Q:Invisible index and/or creating a new index
Hello,
we have a SQL Statement (Payroll job) that runs too long for our liking and after running SQL Tuning Advisor on this perticular SQL Statement I got recommended to crate an index to speed up the process. Is this a supported thing to do as the SQL Statement is a Oracle developed statement and not a customization from our side? Also, is it supported to make indexes invisible for the same query as we are running on an Exadata and currently there is no offloading to the storage cells on this SQL Statement?
Thanks
Andy
