Oracle Database XE. • Whitepapers• Sample Code• Demo Videos• Help Forums• “How to” step by step tutorials• Latest Oracle on .NET News


New Feature 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


• 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


• 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++


UDTs


• 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


• 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


IIS

ASP.NET Controls

ASP.NET Services


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


ASP.NET Providers


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 (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


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 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


Client Deployment
