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
- 15. Oracle Explorer
- 16. Designers and Wizards • Table Designer • View Designer • Stored Procedure/Function Wizard • Package Wizards • Sequence Designer • Synonym Designer • Trigger Designer • Data Adapter Wizard
- 17. Table Designer
- 18. 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
- 19. 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

- 31. Supported Platforms • Windows only • .NET Framework 1.1 • Oracle 10.2 or later
- 32. When to use • Ease of development • Computationally intensive code • Leverage .NET programming expertise • Leverage existing .NET code libraries • Windows platform only
- 33. Install • “Custom” install of “Oracle Database Extensions for .NET” is required • DBCA performs configuration • CLR Service created and started • Service is named <OracleHomeName>ClrAgnt
- 34. 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
- 35. 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.
- 36. 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. D E M O N S T R A T I O N Your First .NET SP
- 38. 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 • Edit Service <OracleHomeName>ClrAgnt • Example: ORACLE_HOMEbinoraclragnt.exe agent_sid=CLRExtProc max_task_threads=5
- 40. 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
- 41. 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
- 42. Controversy of Oracle in last year >> Oracle has been making waves inside and outside the company this year. Hardware channel exec Mitch Breen left in January and sources told CRN at the time that Oracle's direct sales team was battling both internally and with channel partners >> Meanwhile, Oracle has had two earnings calls that failed to impress Wall Street. That didn't stop CEO Larry Ellison from bashing Oracle's competitors and vowing an all- out assault on the SaaS and PaaS markets >> Ellison also said Oracle's new in-memory database technology is so fast, some customers who tested it thought it was broken because they didn't realize it had already performed its functions. This despite the fact that Oracle came late to this market and has lots of catching up to do
