Best Practice for SQL Profiles?
We just discovered that a particular query benefits greatly when we implement an SQL Profile that OEM's Tuning Advisor recommended. The before and after cost is 400,000 and 800. My question is how do others use SQL Profiles? We need to get this into production and my first thought was it should be promoted up from dev --> test --> UAT --> production. Is this the 'best practice' or should the tuning advisor be run directly against production referencing this particular SQL?
On a side note, we can't seem to successfully export and import the profile from dev to test. We followed a very good document:
