Are all Berkeley DB features available for VxWorks?
All Berkeley DB features are available for VxWorks with the exception of the DB_TRUNCATE flag for DB->open. The underlying mechanism needed for that flag is not available consistently across different file systems for VxWorks. • Are there any constraints using particular filesystem drivers? There are constraints using the dosFs filesystems with Berkeley DB. Namely, you must configure your dosFs filesystem to support long filenames if you are using Berkeley DB logging in your application. The VxWorks’ dosFs 1.0 filesystem, by default, uses the old MS-DOS 8.3 file-naming constraints, restricting to 8 character filenames with a 3 character extension. If you have configured with VxWorks’ dosFs 2.0 you should be compatible with Windows FAT32 filesystems which supports long filenames. • Are there any dependencies on particular filesystem drivers? There is one dependency on specifics of filesystem drivers in the port of Berkeley DB to VxWorks. Berkeley DB synchronizes data using the FIOSYNC f
