Changing from bitmap indexes to Btree
807285Jan 25 2012 — edited Jan 25 2012Hi all,
oracle 11.2.0.1.0
I am working on a requirement to change bitmap indexes to b tree indexes. The bitmap indexes were created about 3-5 years ago. They were periodically analyzed. Since the data , unique data to be precise is increasing , we have resorted to change to btree indexes.
Can any one tell how should i start and the parameters i need to keep in mind while jusdging the enhanced performance. Also, I have read about clustering factor to as near to number of rows possible ... Please provide some direction into this...
Regards
