  1. New Oracle Features for .NET Developers Alex Keh Principal Product Manager Server Technologies

  2. Agenda <Insert Picture Here> • Oracle on .NET Themes • Ease of Development • Performance • Manageability and Installation

  3. <Insert Picture Here> Oracle on .NET Themes

  4. New .NET Feature Themes • Ease of Development • Tight integration with Visual Studio 2005 and 2008 • Improve productivity for ASP.NET development • Objects/UDTs/ADTs • Performance • Expose new tuning features • Improve performance out of the box • Manageability and Installation • Deployment: smaller client and easier packaging

  5. <Insert Picture Here> Ease of Development

  6. Ease of Development – Visual Studio • Fully integrated with Visual Studio 2005 and 2008 • Server Explorer • Data Sources Window • Data Source Configuration Wizard • Dataset Designer • TableAdapter Configuration Wizard • Query Builder/Query Designer • More • Automatic code generation – Winform and ASP.NET • Data Sources Window • Integration with SQLDataSource control • Makes ASP.NET web application development very easy

  7. Ease of Development – Visual Studio • New Oracle Wizards and Designers • Grant/Revoke Privileges Wizard • Import Table Wizard – Migrate tables/data from databases, Excel, Access • Object, VARRAY, Nested Table Designers • UDT Custom Class Code Generation Wizard • Full Oracle UDT Support • View UDT’s in Server Explorer • CRUD operations on UDTs in tables and views • Use UDT types in other Wizards (eg Table designer) • Oracle Data Window Enhancements • Customizable – control how many rows are fetched

  8. Ease of Development – Visual Studio • New Oracle Database Project • Manage, Edit and Run SQL scripts • SQL*Plus is built in • Source control integration – SourceSafe and Team Foundation Server • Oracle Query Window • New UI • Explain Plan • Auto-commit toggle • ODT Options page • Customize how you use ODT

  9. D E M O N S T R A T I O N New ODT Features

  10. Ease of Development – UDTs Benefit: Simplify Oracle UDT application development Optimum for Spatial and other object developers UDT development – data access Oracle data types Objects Mapped to .NET custom objects Collections (Varrays and Nested Tables) Mapped to .NET custom objects and arrays REF ODP.NET OracleRef can represent Oracle REF Custom type factory and custom type required Custom type factory instantiates the custom type Custom types define mapping between UDT attributes/elements and .NET type members

  11. Ease of Development – UDTs UDT development - tools Create, view, and modify UDTs and their specifications Designers for Varrays, Nested Tables, and Objects Designers for Object tables and views New tree control nodes for UDTs Custom Class Wizard Automatically generate .NET custom type from existing Oracle Collections and Objects Generates C#, VB.NET, or C++

  12. D E M O N S T R A T I O N UDTs

  13. Oracle Providers for ASP.NET • Pre-built services to store website state into Oracle • Services for commonly used website information • E.g. user info, user roles, shopping cart • Easy to learn • Based on standard ASP.NET provider APIs and schema • Inherits from .NET Framework 2.0 base classes • Compatible with ASP.NET service classes • No unique extensions in Oracle ASP.NET providers

  14. Oracle Providers for ASP.NET • Seamless integration with ASP.NET services and controls • Reference to specific providers unnecessary • High level of abstraction: services and controls based programming • Easy to switch from SQL Server to Oracle quickly • Configuration file determines which data source to use • Easy to setup and manage • Can be managed by IIS or Website Admin Tool

  15. Oracle Providers for ASP.NET IIS ASP.NET Controls ASP.NET Services Oracle Providers for ASP.NET ODP.NET

  16. Available Providers • Oracle Providers for ASP.NET components • Membership Provider • Role Provider • Profile Provider • Session State Provider • Site Map Provider • Web Parts Personalization Provider • Web Event Provider • Cache Dependency Provider • Administrators pick which provider(s) to use • Most providers are independent of one another

  17. D E M O N S T R A T I O N ASP.NET Providers

  18. <Insert Picture Here> Performance

  19. Performance – Data Retrieval (11g) • Client Result Cache • Automatically caches results sets on client • No .NET code changes required to use • Accessible across the same process to different sessions with same user settings • Cache remains consistent via DB Change Notification • Improved statement caching • Cache ODP.NET parameter contexts • Better LOB performance • LOB prefetching – fewer roundtrips • Even more LOB performance improvement using SecureFiles

  20. Performance – Loading External Data • Load external data quickly into Oracle database programmatically • ADO.NET 2.0 Bulk Copy • Direct data upload from .NET to Oracle • Excellent for large amounts of external data • Performance comparable to SQL*Loader

  21. Performance – 64-bit • Allow ODP.NET and .NET stored procedures to use more scalable 64-bit hardware (10.2.0.3) • Windows x64 • 64-bit ODP.NET • 64-bit .NET Stored Procedures • Windows Itanium • 64-bit ODP.NET • 64-bit .NET Stored Procedures • Available for download on OTN from .NET Center

  22. <Insert Picture Here> Manageability and Installation

  23. Instant Client (IC) • IC available with OUI and xcopy • No functionality difference between IC and standard client • IC Benefits • Control over install process • Xcopy • Fine grain control over installation process • Great for large scale deployments or ISV packaging • OUI – great for small scale deployments • Smaller install size compared to standard install • Xcopy install – smallest footprint • OUI install – small footprint • Fastest client deployment – Xcopy install

  24. New Instant Client Components • ODP.NET • Oracle Providers for ASP.NET • Oracle Provider for OLE DB • OO4O • Oracle Services for MTS

  25. IC Deployment • OUI • Use the installer as you normally would • Xcopy • Step 1: Unzip and copy IC files to disk • Step 2: Run install.bat • Provide parameters specifying product(s) to install, Oracle Home name, and target location • Step 3: Add installation directories to Windows PATH • Step 4: Modify NLS_LANG to desired locale

  26. Managing Multiple Oracle Homes in .NET • Solution for ODP.NET 10.2.0.4 and higher • ODP.NET reads .NET config files for location of unmanaged Oracle DLLs • Each app can use different Oracle client DLLs even if same ODP.NET managed version is used • DLL search order • 1. Current application directory • 2. Application config or web.config • 3. Machine.config • 4. Windows Registry • HKLM\Software\Oracle\ODP.NET\<version>\DllPath • 5. Windows System Path setting
