  4. Agenda • Introduction • Oracle Developer Tools for VS.NET • .NET Stored Procedures Demo • Oracle Data Provider for .NET New Features • ODP.NET demo – DB Change Notification

  5. Oracle Developer Tools for Visual Studio .NET • Tightly integrated “Add-in” for Visual Studio .NET • Oracle is a premier-level partner in MS Visual Studio Industry Partner Program (VSIP) • Available for free download now • http://otn.oracle.com/dotnet

  6. Develop on Windows, Database on any platform Windows Oracle Developer Tools for VS.NET Linux Visual Studio Environment Unix Windows Other Oracle 10g, 9i, or 8i

  7. Benefits • Easy to learn and intuitive • Leverage your SQL Server experience • Powerful features that enhance productivity – e.g. designers, code generation • Exposes native Oracle functionality not typically available in generic tools • Stay in Visual Studio for more of your project’s lifecycle

  8. Feature Overview • Oracle Explorer – browse and alter schema • Wizards & Designers • Automatic Code Generation • PL/SQL Editor with intellisense • Oracle Data Window • Oracle Query Window (Ad Hoc SQL) • Integrated Help System – SQL, PL/SQL Keywords

  9. demo Oracle Developer Tools

  10. 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

  11. Designers and Wizards • Table Designer • View Designer • Stored Procedure/Function Wizard • Package Wizards • Sequence Designer • Synonym Designer • Trigger Designer • Data Adapter Wizard

  12. Automatic code generation • Drag and drop a schema object from Oracle explorer • Generated code uses OracleDataAdapter class (ODP.NET) • Data Adapter Wizard can be run to customize • Generate “typed datasets” as needed

  13. PL/SQL Code Editor • Syntax Coloring • Collapsible regions • Intellisense • Context sensitive help for SQL and PLSQL Keywords and Datatypes • Intelligent Error display in task list • Context sensitive help for Oracle error numbers

  14. Data Window • View and Update Table data • Run Stored procedures and view data • Supports Oracle datatypes • View complex data types such as Ref Cursors

  15. Oracle Query Window • Execute “Ad Hoc” SQL • Drag and drop objects from Oracle Explorer to generate SQL • Result of select statements in choice of grid or text format • Execute multiple statements in a row • Run scripts (“@myscript.sql”)

  16. 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

  17. Coming Soon • PL/SQL Debugging • Many other features…..

  18. Agenda • Introduction • Oracle Developer Tools for VS.NET • .NET Stored Procedures Demo • Oracle Data Provider for .NET New Features • ODP.NET demo – DB Change Notification

  19. Oracle Database Extensions for .NET • Oracle 10g Release 2 on Windows • Supports C#, VB.NET, C++ Stored Procedures • Build assembly in Visual Studio .NET • Deploy from Visual Studio .NET using Deployment Wizard

  20. Write .NET Stored Procedures for Oracle Oracle Developer Tools for VS.NET Client Application Visual Studio Environment Develop Invoke C#,VB.NET,C++ Server Project (UseODP.NET If required) Stored Procedure, SQL .. Invoke Deploy Build Assembly foo.dll (proc sp) Oracle DB Extensions for .NET Stored Proc

  21. Creating a .NET SP • 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 • 5) Call .NET SP as you would any other SP

  22. demo Creating and Deploying a .NET Stored Procedure into Oracle

  23. Agenda • Introduction • Oracle Developer Tools for VS.NET • .NET Stored Procedures Demo • Oracle Data Provider for .NET New Features • ODP.NET demo – DB Change Notification

  24. ODP.NET 10g Release 2 Themes • Better ease of use • More flexibility • Access to advanced Oracle DB features • Faster performance

  25. ODP.NET - RAC and Grid • Automatic connection cleanup • ODP.NET frees connections to bad nodes automatically • Set connection pool parameter • “HA events = true” • Works with 10gR2 RAC • Runtime connection load balancing • Connections divided among nodes based on metrics and admin policies • Set connection pool parameter: • “load balancing = true” • Works with 10gR2 RAC

  26. ODP.NET - DB Change Notification • When a DB data change occurs, client app using the data is notified • Change in a query result set, schema objects, or the state of the database • Works with 10gR2 DB • Properties • Create/Remove DB change notifications • Group multiple notifications into one registration • Persist notifications on DB server

  27. Change Notification Process • 1. When command is executed, the notification registration is created in the DB • 2. ODP.NET starts the application listener upon notification registration • 3. When a change occurs, the application is notified through either • Callback - event delegate assigned to the OracleDependency.OnChange event property • Polling - OracleDependency.HasChanges property

  28. Setting up ODP.NET Change Notification • 1. Create OracleDependency • 2. Assign event handler to OracleDependency.OnChange event property • Event handler invoked when the change notification is received • 3. Set the port for the listener to listen on • 4. Bind the OracleDependency instance to the OracleCommand with the query • Internally, the DB change notification request is created and assigned to the OracleCommand.Notification property

  29. demo DB Change Notification

  30. ODP.NET - Connection Pool Management • Explicitly refresh connections in a pool or pools • Clear connections from a pool or pools • One pool - Execute OracleConnection.ClearPool method • All pools – Execute OracleConnection.ClearAllPools method • Works with 10gR2 and earlier DBs

  31. ODP.NET - LOB (and LONG) Retrieval • Faster performance • Fewer DB round trips for LOB retrieval • Transparent to developer • Works with 10gR2 DB • More tunable and usable • Full LOB functionality when InitialLOBFetchSize > 0 • GetOracleBlob() and GetOracleClob() methods in OracleDataReader supported • InitialLOBFetchSize can be up to 2GB • Works with 10gR2 DB

  32. ODP.NET - Security • Application security context • ODP.NET can set the Client Identifier in the Application Context for every database session • Similar to proxy user authentication, but requires only one session and no pre-created proxy user • Set OracleConnection.ClientIdentifier = “gold customer” • Works with 10gR2 and earlier DBs

  33. ODP.NET - Additional Features • Input REF Cursors into PL/SQL • Only works when REF Cursor is output from PL/SQL first • Works with 10gR2 DB • ODP.NET works with .NET Stored Procedures • Additional ADO.NET 2.0 features for ODP.NET in 2nd half 2005

  34. Next Steps • Come to the Oracle booth (Exhibition Hall Stand A21) for a one on one demonstration with .NET experts • Next Session: SVR340 Oracle on Windows Thu Jul 7 10:15 - 11:30 Room: 2c • .NET Developer Center - free downloads, demos, walkthroughs, and whitepapers • http://otn.oracle.com/dotnet • Oracle Developer Tools & .NET Stored Proc questions?
