Best Practices for Running Dassault Systèmes ENOVIA ... - Microsoft

Configure RAM on 32-bit Servers (V6R2011 and Earlier Only)The use of 32-bit database servers is increasingly rare. Dassault Systèmes strongly recommendsthat you run your ENOVIA database on a 64-bit server running a 64-bit Windows operatingsystem with a 64-bit edition of SQL Server 2008. The key advantage of a 64-bit server fordatabase workloads is the ability to efficiently use much larger amounts of RAM.If you are using a 32-bit server to host the ENOVIA database, Dassault Systèmes recommendsconfiguring SQL Server 2008 to use as much RAM as possible. By default, a 32-bit process (i.e.,an x86 install of SQL Server 2008) can use at most 2 GB of system RAM. If the database serverhas 4 GB or more of RAM, SQL Server 2008 should be configured to use Address WindowingExtensions (AWE) memory. A simplified description of the procedure for enabling AWE memoryfor SQL Server 2008 is as follows:1. Add the /PAE switch to the Windows boot.ini file. An example of this procedure can befound at http://support.microsoft.com/kb/283037. Note that a server restart is requiredfor this change to take effect.2. Grant the Lock pages in memory permission to the SQL Server service account. Thispermission is required for SQL Server 2008 to use AWE memory. Refer to How To:Enable the Lock Pages in Memory Option if necessary.3. Execute the following commands in a query window in SSMS:exec sp_configure 'show advanced options', 1RECONFIGUREGOexec sp_configure 'awe enabled', 1RECONFIGUREGOexec sp_configure 'min server memory', 8192RECONFIGUREGOexec sp_configure 'max server memory', 12288RECONFIGUREGOSubstitute appropriate values (in MB) for the min and max server memory settings. Theexample uses values that might be appropriate for a server with 16 GB of RAM.4. Restart SQL Server 2008.24
