3 ODP.NET Core Production Release 3

4 .NET Core New CLR released from Microsoft Open source Multi-platform Subset of.net Framework APIs and new APIs too Code-based configuration 4

5 ODP.NET Core Very Similar to Managed ODP.NET 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 5

6 ODP.NET Core RTM Available on nuget.org Oracle version 18.3 NuGet version Adds Red Hat Linux support since beta Connectivity to Oracle Database 11.2 and higher 6

7 ODP.NET Core System Requirements.NET version support.net Core 2.1 and later.net Framework 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 Oracle Linux 7.x Red Hat Enterprise Linux 7.x 7

8 D E M O N S T R A T I O N ODP.NET Core

9 ODP.NET Core on Oracle Linux Configuration Steps Install.NET Core SDK by running the following from Oracle Linux host: sudo rpm -Uvh sudo yum update sudo yum install dotnet-sdk-2.1 Instructions page 9

10 D E M O N S T R A T I O N Deploying ODP.NET Core to Linux on Oracle Cloud

11 Demo Resources You Can Try It Yourself Oracle Cloud Infrastructure Oracle Linux running on compute Oracle Database Cloud Service ODP.NET Core also works with Oracle Autonomous Database Free cloud credits: 11

12 Installation ODAC 18c 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 13

13 Oracle Database 18c Express Edition (XE) Free DB for developers 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 14

14 ODP.NET Core Configuration API 15

15 ODP.NET Core Classes New Configuration APIs 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 16

16 ODP.NET Core Configuration API Code Sample // Add connect descriptors and net service names entries. OracleConfiguration.OracleDataSources.Add("orclpdb", "(DESC... OracleConfiguration.OracleDataSources.Add("orcl", "(DESCRIP... // Set ODP.NET command properties OracleConfiguration.StatementCacheSize = 25; OracleConfiguration.SelfTuning = false; OracleConfiguration.BindByName = true; OracleConfiguration.CommandTimeout = 60; OracleConfiguration.FetchSize = 1024 * 1024; // Set network properties OracleConfiguration.SendBufferSize = 8192; OracleConfiguration.ReceiveBufferSize = 8192; OracleConfiguration.DisableOOB = true; 17

17 D E M O N S T R A T I O N ODP.NET Core Configuration API

18 Migrating from Managed ODP.NET to ODP.NET Core Changes to Make 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 19

19 ODP.NET Core Future Directions 20

20 ODP.NET Core Future Directions Windows only features LDAP Event Log Performance Counters.NET Core 3.0 Entity Framework Core 22

21 ODP.NET Entity Framework Core Beta Release 23

22 Oracle Entity Framework Core Beta Release will be on nuget.org Namespace: Oracle.EntityFrameworkCore For beta, remember to check Include pre-release box Supports Entity Framework Core 2.1 and higher Oracle EF Core supports the same OSes as ODP.NET Core 24

23 Oracle Entity Framework Core Setup Runtime dependencies Oracle.EntityFrameworkCore Design time dependency Microsoft.EntityFrameworkCore.Design Connection and provider configuration using extension method <Connection String>"); 25
