Each VOB database contains a VOB object that represents the VOB
itself. If a VOB is replicated, it also has a replica object, which is created
by the mkreplica command.
The VOB object provides a handle for certain operations. For example:
- Listing event records of operations that affect the entire VOB (see the lshistory reference
page). This includes creation and deletion of type objects, removal of elements,
and so on.
- Placing a lock on the entire VOB (see the lock reference
page).
