Set up VMware Identity Manager with an external database to store and organize server data. If you cannot use an external database, you can use the internal vPostgres database that is embedded in the appliance.

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 an external Microsoft SQL database server, Oracle database server, or an external vPostgres database server to set up a high availability external database environment. See Connecting to the Database.

The embedded vPostgres database configuration can be used for small deployments. The internal database does not require any additional configuration outside VMware Identity Manager, but it is recommended that you configure your internal database for high availability. See KB 2094258.
