[Newbies] Omnibase (OSProcess undefined)

[ernst]

Have loaded Omnibase from OmniBase-DG.6.mcz (tried also SqueakMap)
DoIt:   db := OmniBase createOn: 'MyDB'
and get a walkback because OSProcess is undefined (see below).
Is OSProcess a class or some kind of global variable?
How to fix it?

Thanks

ensureAccessMode: accessMode forFileStream: aFileStream

	needsWriteAccess := (accessMode = self accessModeReadOnly) not.
	(OSProcess accessor
		isLockableFile: aFileStream
		from: self shareModeFlagLocation
		to: self shareModeFlagLocation
		exclusive: needsWriteAccess)
			ifFalse: [ODBLockingConflict signal].
