Object IDs

Identity Manager generates globally unique identifiers (GUIDs) for objects by using the VMID class provided in the JDK software.

These GUID values exhibit a property that gets sorted by its string representations, based on the order in which the objects are created. For example, when you create new objects with Identity Manager, the newer objects have object IDs that are greater than the older objects. Consequently, when Identity Manager inserts new objects into the database, the index based on object IDs can encounter contention for the same block or blocks.
