50Planning PhaseIncorporate Design ConsiderationsWhile migrating, you may want to utilize some of the advanced functions that areincorporated into SQL Server and Windows Server 2003. Some references may exist<strong>for</strong> Windows® 2000 but the in<strong>for</strong>mation also applies to Windows Server 2003. For morein<strong>for</strong>mation, refer to the following resources:● Designing <strong>for</strong> scalabilityhttp://msdn.microsoft.com/library/default.asp?url=/library/enus/architec/8_ar_sa2_8rnd.asp● Designing <strong>for</strong> availabilityhttp://www.microsoft.com/technet/prodtechnol/sql/2000/plan/ssmsam.mspx● Designing <strong>for</strong> reliabilityhttp://www.microsoft.com/mscorp/twc/reliability/default.mspx● Designing <strong>for</strong> per<strong>for</strong>mancehttp://www.microsoft.com/sql/evaluation/compare/benchmarks.asphttp://www.microsoft.com/technet/prodtechnol/sql/2000/maintain/ansvcspg.mspx● Designing <strong>for</strong> interoperabilityhttp://www.microsoft.com/technet/prodtechnol/sql/2000/deploy/sqlorcle.mspxHardware Design ConsiderationsIn addition to the advanced features available in SQL Server, there are many softwaretools available to assist in ensuring that the correct hardware is acquired. Some of thesetools are listed here:● Microsoft Datasizer Tool. This spreadsheet helps estimate table sizes.

These tools are available to assist in selecting Dellhardware <strong>for</strong> use with SQL Server. For more in<strong>for</strong>mation, refer tohttp://www1.us.dell.com/content/topics/global.aspx/alliances/en/sizing?c=us&cs=555&l=en&s=biz.● HP sizing tools. These tools are available to assist in selecting HP servers <strong>for</strong> usewith SQL Server. For more in<strong>for</strong>mation, refer tohttp://h71019.www7.hp.com/ActiveAnswers/cache/70729-0-0-0-121.aspx.● Unisys System Sizing Tools <strong>for</strong> SQL Server.

For more in<strong>for</strong>mation, refertohttp://unisys.com/products/es7000__servers/business__solutions/oltp__database__server/sql__server__resources.htm.Validate the TechnologyParallel to the design process, the team will often validate the technologies being used inthe solution. During technology validation, the team evaluates the products ortechnologies to ensure that they work according to specifications provided by their vendorand that they will meet the business needs <strong>for</strong> the specific solution scenario.
<strong>Solution</strong> <strong>Guide</strong> <strong>for</strong> <strong>Migrating</strong> <strong>Oracle</strong> on UNIX to SQL Server on Windows 51SQL Server Editions and FeaturesWhile <strong>Oracle</strong> is available in Personal, Standard, and Enterprise Editions,SQL Server 2000 is available in the following editions:● SQL Server 2000 Enterprise Edition (64-bit)● SQL Server 2000 Enterprise Edition● SQL Server 2000 Standard Edition● SQL Server 2000 Developer EditionAll editions of Windows® XP and Windows Server 2003 include support <strong>for</strong> SQL Server.Support exists <strong>for</strong> many earlier versions of Windows, as well.As with <strong>Oracle</strong>, each edition is distinguished primarily by the availability of certainfeatures, progressing from Personal Edition to Enterprise Edition. SQL Server also offersseveral different editions. Each edition provides functionality based on scale as shown inTable 3.3.Table 3.3: SQL Server 2000 Editions ComparedOSRequirementsand ScalabilityOperating SystemEnterprise (64-bit) Edition* Windows Server2003 EnterpriseEdition* Windows Server2003 DatacenterEditionScalability * Up to 64processors* Up to 512 GB ofmemory* Maximumdatabase size of1,048,516 TBEnterpriseEdition* Windows Server2003 StandardEdition* Windows Server2003 EnterpriseEdition* Windows Server2003 DatacenterEdition* Up to 32processors* Up to 64 GB ofmemory* Maximumdatabase size of1,048,516 TBStandard Edition* Windows Server2003 StandardEdition* Windows Server2003 EnterpriseEdition* Windows Server2003 DatacenterEdition* Up to 4processors* Up to 2 GB ofmemory* Maximumdatabase size of1,048,516 TBFor a detailed preview of all the SQL Server features and supporting tools, refer tohttp://www.microsoft.com/sql/evaluation/features/byfunction/default.asp.For in<strong>for</strong>mation on features by edition, refer tohttp://www.microsoft.com/sql/evaluation/features/choosing.asp.While migrating to SQL Server, the choice of edition of SQL Server that is required tosupport the demands on the database has to be validated. Refer to the followingresource <strong>for</strong> a whitepaper that can aid in choosing the appropriate edition of SQL Server:http://www.microsoft.com/sql/techinfo/planning/SQLReskChooseEd.asp.
