9.2 CONFIGURING THE ON-DEMAND LEVEL FOR A MAP

The demand level of a map determines the level at which submaps will be persistent. All objects on a persistent submap are loaded into memory as long as the map remains open. A submap that is not persistent is transient. Objects on a transient submap are only loaded into memory when the transient submap is accessed. The demand level may be customized to affect the number of objects that are loaded into memory when a map is opened. When setting the demand level of a map, keep in mind that certain features of NNM, including third-party applications, may require an object to be persistent in order to function properly. For this reason, you may define a persistence filter to cause a submap containing any object that meets the filter criteria to be persistent. The persistence filter is applied in the same dialog box as defining the demand level, shown in Section 9.4, "Defining Filters"). The following steps allow you to configure the demand level of a map:
