17. Configurethe MemoryforSQL Server IfyourPROSPricingSolutionSuite database(data+indexes)isoris expectedtobemuchlargerthanthe totalRAMonthedatabaseserver,PROS recommendsconfiguringtheminimum andmaximumservermemoryoptionsin SQLServer Physical RAM 8GB 16GB 24GB 32GB 48GB 64GB 96GB 128GB MinSQLServermemory 4,096MB 8,192MB 12,288MB 16,384MB 32,768MB 49,152MB 73,728MB 104,448MB MaxSQLServermemory 5,120MB(5GB) 12,288MB(12GB) 18,432MB(18GB) 25,600MB(25GB) 39,936MB(39GB) 56,320MB(55GB) 88,0640MB(86GB) 120,832MB(118GB)

18. UseData Compression (SQLServer EnterpriseOnly) Datacompressionprovidesspace savingsondisk Becausedatacompressionreduces theamountofdiskI/O,ittendsto improveperformance Datapagesarealsocompressedin thebufferpool,increasingthe effectiveamountofapplication datathatcanbeaccessedfromthe datacacheratherthandisk

20. MonitorIndex Fragmentation,and DefragmentWhen Necessary Fragmentationcanreducethespeedof dataaccessandresultinslower applicationperformance Totellwhichindexeshave fragmentationproblems,use sys.dm_db_physical_stats() Trackfragmentationwith avg_fragmentation_in_percent,and chooseacourseofaction Notes: –Reorganizinganindexdoesnotblock useraccesstotheindex –Rebuildingorre-creatingtheindexdoes preventuseraccesstotheindex oToavoidblocking,useALTERINDEX REBUILDwiththeONLINE=ONoption oOnlineindexrebuildrequiresSQLServer 2008Enterprise Fragmentation <5% 5%-30% >30% Recommendedaction Donothing Reorganizewith ALTERINDEXREORGANIZE Rebuildwith ALTERINDEXREBUILDWITH (ONLINE=ON) or CREATEINDEXwithDROP_EXISTING=ON

21. CheckDatabaseIntegrityRegularly UseDBCCCHECKDB Itisbesttoincludedatabaseintegritychecksinascheduled job Ifproblemsaredetected,restorefromthebackup,orusea repairoptiononDBCCCHECKDB

22. UsethePROS Auto-Generated IndexedViews PROSautomaticallycreatesthe indexedviewstooptimizequeriesof lookups Indexedviewsareautomatically createdbasedonpricingdimension levels

23. SettheMaximum Degreeof Parallelism (MDOP)to1 Thisvalueidentifiesthenumber ofthreadsusedtoexecutea parallelplan Changingthissettingreduces blocking,deadlocks,andlocks PROSsoftwareparallelizeswork intheapplicationtier

24. PROSScientificAnalytics performanceisoptimizedusing AnalysisServices AnalysisServiceswilloptimizePROS performancebasedonuserqueries UseAnalysis ServicesUsage- BasedOptimization

25. ConsiderCube Partitioningwith MoreThan20 MillionRecords CubepartitioningallowsAnalysis Servicestoleveragemultiplecores –Improvescubeprocessingtime –Improvesquerytime Microsoftgenerallyrecommendsthat partitionsdonothavemorethan20 millionrecords Increasethemaximumnumberof databaseconnectionswhenthenumber ofpartitionsisabove10 –Formoreinformation,seesection 6.10oftheAnalysisServices PerformanceTuningGuide

35. Bottleneck Analysis Bottleneck – A point or component of a process where throughput is the slowest. Understanding where time is spent Elapsed Time = Running + Waiting Key is the waiting - what type of wait(s)?

36. Disk I/O Bottleneck Analysis Monitor and identify I/O bottleneck Resource Monitor & Performance Monitor MDW DMV & Extended Events What is driving high I/O load? Inefficient query plan Too much data to read/write Slow I/O subsystem

37. Resource Monitor File level I/O throughput and disk response time
