Contained in the left box are all options for generating Node Cache. The user must specify the following:

1. Generate cache between nodes on the same floor only: (Y/N). Default is Yes.
2. Select the floor to generate cache for: (Default: All Floors).
3. Only generate cache for combinations of nodes that are directly connected to locations: (Y/N): Default is Yes.
4. Delete existing cache first (N/Y). Default is Yes.

Clicking on the Generate Node Cache button creates an entry in Scheduled Requests. The progress of the task can be monitored on the Monitor > Scheduled Request screen.

Contained in the right box are all options for generating Location Cache. The options that the user must specify are similar to those for Node Cache:

1. Generate cache between locations on the same floor only: (Y/N). Default is Yes.
2. Select the floor to generate cache for: (Default: All Floors).
3. Select the number of combinations, per location to cache: Default is 100. This generates cache between each location and it's closest 100 locations.
4. Delete existing cache first (N/Y). Default is Yes.

Clicking on the Generate Location Cache button creates an entry in Scheduled Requests. The progress of the task can be monitored on the Monitor > Scheduled Request screen.

Maintaining Node and Location Caches

Whether or not the two caches need to be recalculated depends on what was changed. Here are the different change scenarios and requirements:

1. Location is added to a pre-existing Segment: no change to either cache is required.

2. Location is added to a newly imported Segment: additional node cache may be required. It is not necessary to delete existing node cache, simply regenerate it for the affected floor and automatically create any node cache that is missing due to the recent import of Segments.
