how to find the piece of code that made an index unusable in oracle?
Hi All,
First of all, I appreciate your time.
I have a question. Just suppose we have a database which has many procedures and packages working on one table. there are some indexes on the table. they become unusable frequently. How to find the exact script which made the indexes unusable.
I have checked the alert log, could not find which statement made the indexes unusable.
I would be thankful if you could help me out in this regard.
BR,
Donald
