any one has the idea ?? broker has the mapping , however memory_pools does not

Yesterday we have covered sys.dm_os_memory_objects. We will proceed further with more memory related DMVs. Today I will talk about sys.dm_os_memory_pools. Memory in SQL Server is designed on pool framework. Pool framework is similar to cache framework.
The memory clerks are internally memory pools. Pools are used in places where clerks are used. There are certain pools which are commonly used by multiple components. They are used to cache homogeneous and stateless types of data. Sys.dm_os_memory_pools provides a row each for each memory pool.
Sys.dm_os_memory_pools can be queried directly. The use case would be to determine if you have any problems with bad caching of memory. The important columns to notice are max_free_entries_count, free_entries_count and removed_in_all_rounds_count.
Max_free_entries_count – The max limit of free entries allowed in a pool
Free_entries_count – Current free entries in the pool
Removed_in_all_rounds_count – Number of entries removed since SQL Server started from the pool
The problems with memory caching can be identified by high number in removed_in_all_rounds_count and consistent low number in free_entries_count. As I mentioned before, sys.dm_os_memory_pools is more independent DMV.
SELECT type,
name,
max_free_entries_count,
free_entries_count,
removed_in_all_rounds_count
FROM sys.dm_os_memory_pools
ORDER BY removed_in_all_rounds_count DESC
sys.dm_os_memory_pools
In the above output we see OBJECTSTORE_LOCK_MANAGER is on top of list with more entries removed. But it would not concern me as I will be more interested if the free entries count is closer to 0. If I have problems with this cache I may receive an error like belowso there are only
sys.dm_os_memory_pools and dm_os_memory_brokers has pool_id
and clerks and objects don't have pool_id ....
So I am still confused how they link up ?

Instead of copy someone else article, why not simply add the link to the source article?
I checked some of your response from the list of activities in your profile and it seems like you simply google for content and steal it from others. Am I wrong?!? Can you confirm that all the users who wrote the content which you published gave you permission to use their content ?!?

Should I continue to check all the rest of your responses?!?
Do you understand the meaning of Plagiarism ?!?
Do you think that the virtual points in the forum are so important that you should do such actions?!?
If I am mistaken then please explain this ASAP!
