Vivek, Thanks for sharing your knowledge with all of us. If you make an index unusable or invisible then that index will not be used in explain plan. But invisible index will be keep updated by oracle server on applicable statements like INSERT,UPDATE,DELETE. I have one question on this. Can you please explain the same by using trace on select statement?

Invisible index is maintained in the background for every single data change, so as soon as we make it visible it will be used in the query plans again( only if it adds value) I hope it helps, Saransh, please reach out to me if any clarification are required
