The VOB object and replica objects

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).
