Now that you know how to manage the partitions, start working with their indexes:
- Rebuilding Global Index Partitions
- Rebuild each partition by issuing the
ALTER
INDEX
...REBUILD
PARTITION
statement (you can run the rebuilds concurrently). - Drop the entire global index and re-create it. This method is more efficient because the table is scanned only one time.
- Rebuild each partition by issuing the
- Rebuilding Local Index Partitions
ALTER
INDEX
...REBUILD
PARTITION
/SUBPARTITION
ALTER
TABLE
...MODIFY
PARTITION
/SUBPARTITION
...REBUILD
UNUSABLE
LOCAL
INDEXES
- When managing the partitions, check if you might use UPDATE GLOBAL INDEXES
Path to Documentation:
Database SQL Language Reference -> ALTER INDEX
VLDB and Partitioning Guide -> 4 Partition Administration -> Maintaining Partitions (Rebuilding Index Partitions) - (Good for copy paste examples during the exam)
