If the disaster recovery topology contains any databases related to Oracle Base Database Service, Oracle Exadata Database Service on Dedicated Infrastructure, Oracle Exadata Database Service on Exascale Infrastructure, Oracle Exadata Database Service on Cloud@Customer, use the steps in this topic to prepare the databases for Disaster Recovery (DR).

1. Configure a Data Guard group for the primary database.
2. Ensure that the Data Guard peer (standby database) is in the standby region that you intend to use for disaster recovery.
   Note
   
   Data Guard allows you to configure multiple standby database. However, Full Stack DR only supports one of these standby databases.
3. Create a vault in the primary and standby regions.
4. Create a secret in each of the primary and standby vaults.
5. Store the database sysdba password in the secrets created in the primary and standby regions.
   Note
   
   This secret containing the database password is required when creating a disaster recovery configuration for the database.
