What will continue to function while a XenDesktop site database is offline?

Citrix Studio requires continuous database connectivity to read site topology and configuration data, making it non-functional when the database is offline.

Citrix Director depends on the site database for session monitoring, historical data, and Director-initiated actions, so it cannot operate without database access.

Anonymous connections are new connection requests that require the broker to query the database to enumerate resources and create sessions, which cannot occur while the database is offline.

Existing user connections to Desktop OS machines persist through a database outage because active session data is held in memory on the Virtual Delivery Agent and broker, not requiring continuous read/write access to the site database. XenDesktop is designed to protect active sessions from database-level failures, ensuring users already connected are not disconnected. New broker operations and management functions are suspended, but live sessions are unaffected.
