riportato un esempio di file DG_properties.ini per la configurazione di Oracle Data Guard in un ambiente ibrido: tra un file Oracle Real Application Clusters (Oracle RAC) primario in locale e un sistema DB OCI in standby Oracle RAC, versione 19c.In questo caso, ci sono alcune differenze nelle proprietà generali. Poiché l'utente del sistema operativo della griglia è diverso tra il database primario e quello in standby, i file DG_properies.ini sono un po' diversi nei sistemi primario e in standby.
