Well, sort of.
Berkeley databases are fully portable. Berkeley log files are portable
between machines with the same byte order. Only shared region files are
extremely non-portable. (This info comes from the Berkeley DB reference
manual, section "Database environment introduction")
What this means is, if you shut down all processes accessing the repository,
and call the Berkeley DB function DB_ENV->remove() to remove the __db.00?
region files, you can then begin using the repository on another OS. If it
is inconvenient to write some code to call DB_ENV->remove(), then running
the db_recover command line utility might be suitable, as it removes the
environment as part of running recovery. Even simply "rm"-ing the region
files seems to work fine.
Max.
