One of our new sql 2005 SP3 4053 pre-prod server has trace flag 253 setup by the app team, their doc just says its to "prevent adhoc query plans to stay in cache", Internet or BOL search for this trace flag doesn't give much info.
Has anyone worked with this before or has info?
Also, Is there a place where all trace flags are mentioned with their uses, BOL only has a few listed?

Thanks for replying!

Unless this is something that PSS suggested be enabled for a specific issue, I would turn it off.


As a proof of concept, you may want to turn it off in dev - test - turn it back on and test again. Compare the results.
