Hello Olaf,

thank you for your reply.

I found out that the Database was changed automatically in to single_user modus directly after the installation of DB patches.

So it is like after installation of a new patch, every service got shutted down and the SQL Server restart in a single user modus with the message "SQL Server wurde im Einzelbenutzermodus gestartet. Diese Meldung dient nur zu Informationszwecken. Es ist keine Benutzeraktion erforderlich. (SQL Server started in single user mode. This message is for informational purposes only. No user action is required.)"

When installing SQL patches, SQL Server may start in SINGLE user mode to apply patches, but it should not remain in SINGLE user mode after the patches are fully applied.

Thank you for the information. I noticed sometimes it remains but sometimes not.
But the main thing is that I know where the problem is.
Thank you 🙂
