Management of Global Partitioned Indexes

Global partitioned indexes are harder to manage than local indexes because of the following:

When the data in an underlying table partition is moved or removed (SPLIT, MOVE, DROP, or TRUNCATE), all partitions of a global index are affected. Consequently global indexes do not support partition independence.
When an underlying table partition or subpartition is recovered to a point in time, all corresponding entries in a global index must be recovered to the same point in time. Because these entries may be scattered across all partitions or subpartitions of the index, mixed with entries for other partitions or subpartitions that are not being recovered, there is no way to accomplish this except by re-creating the entire global index.
