The internal Postgres database is embedded in the VMware Identity Manager appliance and is configured and ready to use by default.

You can configure the internal PostgreSQL database for high availability if your deployment leverages vRealize Suite Lifecycle Manager. See the vRealize Suite Lifecycle Manager Installation, Upgrade, and Management guide.

When VMware Identity Manager is installed and powered on, during the initialization process, a random password for the internal database user is generated. This password is unique to each deployment and can be found in the file /usr/local/horizon/conf/db.pwd.
