- 12. D E M O N S T R A T I O N Oracle Developer Tools - Drill Down
- 13. Oracle Explorer • Tree control, similar to “Server Explorer” • View Oracle schema objects • Generate SQL for schema objects • Filter hides unwanted schema objects • A starting place for most tasks • View, alter, create schema objects • Auto generate code • View and edit Oracle data • Run stored procedures and functions
- 14. Oracle Explorer
- 15. Designers and Wizards • Table Designer • View Designer • Stored Procedure/Function Wizard • Package Wizards • Sequence Designer • Synonym Designer • Trigger Designer • Data Adapter Wizard
- 16. Table Designer
- 17. Automatic Code Generation • Drag and drop a schema object from Oracle Explore • Generated code uses OracleDataAdapter class (ODP.NET) • Data Adapter Wizard can be run to customize • Generate “typed datasets” as needed
- 18. PL/SQL Code Editor • Syntax Coloring • Collapsible regions • IntelliSense • Context sensitive help for SQL/PLSQL keywords • Intelligent error display in task list • Context-sensitive help for Oracle error numbers
- 20. Data Window • View and update table data • Run stored procedures and view data • Supports Oracle data types • View complex data types such as Ref Cursors
- 21. Data Window
- 22. Oracle Query Window • Execute “ad hoc” SQL • Drag and drop objects from Oracle Explorer to generate SQL • Result of select statements in grid or text format • Execute multiple statements in a row • Run scripts (“@myscript.sql”)
- 23. Integrated Online Help • Getting started • Walkthroughs • Oracle Developer Tools Reference Guide • Context sensitive help for UI elements • Context sensitive SQL and PLSQL keywords • Oracle Error Manual • Oracle SQL Reference Guide • Oracle PL/SQL Reference Guide

- 26. Agenda • Oracle Developer Tools for Visual Studio .NET • Overview • Demo - drill down • Oracle Database Extensions for .NET • Overview • Demo – My First SP • Tuning and Data Access • Demo – Data Access in a SP • Demo – Debugging a .NET SP
- 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
- 28. Architecture
- 29. Write .NET Stored Procedures for Oracle Visual Studio Environment Oracle Developer Tools for VS.NET Oracle DB Extensions for .NET C#,VB.NET,C++ Server Project (Use ODP.NET if required) Assembly foo.dll (proc sp) Build Develop Stored Proc Stored Procedure, SQL .. Client Application Invoke Invoke Deploy
- 30. Supported Platforms • Windows only • .NET Framework 1.1 • Oracle 10.2 or later
- 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.
- 36. D E M O N S T R A T I O N Your First .NET SP
- 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
- 38. Performance Tuning • Edit Service <OracleHomeName>ClrAgnt • Example: ORACLE_HOMEbinoraclragnt.exe agent_sid=CLRExtProc max_task_threads=5
- 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
- 41. D E M O N S T R A T I O N .NET SP Data Access
- 42. D E M O N S T R A T I O N .NET SP Debugging
