Set up VMware Identity Manager with an external database to store and organize server data. An internal PostgreSQL database is embedded in the appliance but it is not recommended for use with production deployments.
To use an external database, your database administrator must prepare an empty external database and schema before connecting to the external database in the Setup wizard. Licensed users can use a Microsoft SQL database server or Oracle database server to set up a high availability external database environment. See Connecting to the Database.
