ODP.NET CoreProduction Release

3


.NET Core

•New CLR released from Microsoft

•Open source

•Multi-platform

•Subset of .NET Framework APIs and new APIs too

•Code-based configuration

4


ODP.NET Core

•Same namespaces, APIs, and DLL name as managed ODP.NET

•Supports Easy Connect, sqlnet.ora, and tnsnames.ora

–Place *.ora files in

• Directory set in OracleConfiguration.TnsAdmin property

• Directory of the running ODP.NET Core assembly

• Current working directory

•No .NET configuration file nor environment variable support

Very Similar to Managed ODP.NET

5


ODP.NET Core

•Available on nuget.org

–https://www.nuget.org/packages/Oracle.ManagedDataAccess.Core/

•Oracle version 18.3

•NuGet version 2.18.3

•Adds Red Hat Linux support since beta

•Connectivity to Oracle Database 11.2 and higher

RTM

ODP.NET Core

• .NET version support

–.NET Core 2.1 and later

–.NET Framework 4.6.1 and later

–.NET Standard 2.0

•Windows and Linux support

–Same Windows versions as ODP.NET 18c: 7, 8.1, 10, 2012, 2012 R2, and 2016

Deploying ODP.NET Core to Linux on Oracle Cloud


Demo Resources

• Oracle Cloud Infrastructure

–Oracle Linux running on compute

• Oracle Database Cloud Service

–ODP.NET Core also works with Oracle Autonomous Database

• Free cloud credits: https://cloud.oracle.com/tryit

You Can Try It Yourself

11

https://cloud.oracle.com/tryit


Installation

•ODP.NET Core available with

–NuGet, MSI, and OUI bundles only

–Not in xcopy bundle

•ODP.NET Core packaged as NUPKG only

–Install using NuGet package manager or command line (i.e. nuget.exe, dotnet.exe)

–Once installed, can be xcopy deployed

• Installation on Linux is NuGet only

ODAC 18c

13


Oracle Database 18c Express Edition (XE)

•Linux version available now

•Windows version very soon

•Free for dev, production, and redistribution

• (Almost) all features as Enterprise Edition + options

•No patches, but…

–New XE version every year

• Follows the DB on-premises release

• i.e. 19c, 20c, 21c, etc.

•CPU, memory, and hard disk limits

Free DB for developers

14


ODP.NET CoreConfiguration API

15


ODP.NET Core Classes

•OracleConfiguration class

–Used to programmatically set ODP.NET configuration settings

•OracleDataSourceCollection class

–Configure network service names (i.e. TNS) to connect to Oracle DBs

•OracleOnsServerCollection Class

–Logical servers and corresponding node list where Oracle Notification Service (ONS) daemons talk to remote clients

New Configuration APIs

16


ODP.NET Core Configuration APICode Sample

17

// Add connect descriptors and net service names entries.OracleConfiguration.OracleDataSources.Add("orclpdb", "(DESC...OracleConfiguration.OracleDataSources.Add("orcl", "(DESCRIP...

// Set ODP.NET command propertiesOracleConfiguration.StatementCacheSize = 25;OracleConfiguration.SelfTuning = false;OracleConfiguration.BindByName = true;OracleConfiguration.CommandTimeout = 60;OracleConfiguration.FetchSize = 1024 * 1024;

// Set network propertiesOracleConfiguration.SendBufferSize = 8192;OracleConfiguration.ReceiveBufferSize = 8192;OracleConfiguration.DisableOOB = true;



ODP.NET Core Configuration API


Migrating from Managed ODP.NET to ODP.NET Core

•Assembly – use ODP.NET Core Oracle.ManagedDataAccess.dll

• .NET configuration – migrate to code-based configuration

•Tnsnames.ora and sqlnet.ora configuration – no changes

•Namespace – no changes

•APIs – Minimal to no changes

Changes to Make
