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

Introduction





ODP.NET 10g Release 2 Themes

Better ease of use

More flexibility

Access to advanced Oracle DB features

Faster performance

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

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

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

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

demo

DB Change Notification

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

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

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

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

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
