When to use the update global indexes clause?
However, the UPDATE GLOBAL INDEXES clause may be used with DROP PARTITION, TRUNCATE PARTITION, and EXCHANGE PARTITION operations to keep the global indexes on index-organized tables usable. For the remaining operations in the above list, global indexes on index-organized tables remain usable.
Why does the global index become unusable?
The global index has become unusable because a portion of the rows that had entries in the index have been moved as part of the partition split operation. The local index has also become unusable but only for those partitions that were impacted by the split.
Can a global index be rebuilt in nologging mode?
In contrast, if you rebuild an entire global index, you can do so in NOLOGGING mode. Rebuilding the entire index manually creates a more efficient index, because it is more compact with better space utilization. The UPDATE INDEXES clause is not supported for index-organized tables.
When to use global index or local index in partition maintenance?
And as most people are aware, the latter is the default when you perform a partition maintenance operation on a table that re-locates rows. For example, we’ll create a simple partitioned table, add both a local and a global index, split one of the partitions, and then see what the impact on those indexes is.
