ASP.NET Providers

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

Manageability and Installation

Instant Client XCopy Deployment

• Zip package of binaries• Install done manually or through a third-party installer easily• Great control over the installation process

• Install process• Step 1: Copy IC files to disk• Step 2: Run install.bat• Step 3: Add installation directories to Windows PATH• Step 4: Modify NLS_LANG to desired locale

XCopy Install.bat

Instant Client (IC) XCopy Install

• Easiest to package/install• Xcopy – administrators script to specific requirements,

generally large deployments• OUI – for small scale deployments

• Smallest client footprint• Xcopy

• Fastest client deployment• Xcopy

• No difference in the functionality of each client component included• Not all client components are part of Instant Client xcopy

install
