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

You should only take on the extra administrative work of distributing the primary filegroupacross file on multiple disks if you have confirmed that disk I/O is a bottleneck for your system.The monitoring techniques discussed later in this paper can help you make this determination.For high-end systems and workloads, additional tuning and optimization techniques areavailable; refer to this guide (Analyzing I/O Characteristics and Sizing Storage Systems for SQLServer Database Applications) for more information.Use Data Compression (Enterprise Edition Only)SQL Server 2008 Enterprise edition includes the ability to natively compress its data pages ondisk. This saves space on the disk, and because it reduces the amount of disk I/O executed for agiven amount of data, data compression also improves performance. When data compression isenabled, data pages are also compressed in the buffer pool (i.e., RAM). This provides theadditional benefit of increasing the effective amount of application data that can be accessedfrom the data cache rather than accessed from the disk.Adjust SQL Server 2008 and Database SettingsThe following sections describe best practices for database settings.Verifying Database CollationWhen the ENOVIA database is created, it assumes the server collation (set during SQL Server2008 installation) unless otherwise specified. It is good practice to verify that the collation forthe database is the one the ENOVIA software expects. As shown in Figure 10, this can be verifiedin the Database Properties dialog box in SSMS. The collation displayed in this dialog box shouldbe Windows collation.Figure 10: Verify the Windows collation for ENOVIASet Automatic Statistic Updates, Auto Shrink, and Other OptionsSQL Server 2008 uses internal statistics about the data stored in tables to decide which indexes,if any, to use for most efficiently executing a query. As table data changes over time, thesestatistics need to be kept current. Each SQL Server database has the option for these statistics to28
