  5. Hardware/Software Requirements • Windows NT 4.0 with SP5 or Later • Internet Explorer 5.0 or Later • SQL Server 6.5 (SP5 or SP3) • SQL Server 7.0 • Connectivity only • With no encryption only need Internet Explorer 4.01 SP2

  6. Editions And Functionality • Enterprise/Developer Edition • Multiple Instance • Failover Clustering • Log Shipping • Parallel DBCC • Parallel Create Index • Index Views • Federated DB Servers • Full-Text Search • Full Replication Support • Standard Edition • Multiple Instance • Graphical Utils • Full-Text Search • Full Replication Support • Personal Edition • Multiple Instance • Graphical Utils • Full-Text (not on 98) • No Subscriber Transactional • Desktop Edition • Multiple Instance • No Subscriber Transactional

  7. SQL Server 2000 Testing • 478 stress tests as compared to 158 for SQL Server 7.0 • Long haul stress • 40 Microsoft® Internal Business Systems versus 24 for SQL Server 7.0 • 201,000 Beta Members • 100+ Rapid Deployment Customers

  8. Some Of The Customers • Buy.com • http://www.microsoft.com/servers/net/buy.htm • Chevron Canada Limited • http://www.microsoft.com/servers/net/chevronca.htm • Lexis-Nexis • http://www.microsoft.com/servers/net/lexnex.htm • Turner Broadcasting • http://www.microsoft.com/servers/net/turner.htm

  9. Security • Registered when… • During server startup • Register/update service connection points • Registers missing databases • Updates database properties • After backup • Customized

  10. Design Considerations • Collations at the DB, column, server level • Multi-instance support • Log shipping • Clustering

  11. Instances { SQL Server 6.5 • Default • Only one active • Version switch • Named • All instances can be active { SQL Server 7.0 or 2000 SQL Server 2000 SQL Server 2000 SQL Server 2000 Up to 15 SQL Server 2000

  12. LogBackups Log Shipping • Database restore not required BACKUP LOG … TO … WITH { NORECOVERY | STANDBY } • Log backups taken on secondary can be applied back on primary • Very useful for planned failover Full Backup

  13. Failover Clustering Installation • No external wizard • Cluster management • Add and remove nodes • Multiple IP addresses • Multiple virtual servers – each with a single instance • No unclustering in SQL Server 2000 when applying service packs • Upgrade to a cluster

  14. Unattended Installation • Generates an (*.iss) File • Integrated as part of the setup • No more k=rc • Now supports upgrade

  15. Upgrading And Working With Access 2000 And SQL Server 2000 • Need SR-1 • Diagrams • Alter but no Save • Access Upsizing Wizard • Warning dialog…

  16. Backward Compatibility With SQL Server 7.0 • Master – target servers • Changes to Backup/Restore • New reserved keywords • COLLATE, FUNCTION, OPENXML • Profiler extended stored procedures have been changed significantly

  17. Backward Compatibility With SQL Server 6.5 • Major changes to backup • Many configuration options changed or set to auto-tune • New keywords • Certain system tables removed • sysprocedures, systasks, sysusages, syslocks, and backup and restore tables

  18. Scalability Enhancements • Federated Database Servers • Allows updateable views of the data • Spread across multiple local or remote instances • Partitioning handled via check constraints • Only one constraint on the column • Must be part of the primary key • Among other considerations….

  19. SRV 3 Orders DB Check CustID > 2,000,000and <=3,000,000 SRV 2 Orders DB Check CustID > 1,000,000and <= 2,000,000 SRV1Orders DB Check CustID <= 1,000,000 Federated Database Servers Total Customer View 1 ~ ~ ~ ~ Insert 2 ~ ~ ~ ~ 3 ~ ~ ~ ~ 4 ~ ~ ~ ~ 5 ~ ~ ~ ~ 6 ~ ~ ~ ~ Update Customers Set CustID = 2,000,001 Where CustID = 1,234 Delete Customers ~ ~ ~ n ~ ~ ~ n 1 ~ ~ ~ ~ ~ ~ ~ n ~ ~ ~ y 2 ~ ~ ~ ~ ~ ~ ~ y ~ ~ ~ y 3 ~ ~ ~ ~ ~ ~ ~ y ~ ~ ~ n 4 ~ ~ ~ ~ ~ ~ ~ n ~ ~ ~ y 5 ~ ~ ~ ~ ~ ~ ~ y 6 ~ ~ ~ ~

  20. Demo 1 • Unattended installation • Now supports upgrade • Federated database servers • Multi-instance support • Distributed partitioned views

  21. Upgrading From 6.5

  22. Pre-Upgrade Checklist(6.5) • Backup all *.dat files • Run DBCC commands • Disk space issues • Need approx. 1.5 times the disk space • Tempdb > 25MB • Tempdb > 10MB free space • Master > 3MB free space

  23. Pre-Upgrade Checklist(6.5) • Ensure all database users have logon information in the master DB so objects are created • If DB1 is the upgrade target but login1 has default database of DB3, DB3 must be upgraded as well • User running upgrade wizard must be administrator on both upgrade and import servers • Two computer upgrade • MSSQLSERVER service needs a domain login account with administrator rights on the local machine

  24. Upgrade Performance (6.5) • 400 MB • < 20 minutes • 1 GB • < 1 hour • 10 GB • < 4 hours • 50 GB • < 12 hours • 100 GB • < 24 hours • Selecting data validation can increase this time two-fold

  25. Performing The Upgrade • Data transfer method • Tape or named pipes conversion • Upgrade verification options • Choosing the databases to upgrade

  26. SQL Upgrade Wizard • Options • Objects to transfer • Server configuration • Replication settings • SQL Executive settings • ANSI NULLS ON|OFF • QUOTED_IDENTIFIERS ON|OFF

  27. Database Layout • Database files • MDF in location of first data device • LDF in location of first log device • Multiple database files • 1 MDF for the bulk of the data • Minimal size MDF”s for each other data device • 1 LDF for the bulk of the log • Minimal size LDF’s for each other log device • Have the ability to customize

  28. 100MB Data 200MB Data Min Size Data 100MB Data 100MB Log 200MB Log 100MB Log Min Size Log Database Layout • Default Behavior • Can Customize in Wizard or with Script Data Logs

  29. Setup Files Troubleshooting • Placed in the Upgrade Directory • Specific directory for each DB upgraded • Naming convention Errors will appear as follows: MSSQL\Upgrade\<SERVERNAME_DATE_TIME> will contain *.ERR files Inconsistency in Database Objects MSSQL\UPGRADE\<SERVERNAME_DATE_TIME>\CHECK65-<DBID>-<DBNAME>_ERR.OUT

  30. Demo 2 • Upgrade a 6.5 Database to SQL Server 2000

  31. Pop Quiz • How do you browse for SQL Servers in the Active Directory™? • With standard Active Directory browsing tools • What SQL Server feature lets you horizontally partition databases? • Federated database servers • What three new keywords exist in SQL Server 2000 when upgrading from 7.0? • Collate, OpenXML, Function

  32. Upgrading From 7.0

  33. Upgrade Methods • Installation upgrade • Upgrades the server in place • Left with a SQL Server 2000 server alone • Backup and restore • Only restore 7.0 databases • No upgrade for: • Attach and detach • You can attach a 7.0 database onto a SQL Server 2000 server MSDB Model Distribution Master

  34. Demo 3Part A and Part B • Upgrade via Backup • Upgrade via Detach and Attach

  35. CDW Architecture Data flow Destination SQL Server 2000 Source SQL Server 7.0 or 2000 PULL 3: SQL Agent Executes DTS Pkg Connect toSrc. and Dst. Server 1: Read DB and Schema information 2: Create DTS Package on Destination Copy Database Wizard NOTE: All Processes run on Destination

  36. CDW Restrictions • Database Name Changes During the Copy/Move Are Not Allowed • Limitations • Replicated • Log Shipped • Windows® 9x sources need to create share • SysAdmin rights • SQLAgent run under domain account

  37. Demo 3Part C • Copy Database Wizard

  38. Post-Installation Issues

  39. Backward Compatibility Levels • Use as an interim migration aid • Upgrade from 7.0 compatibility is changed to 8.0 • Upgrade from 6.5 compatibility level is maintained • Sp_dbcmptlevel • Enterprise manager

  40. Full-Text Indexes And Stats • After upgrade… • Databases need to be full-text enabled • Catalogs need to be repopulated • Statistics for Tables/Indexes need to be repopulated • Sp_updatestats

  41. Replication • Order of upgrade • Distributor > Publisher > Subscriber • Immediate update concerns • Need to upgrade both Publisher and Subscriber before replicating data • Drop the publication and all subscriptions • Drop the timestamp column from pub and sub tables • Re-create the publication • Rows now use a uniqueidentifer column instead of a timestamp

  42. Replication • FTP Replication • Properties now stored at publisher so no need to change each subscriber • But… • FTP replication will be turned off after upgrade • Only affects Snapshot or Merge/Transactional publications that need a snapshot

  43. Profiler • Profiler in SQL Server 7.0 had a set of extended stored procedures • Used to implement custom trace programs • All have been changed • C2 security enhancements • Profiler no longer drops trace elements when under heavy load

  44. Imaging And Server Rename Issues • Imaging a SQL Server for distribution…. • Required dealing with name changes manually • SQL Server 2000 changes this • Server name is detected on the first boot after install • If different than that stored in SQL Server, SQL Server is updated

  45. Configuring The Server • Memory • Dynamically allocated by default • Security settings • Windows authentication • SQL Server and Windows • Connections • Upgrading from 6.5 no longer a hard cap • Ability to change default DB and file locations

  46. Backup And Restore Considerations • Many database options have changed • Select Into/BulkCopy • Truncate Log on Ckpt. • Recovery Models • Simple • Bulk-Logged • Full

  47. Using SQLDIAG.EXE • SQLDIAG.EXE • Located in the program files\microsoft sql server\Binn directory • Outputs by default to program files\microsoft\sql server\log directory • Outputs information on current processes, configuration information, databases, etc.

  48. Demo 4 • Updating full-text indexes and statistics • Setting server configuration settings • Understanding recovery models • Using SQLDIAG.EXE

  49. Pop Quiz • What feature of replication is disabled after upgrade? • FTP replication • What recovery model minimizes logging but still let’s you use log backups? • Bulk-logged • When upgrading from SQL Server 6.5, what compatibility level is maintained by default? • 6.5 • What two ways can you change compatibility level? • Sp_dbcmptlevel and the Enterprise Manager

  50. Microsoft Curriculum Courses • 2071 • Querying Microsoft SQL Server 2000 using Transact-SQL • 2072 • Administering Microsoft SQL Server 2000 • 2073 • Implementing a Database Design on Microsoft SQL Server 2000
