Oracle on.NET Themes

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

Ease of Development

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

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

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

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

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

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++

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

Ease of Development – Grid Automated ODP.NET failover to Data Guard instance HA DB Down event ODP.NET receives DB down events Frees all pooled connections to the downed DB Configuration Set “HA Events = true” in connection string Events for service, service member, node, and database down Works with Data Guard Works with 11g and 10.2 DB server

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

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

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

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

Performance

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

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

Performance – 64-bit Allow ODP.NET and.NET stored procedures to use more scalable 64-bit hardware ( ) 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

Manageability and Installation

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

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

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

Managing Multiple Oracle Homes in.NET Solution for ODP.NET 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\ \DllPath 5. Windows System Path setting
