NGT Check offers the following benefits.
Minimal processing requirements
NGT Check does not need to sort table rows in order to check indexes. The product does not require sort work files that invoke I/O operations.
NGT Check runs on the actual objects, not copies of them. The table space and all of its indexes remain in read/write (RW) mode during the check process.
The time that NGT Check requires to check all indexes on a table space is nearly identical to the time that other products need in order to check just one index, so the NGT Check syntax is simplified always to check all indexes in a table.
