Hello,
I'm starting to analyze application queries with the Tuning Advisor and my manager wants to know if the recommendations returned are applicable across servers, instances, and databases of different sizes?
Meaning, if I analyze a query on my development workstation against a copy of our live database running on a local SQL instance, would the results returned be equally applicable to the database running on our production server? Likewise, would the results be applicable to a different size dataset located on a different SQL instance at one of our customer's locations?
We're trying to figure out if the tuning advisor is providing recommendations that would be universally applicable, regardless of where the database and application is running.
I've done a few tests against two different servers/instances, and the index recommendations seem to be consistent, but the statistics being recommended are close but not identical, even though the data is identical across the servers.
Any feedback would be helpful.
Thanks!
Bill
