Domain indexes (indexes created and maintained by user-defined indexing schemes)
are managed on partitioned database objects that store data using a system-managed
approach. Partition maintenance operations performed on the partitioned database
objects cause corresponding partition maintenance operations to be performed on
the domain indexes. Partition maintenance operations are performed on both the
database objects and the indexes by a system-supplied partition manager. Changes
in the partition maintenance operations or partitioning methods supplied by the
database management system do not affect user-supplied code which is provided by
the user-defined indexing scheme. User-supplied code is therefore partition operation-unaware.
