Memory Allocation

  • Hi All,

    SQL Server 2005

    From the perfmon, I can see that sql server is using 16GB of memory <perfmon, total server memory>.

    From the below URLs, I have managed to find out the memory used by data (buffer) and query plans (cache).

    Buffer:8.2GB

    Cache: 1.5G

    The above adds up to near 10GB. May i know what is utilizing the remaining 6GB? Anyway to find out?

    Appreciate your help.

    thanks

  • You can run DBCC memorystatus() command. this command provides a snapshot of the current memory status of SQl server.the memory manger section shows overall memory comsumption by SQl server.

  • Hi,

    DBCC execution completed. If DBCC printed error messages, contact your system administrator.

  • Hi Guys,

    I still have difficulty interpreting the output after reading up the dbcc memory status relevant documents. Can anyone help me with this? Appreciate your time on this.

    dbcc memory status output attached.

    thanks!

    My question:

    From the perfmon, I can see that sql server is using 16GB of memory <perfmon, total server memory>.

    From the below URLs, I have managed to find out the memory used by data (buffer) and query plans (cache).

    Buffer:8.2GB

    Cache: 1.5G

    The above adds up to near 10GB. May i know what is utilizing the remaining 6GB? Anyway to find out?

    http://www.sqlteam.com/article/what-data-is-in-sql-server-memory

    http://www.sqlteam.com/article/what-query-plans-are-in-sql-server-memory

  • 1) why do you want to know the various internal memory consumption? There is almost nothing you can do about it, and the knowledge is VERY unlikely to help you with any issue you might be having on the machine.

    2) If you REALLY want to know, buy one of the SQL Server Internals books. Probably your best resource.

    3) If you are having a particular issue you are trying to troubleshoot, please post that and see if we can help you. The odds of it being a memory issue (Other than not having ENOUGH of it) is very slim.

  • Hi Kevin,

    Appreciate response on this.

    You may ignore what I have posted above.

    The actual problem here i'm facing here is with an instance with multiple databases.

    From the total server memory (perfmon), i can see that sql server is utilizating alot of memory <making the memory utilization very high).

    I also understand that sql server will use as much memory it needed to cache the data and the plan.

    I'm tasked to identify the most memory utilized database so as to see if we can migrate it out to another very lowly utilized database server.

    I executed this statement:

    SELECT LEFT(CASE database_id

    WHEN 32767 THEN 'ResourceDb'

    ELSE db_name(database_id)

    END, 20) AS Database_Name,

    count(*)AS Buffered_Page_Count,

    count(*) * 8192 / (1024 * 1024) as Buffer_Pool_MB

    FROM sys.dm_os_buffer_descriptors

    GROUP BY db_name(database_id) ,database_id

    ORDER BY Buffered_Page_Count DESC

    However the total alot lesser than the total server memory. As such, I'm pondering where did the rest of the memory goes.

    I tried adding the 4 perfmon counter together as well, but still very much lesser than the total server memory.

    sqlserver:buffermanager:databasepages

    sqlserver:plan cache:cachepages

    sqlserver:memorymanager:connectionmemory

    sqlserver:memorymanager:sqlcachememory

    Would like to understand more on this so that i can better provide advise to my management.

    thanks !

  • SQL will use as much memory as you allow it to use. If you feel that an instance is using too much, lower it's memory limit.

  • Hi Gila,

    thanks for ur response. Yes agreed.

    But basically i wish to find out which of the db in the instance is utilizing the most memory. Anyway to do it?

    thanks

  • SQL doesn't segregate memory per database (except in terms of the data cache). You can check which DB uses up the majority of the data cache, you might be able to get a rough idea of the databases that the various plans in the plan cache belong to, providing that they're object plans not ad-hoc SQL. Other than that though, not so much.

    In addition to the data and plan cache, there are other caches, there's workspace memory, there's thread stacks and a whole lot of other stuff.

  • Note that which database is taking up buffer pool space can change drastically from minute to minute. I can run one big report-style query and flush just about everything but that data out of the buffer pool.

    There is MUCH more to getting good performance from a database than finding out what is using lots of RAM. You could very well wind up putting one of your databases on a different underutilized server and have it's performance be MUCH worse depending on the config, power and especially IO underpinnings of the new box.

    I would recommend you get a quick performance review by a professional to assist you in making good decisions here. He/she can likely find LOTS of issues to remediate. 🙂
