| Add a counter in performance monitor for SQL:Buffer manager and you can analyse how much memory is being used by SQL server. |

| Sql will use all available memory on the server by default, it's normal. |

| You shouldn't restrict the memory unless there are other server processes on the box which is not recommended anyway. But SQL using all of the memory is completely normal, it's what makes SQL so fast! And it's isn't what is causing the computer to be unusable. Can you explain more?What else do you have running on this server?Tara KizerMicrosoft MVP for Windows Server System - SQL Serverhttp://weblogs.sqlteam.com/tarad/ |

| Set max memory with sp_configure if you really want to do that. |

| As mentioned a few times already, this is normal. Why do you think this is a problem? Please answer the following questions so that we can help you further:What else do you have running on this server? You don't need to adjust the memory setting unless this is a cluster or you have other processes running on it. How big is the database? How much total memory do you have on the server? What size is the page file set to?Tara KizerMicrosoft MVP for Windows Server System - SQL Serverhttp://weblogs.sqlteam.com/tarad/ |

| What else do you have running on this server? You don't need to adjust the memory setting unless this is a cluster or you have other processes running on it. -- a lot it's an office serverHow big is the database? 400 mb i thinkHow much total memory do you have on the server? 4.00 gbWhat size is the page file set to? How do I check this? |

| A 400MB database is small. Use sp_configure to change the max memory for the instance to 512MB (approximate guess on what you need).Tara KizerMicrosoft MVP for Windows Server System - SQL Serverhttp://weblogs.sqlteam.com/tarad/ |

400 mb for an office server database? if this is a shared network directory or something, that could certainly cause some issues as it may be competing with a lot of other file operations. Something in the whole setup of this sounds way off...a large office would have server admins and DBA's for sure that should be able to handle this..
Poor planning on your part does not constitute an emergency on my part. |

| I think you need to get a DBA to analyse: 1)major memory usage withing SQL Server. 2)Confirm server configuration.For example , some changed setting is killing memory3)Analyse the design and relevant workloadIf all the above is OK , consider moving SQL Server to it's own dedicated box Jack Vamvas--------------------Search IT jobs from multiple sources- http://www.ITjobfeed.com |

| ok unfortunately no dba here.it's me the programmer and then the sysadmin who doesn't want to seem to touch sqlas far as Use sp_configure to change the max memory for the instance to 512MB (approximate guess on what you need).can i also configure the amount of virtual memory used? Is that possible? and how much of the cpu it can use? |
