I suspect your Windows version (or Firebird version running there) is 32-bit, correct? > These are the versions on Firebird I tried on Ubuntu: > > - Firebird/linux AMD64 (access method), version "LI-V2.5.1.26351 > Firebird 2.5" > - Firebird/linux AMD64 (access method), version "LI-V2.1.7.18553 > Firebird 2.1" > - Firebird/linux AMD64 (access method), version "LI-V2.1.4.18393 > Firebird 2.1" > - Firebird TCP/IP server version LI-V1.5.4.4910 Firebird 1.5 > > All versions of Firebird fails to open the database with isql-fb with > the following message: > > SQL> connect "/home/user/a.fdb" user '*******' password '**********'; > > Statement failed, SQLSTATE = HY000 > file /home/user/a.fdb is not a valid database This error is raised when the database is not understandable to the engine. Prior to ODS 11, databases were not binary compatible between 32-bit and 64-bit architectures. You cannot just copy a ODS 10.1 database to a host with different bitness and use it there. Backup/restore is required instead. Dmitry
