ODAC 12c Release 3 and 4


Major New Features

• Visual Studio 2015

• Offline Schema Compare

• Installation

– NuGet

– Microsoft Installer (MSI)

• High availability

• ODP.NET, Managed Driver

• Entity Framework 6 and Code First

ODAC 12c Release 3 and Release 4


“Offline” Schema Compare in Visual Studio

Oracle Database Project V2 (SQL Scripts in source control)

Running Database Instance



• Schema Comparison using SQL Scripts in Database Project – New beta feature in Oracle Developer Tools for Visual Studio 12.1.0.2.4

• Compare DBProjv2 against your live DB instance and view differences

• Generate deployment script to make live DB schema equal to DBProjv2

• Automatically update DBProjv2 scripts to equal live DB






“Offline” Schema Compare

• Import your schema into DBProjv2 – Creates a set of standardized SQL scripts, one for each SQL statement

– One CREATE statement per file by convention

– Can be edited – but only the single CREATE statement is honored by Schema Compare

– SQL Scripts can be added or deleted

– Check into source control

– Can “Build” a single Schema create script merging all the SQL scripts into one file

• Schema Compare Dialog updated to include DBProjv2 as source/target

• “Generate Script” and “Update Target” toolbar icons – Can select specific Schema objects to update instead of the entire Schema


See a live demo of Offline Schema Compare

• SQL and PL/SQL Development and Leveraging Oracle Multitenant in Visual Studio

• Thursday – 1:15 PM – 2:00 PM Moscone South – 303


NuGet

• .NET software package manager

– Makes it easier to find, install, configure, deploy, and uninstall assemblies and their dependencies cleanly

– NuGet installs only impact one application; no machine-wide changes

– Easy web deploy to local servers or cloud

• ODAC components supported

– ODP.NET, Managed Driver

– ODP.NET, Managed Driver for Entity Framework 6 and Code First

– Oracle Providers for ASP.NET (using managed ODP.NET)

• Does not include Oracle Developer Tools for Visual Studio

Features and ODAC Package


NuGet

• nuget.org

– Search “Oracle” for relevant packages • Official Oracle ODP.NET, Managed Driver

• Official Oracle ODP.NET, Managed Entity Framework Driver

• Official Oracle Providers for ASP.NET, Managed Driver

• OTN

– Downloadable NuGet packages

– To host within an intranet or install from a local machine

Download and Installation


NuGet

• Most setup steps automatically completed as part installation

• Common remaining steps

– 1. Configure connect descriptor

– 2. Configure connection string

• Note: For Oracle Universal Installer, do not GAC (i.e. machine-wide install) – GAC assemblies override NuGet assemblies with same version (i.e. first four digits)

Configuration


D E M O N S T R A T I O N

NuGet


NuGet

• 1. Open NuGet Package Manager from Visual Studio project

• 2. Select nuget.org and search for Oracle .NET package(s)

– Choose official Oracle .NET package(s) • ODP.NET EF provider automatically includes ODP.NET and EF as dependencies

• ASP.NET providers automatically includes ODP.NET as dependency

• 3. Click Install button and accept license

• 4. Open app/web.config to configure connection string and Oracle connect descriptor

Install Instructions


Microsoft Installer (MSI)

• Native Windows installer

• ODAC components supported

– Oracle Developer Tools for Visual Studio • Visual Studio 2015, 2013, and 2012

– ODP.NET, Managed Driver

– Oracle Providers for ASP.NET (for managed ODP.NET)

• Does not include unmanaged ODP.NET

• Will be available from Visual Studio Gallery and OTN


High Availability

• Planned outages

– Drain connections from pool stopping new connection allocation

• Service Relocation Connection Timeout

– When service becomes unavailable, app encounters connectivity errors

– To avoid connection errors to unavailable service, ODP.NET blocks connection attempts until the service is up or SRCT time limit expires

– Useful for planned outages and service relocations

• Unplanned outages - Transaction Guard (TG)

– Streamlined APIs – Easier to develop with TG

– ODP.NET, Managed Driver supports TG • All unmanaged ODP.NET TG functionality is supported in managed ODP.NET


Planned Outage Scenarios

• DB brought offline as quickly as possible without end user disruptions

• Process

– DB instance being shutdown alerts ODP.NET of impending downtime

– ODP.NET stops creating new connections and closes idle ones

– Existing connections allowed to complete their work

– Connections returned to the pool are closed

– When all connections have drained, instance shuts down

Pool Draining


Unplanned Outage Scenarios

• ODP.NET reliably determines in-flight transaction commit outcome upon a DB failure

– Guarantees accurate knowledge of transaction outcome

– Easier application recovery

• Upon DB failure, ODP.NET OracleException is returned

• Whether transaction is recoverable

• Whether last transaction committed and/or completed

• Once transaction state known, app performs appropriate recovery operations

Transaction Guard


ODP.NET Customer Case Study

• Real time POS integration with over 10,000 sites

• Decrease time to market

• Real-time monitoring and reporting of system performance and health

• Need to run OLTP, batch, and reporting workload concurrently against real time data without impacting user experience

• Support over 2000 real-time transactions per second with SLA of less than 100 ms and 99.95% availability

• Less than 8 hours RPO and RTO

High Availability



• Before using TG and ODP.NET connection pooling:

– Whenever a DB outage occurred, Epsilon required • App restart to remove orphaned connections

• Manually resolving outcomes of in-process transactions

• Upgraded to Oracle Database 12c (12.1.0.2) and ODAC 12c R3

– App now uses TG with ODP.NET connection pooling

• Current planned and unplanned outage experience – No app restarts needed anymore

• ODP.NET pool drains when downed services no longer available

– .NET error handler code resolves in-process transactions by retrieving their status

High Availability




Additional New ODAC 12c R3 and R4 Features

• Managed and unmanaged ODP.NET

– .NET Framework 4.6

– Unified .NET config file format

– Unified tracing format

• Unmanaged ODP.NET

– SQL Translation Framework • Translates vendor-specific SQL to Oracle SQL to ease .NET app migration to Oracle DB

– Managed code for distributed transactions • Requires .NET 4.5.2 or higher

• Managed ODP.NET – Features to be covered in upcoming managed ODP.NET session
