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

21. 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

Manageability and Installation

30. 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

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

32. IC Deployment OUI Xcopy Use the installer as you normally would
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

33. 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\<version>\DllPath
5. Windows System Path setting
