Question

I’ve been going through an old SQL 2005 performance tuning document and it talks about the dynamic management view sys.dm_os_exec_requests. It looks like that view is no longer available in SQL 2008.

Is there a direct replacement? Is there a standard way of selecting the same data from another DMV or group of DMVs?

Thanks!

Answer 1

That DMV never existed, I just tried it on 2005 also

there is sys.dm_exec_requests and that returns the data in the slide attached as a comment

maybe it was a typo

sys.dm_os_* are the following dmvs
