Snapshot

You can take a data ‘snapshot’ (save the whole content of the map) at any time. One Viz Engine can save the whole content of the map by calling the map’s SaveToDb procedure, and another client can read it by calling LoadFromDb.

The downside of this approach is that these functions block the renderer and can cause poor performance of the Graphic Hub database, if the map is stored repeatedly.

IMPORTANT! The resulting SHM map objects are replicated as well. So saving the map each field or every minute can result in serious problems for the Graphic Hub database (replication failing, etc.).

Note: For more information see the script function documentation. Go to, Start -> All Programs -> vizrt -> Viz 3.x -> Documentation -> Script Documentation -> Data Types and procedures -> Shared Memory, or <viz install folder> -> ScriptDoc -> DataTypeSharedMemory.
