Hi all,
we have a couple of huge tables and we have some performance problems while creating indexes. Here are some methods we already have tried, is there something else:
Here's the list of features we already know:
- Using NOLOGGING mode
- Using PARALLEL option => PARALLEL 4 (the server has 4 CPU's)
- Using NOSORT option => not applicable because the rows are not stored in the right order
- Creating an index first as unusable and then rebuilding it => this was tested after the QA cutover but the duration remained unchanged
- Increasing sort_area_size => has not yet been tested
Something else, any help will be appreciated...
