13 Manageability Goals  Integrated Management, Rich UI  Scale down time/effort for common management tasks  Server Transparency  Everything scriptable

14 Management Studio  Integrated management  Relational DB, Analysis Services, Reporting Services, Notification Services, SQL Server CE…  Multiple versions of SQL Server from one interface  Integrated with DTS  Rich management & authoring  Performance  Manage multiple servers, MANY objects  Operations: Profiler, Query Analyzer

15 Manageability - Tools  New: SQL Server Management Studio  New Rich GUI  Integrated Authoring, Management  Support all SQL Server components  New: Management Objects (SMO)  Managed code, new design patterns  Improved Scalability, Scripting  New: SQLCMD  High Performance CMD line tool  New: SQLiMail Replacement  SMTP Support, Cluster Support, No Outlook required

16 Demo – Tools, SQLiMail, SQLCMD

17 Manageability - Tuning  Database Tuning Advisor  Time Bound Tuning  What-If Analysis  Scalability  XML Show Plan  Publicly available Schema  Programmatic Access  Portability

18 Demo – Tuning

19 Manageability - Diagnostics  Dynamic Management Views  Server Transparency  “sys.memory_clerks” – how much memory is each component consuming ?  “sys.schedulers” – Is a scheduler hung ?  SQL Trace  Query data from live traces  SQL Profiler  Deadlock and ShowPlan Visualization

20 General Server DMVs and DMFs  dm_exec_*  Execution of user code and associated connections  dm_os_*  Memory, locking & scheduling  dm_tran_*  Transactions & isolation  dm_io_*  Input/Output on network and disks  dm_db_*  Databases and database objects

23 Addressing Barriers to Availability  Database Server Failure  Failover Clustering  Database Mirroring  Database Maintenance & Operations  Online Index Operations  Fast Recovery  Fine-Grained Online Repairs  Data Access Concurrency Limitations  Snapshot Isolation  User, Application Errors  Database snapshots

24 Microsoft Cluster Services  Supported in Microsoft® SQL Server™ 7  Enhanced in Microsoft® SQL Server™ 2000  Further refined in SQL Server 2005  More nodes (match operating system limits)  Unattended setup  All SQL Server services participate  Database Engine, SQL Server Agent,  Analysis Services, Full-Text Search, etc.

25 Database Mirroring Achieving high availability while managing costs  Database Failover  Very fast failover…less than 3 seconds  Automatic or manual failover  Automatic, transparent client redirect  Database Snapshots for Reporting  Works with standard hardware and storage Mirror Principal Witness LogLog Application SQL Server DataDataDataDataLogLog

26 Database Mirroring OptionWitnessExplanation Synchronous with automatic failover (high availability) Yes (required) To maximize availability, uses a witness server instance to support automatic failover. Asynchronous (high performance) Null (if exists, not used) To maximize performance, the mirror database always lags somewhat behind the principal database, never quite catching up. However, the gap between the databases is typically small. Synchronous (high protection) No To maximize protection of the data, the principal server cannot run without the mirror server.

27 Online Index Operations  Online index maintenance  Create, Rebuild, Reorganize, Drop, Add or drop constraint  Fully parallel  Online/offline are both supported

28 Other Availability Features  On-Line Page and File restore  Database remains online - Only data being restored is unavailable  Dedicated Admin Connection  Access to Server when regular connections fail  Fast Recovery  Database is available when undo begins UndoRedo Available

29 Demo – Admin connection

30 Snapshot Isolation  Increased data availability for read applications  Allows non-blocking consistent reads in an OLTP environment  Writers don’t block readers  Readers don’t block writers  Scenarios  Read-mostly database with relatively few writes – Reporting  Migration from Oracle to SQL Server

31 Database Snapshots  Snapshot of a database at a point in time  Created instantly  Read only  Does not require a complete copy of the data  Shares unchanged pages of the database  Requires extra storage only for changed pages  Uses a “copy-on-write” mechanism  Recover from User, Application or DBA error  Rewind database to Database Snapshot

32 Demo – Database Snapshot

33 Range Partitioning  Range Partitioning breaks a single object into multiple manageable pieces  Partitioning is transparent to the application  Partitioning applies to  Tables  Indexes  The row is the unit of partitioning  All partitions reside in a single database

34 Partition Manageability  Common operations  Split, merge, add, and drop partitions  Bulk data loading, Index maintenance  Switch data instantly between  Table and partition of another table  Two partitions of different tables Time Sliding Window Archived HotRead-OnlyNear-LineRead-Mostly Obsolete

35 SQL Server 2005 Security Initiatives Focus on security, privacy, and tools  Enhanced security features  Encryption and decryption of data with key management  Advanced auditing, authentication, and authorization  Reduction in surface area  More optional installation options  Minimized Attack surface: Features require explicit configuration  Deployment improvements  Integration with Microsoft Update services  Common Criteria  Certification targeted at EAL4+ around RTM  Security Tools  Continued MBSA investments  Best Practices Analyzer
