title: DMV in SQL 2008 to replace dm_os_exec_requests
body: <p>I've been going through an old SQL 2005 performance tuning document and it talks about the dynamic management view <code>sys.dm_os_exec_requests</code>. It looks like that view is no longer available in SQL 2008.</p>
  
  <p>Is there a direct replacement? Is there a standard way of selecting the same data from another DMV or group of DMVs?</p>
  
  <p>Thanks!</p>
