Find Number of Pages Each Database has in BufferPool

This query shows how many pages each database has in the buffer Pool. This will show you the breakdown of memory allocation for each database.
[cc lang=”sql”]
COUNT(page_id)as number_pages
FROM sys.dm_os_buffer_descriptors
WHERE database_id !=32767
GROUP BY database_id
ORDER BY database_id

Worked great, but when tried to use on servers with AWE enabled i got this error:
“Msg 208, Level 16, State 1, Line 1
Invalid object name ‘sys.dm_os_buffer_descriptors'”.

Is there an way to get this information on AWE enabled servers?

Hi Rafael, that’s interesting.. Unfortunately I haven’t run into that.. maybe someone else will know.
