Is there a way to unlock a vision file on Unix/Linux when a lock is held by the OS even though there are no runtimes accessing the file.
First make sure there are no runtimes holding the file open. If there are, stopping them should solve the problem, but if not:
$ cp ORIG.DAT TEMP.DAT
$ mv ../ORIG.DAT
$ mv TEMP.DAT ORIG.DAT
$ vutil -rebuild ORIG.DAT
