SQL Server Memory usage

    What is the normal memory usage.

    I get warnings that my memory usage is high but when I check, my memory paging is low (0%) and buffer and proc cache hit look good.

    Thanks

    Where do the warnings come from?

    Can you also provide the actual message?

    Also, assuming you are on a physical (not virtual server) what is the Available Memory In Task Manager?

    I just get the generic warnings from Idera SQL Diagnostic Manager

    1. SQL Server instance sqlprod is currently using 92.00% of the server memory.

    2. SQL Server instance sqlprod - The operating system has 98.65% of memory in use.

    The box is a VM in the cloud.

    This is normal when you haven't set max memory for SQL Server. SQL Server will take all of the memory you allow it.

    It's risky to run with the default SQL Server max memory setting (unlimited). Please have a look at this article: http://www.sqlservercentral.com/blogs/glennberry/archive/2009/10/29/suggested-max-memory-settings-for-sql-server-2005_2F00_2008.aspx

    The following will set the max server memory to the value you specify in MB's

    exec sp_configure 'show advanced options', '1'

    reconfigure

    exec sp_configure 'max server memory (MB)', 'set this'

    reconfigure

    exec sp_configure 'show advanced options', '0'

    reconfigure
