As backing database we upgraded to the latest version of Firebird. You can find more about this upgrade at https://www.firebirdsql.org/file/documentation/release_notes/html/en/3_0/rnfb30-general.html#rnfb30-general-v305
Firebird.exe
Distribution for customers and build machines
WS_Firebird.exe
Distribution for SMS-Timing internal servers
SMS_Install.bat
If you copy both SMS_install and (WS_)Firebird.exe on the desktop, it will install firebird to c:\fast. If you put it inside any other folder, Firebird will be installed in that subfolder.
If you need to upgrade all webservers… just copy both files to the desktop of the server and run SMS_install.bat.
