Limit Exchange Database Cache


Wanneer Store.exe nogal veel geheugen neemt kan je dit limiteren

  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). If you want to limit the Database Cache to 2 GB of an Exchange 2007 server, set msExchESEparamCacheSizeMax to 262144 (2 GB = 2.097.152 KB / 8 KB).

To get Exchange 2010 SP1 to honor the configured msExchESEparamCacheSizeMax value, we need to configure msExchESEparamCacheSizeMin as well. The location is identical, so consult the initial post on how to perform this step; where it reads msExchESEparamCacheSizeMax, use msExchESEparamCacheSizeMin as well.

When we configure a value of 256 for msExchESEparamCacheSizeMin (8 MB) we get the following result after restarting the information store:
