The prerequisites that must be fulfilled when recovering a tenant database include:

The tenant database must be stopped before the recovery starts: Ensuring the database is not running is crucial to avoid conflicts and data corruption during the recovery process.

The logon credentials of the system database user must be available: This is necessary because recovery operations often require administrative privileges, and the system database user typically has the required level of access.

References=SAP HANA recovery procedures and prerequisites are thoroughly detailed in the SAP HANA administration guide, which stipulates the necessary conditions and user permissions for successful database recovery operations.
