Understanding the Mailbox Database Cache http://technet.microsoft.com/en-us/library/ee832793.aspx You can modify the default database cache size values by making changes to the msExchESEParamCacheSizeMax and msExchESEParamCacheSizeMin attributes in Active Directory. For additional details, see How to modify the Store Database maximum cache size in Exchange 2000 Server. Use 32KB pages for the cache sizing calculations.Sukh

Hi 1.Start ADSIEDIT.msc 2.Navigate to Configuration > Services > Microsoft Exchange > <Organization Name> > Administrative Groups > <Administrative Group> > Servers > <Server Name> > InformationStore 3.Right-click InformationStore, and edit msExchESEParamCacheSizeMax. Set it it to the number of pages to maximize the Database Cache to. Note that Exchange 2007 works with 8 KB pages and Exchange 2010 with 32 KB pages! 4.Restart the Microsoft Exchange Information Store service for the change to become effective. So, for instance, if you want to limit the Database Cache to 4 GB of an Exchange 2010 server, set msExchESEparamCacheSizeMax to 131072 (4 GB = 4.194.304 KB / 32 KB).

What if my Exchange server only have 2GB of memory? - How do I make it not to optimize all the memory?Stan

Recommene is 4GB min for MS Support. I wouldn't be messing around with DC Cache if you only have 2GB. I'd advise you to plan your deployment. http://technet.microsoft.com/en-us/library/dd346700.aspxSukh

This is test server, thus the specification is lower. I'm trying to reduce the utilization of memory since test server only have 2GB of RAM.Stan

Note that Exchange 2007 works with 8 KB pages and Exchange 2010 with 32 KB pages! 4.Restart the Microsoft Exchange Information Store service for the change to become effective. So, for instance, if you want to limit the Database Cache to 1 GB of an Exchange 2010 server, set msExchESEparamCacheSizeMax to 32768 (1 GB = 1048576 KB / 32 KB). for instance, if you want to limit the Database Cache to 1.5 GB of an Exchange 2010 server, set msExchESEparamCacheSizeMax to 49152 (1.5 GB = 1572864 KB / 32 KB). Your environment doesn't meet min requirement. Maybe it can't run smoothly.Terence Yu TechNet Community Support
