27. Oracle Database Extensions
for .NET
• Oracle 10g Release 2 on Windows
• Write Microsoft Visual C# or Visual Basic .NET
stored procedures/functions
• Build assembly in Visual Studio .NET
• Deploy from Visual Studio .NET using .NET
Deployment Wizard
31. When to use
• Ease of development
• Computationally intensive code
• Leverage .NET programming expertise
• Leverage existing .NET code libraries
• Windows platform only
32. Install
• “Custom” install of “Oracle Database
Extensions for .NET” is required
• DBCA performs configuration
• CLR Service created and started
• Service is named <OracleHomeName>ClrAgnt
33. Creating a .NET Stored
Procedure
1. Use Visual Studio .NET to build a .NET
procedure or function in the usual way
2. If data access is required, use ODP.NET
classes
3. Result is a .NET assembly
4. Run .NET Stored Procedure Deployment
Wizard (included with Oracle Developer Tools)
5. Call .NET stored procedure as you would any
other Oracle stored procedure
34. Stored Procedure
Requirements
• Be declared a public static method.
• Not be a constructor or a destructor.
• Use parameter types that are compatible with
the Oracle native database types.
35. Security Levels
• Safe - Access only to database resources.
• External - Read or write to local files, and
access to network resources such as sockets
and internet nodes
• Unsafe- Unrestricted execution including
execution of unmanaged code. It is a superset
of all other security levels.
37. OraCLRAgent Service
• Multithreaded Agent Architecture
• Optimized for security and performance
• A separate multithreaded process is started for
each system identifier
• Each TNS listener that is running on a system
listens for incoming connection requests for a set
of SIDs.
• As system load thresholds are met, additional
processes are spawed
39. Performance Tuning
• max_sessions – (25) Number of maximum
sessions
• max_task_threads – (6) Number of maximum
task threads
• max_dispatchers – (2) Number of maximum
dispatchers
40. ODP.NET Server Side
Differences
• Failover/Notifications, Transaction and
Connection classes have differences
• No transactions can be started, committed, or
rolled back from within a .NET SP that uses
the default connection of the caller
• Regular transaction symantics apply if a new
connection is opened in the SP
43. Next Steps
• .NET Developer Center - http://otn.oracle.com/dotnet
