Restore database and leave it in single user shutdown state

 Description  « Hide
Database recovery isn't always complete after backup restore. In some cases it needs some additional steps. To prevent users from accessing database during these steps, it would be good to have a gbak/services option to leave the database in single user maintenance mode after restore.

In some cases (for example, when index participating in FK fails to activate) this is already done. I.e. I agree that leaving DB in maintenance mode is good idea, the question is - after what errors this does not happen?

Without any error. A new option for the service: leave the database down even on success.

Why is a new option required?

When user can restore to a different filename/location to perform any additional steps, then rename the file when ready for production use.

You can restore database onto remote server. You cannot rename files on remote server using Firebird services.

A "single user maintenance mode" won't let others connect before you and leave you locked?

IIRC, only SYSDBA and database owner can connect to a database in this mode. Exactly because of this this mode is set for the database during restore process.
