Re: Bitmapped Indexes, Anyone?

To use bitmap indexes you need to install the parallel query option. This cannot be added to an existing install - you have to re-install the whole lot which can be a real pain if you are using 7.3.2.2/3 (because they are patch releases) so it's a case of install the base release (with PQO) then apply the patch.

It may seem like a lot of trouble but it's well worth the effort. Bitmap indexes open up a whole new area of design and functionality for MIS applications - and you'll benefit from parallel query as well!

Let me know how you get on using them.

Good luck.
