Database locking
All node and card properties are stored in a single MAT database. When you
open Node or Card Properties, the data for a given node (including card
properties) is then locked. If a second user tries to access a property sheet in
the same node at the same time as you, the second user is given the option of
overriding the lock. If the second user decides to override the lock and you
have made changes and then clicked “OK” or “Apply”, you are prov ided with
a message that says that their changes have been lost (see the second dialog
box in Figure46 on page 249). This message only appears if changes have
been made. If you try to open a property sheet in the node after rebooting the
PC, the first dialog box in Figure46 appears. In this example, a property sheet
was open when the MAT PC crashed.
