Oracle Developer Tools for Visual Studio

• “Add-in” for Visual Studio– Works with VS 2015 and VS 2017

– Download from OTN (MSI or Oracle Installer)

• Tight integration with Visual Studio data features– Server Explorer

– Table Adapter Configuration Wizard

– Entity Designer

• Oracle specific features– Oracle Designers (Table, View, Stored Proc, AQ, etc)

– PL/SQL Debugging

– Offline Database Project, Schema Compare… and much more


ODP.NET Overview

• Implements standard ADO.NET– ADO.NET: Microsoft’s standard for data access from .NET code

• Extended to provide native access to Oracle Database

– Utilize advanced Oracle Database features

– E.g. RAC, performance, security, data types, XML, etc.

• Download– Nuget

– OTN: MSI installer

– OTN: Oracle Installer

– OTN: Xcopy install

Key ODP.NET Features

• Connection pooling and performance counters– Runtime Load Balancing, Fast Connection Failover: RAC and GDS

– Transaction Guard

– Planned Outage

• Native Oracle data types

– REF Cursors, LOBs, XMLType, UDTs, arrays, etc.

• Performance

– Caching

– FetchSize and RowSize, InitialLOBFetchsize

• Entity Framework


Oracle Database 12c Release 2 and ODAC 12.2c Release 1Oracle .NET


Oracle Database 12.2 and ODAC 12.2

• Visual Studio 2017, .NET 4.6.2 and 4.7, and Entity Framework 6.2

• Schema Compare

• ODP.NET Database Resident Connection Pooling (DRCP)

• Oracle Multitenant pooling across PDBs

• Application Continuity

• Sharding

• Connection Open event

• Oracle Edition-Based Redefinition pooling across editions

New Features

13


“Offline” Schema Compare in Visual Studio

• Schema Comparison using SQL Scripts in “Database Project Version 2”

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

– One CREATE statement per file by convention

– Check the scripts into source control

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



Oracle Database Project V2(SQL Scripts in source control)

Running Database Instance


“Offline” Schema Compare

• Compare DB Project v2 against your live DB instance and view diffs

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

• Automatically update DB Project v2 scripts to equal live DB


Connection Open Event

• Developers provide custom code, which is executed prior to dispensing connection

• Benefit: centralized place for initialization/customization before using connection

– E.g. set session settings and tags

Ease of Use

19


Database Resident Connection Pooling

• DRCP pools connections at DB server level

– Pools "dedicated" servers

– Pooled server = equivalent of combined server foreground process and DB session

• Supports large numbers of client connections and across middle-tiers

• Enable DRCP using “(SERVER=POOLED)“ in TNS descriptor– No ODP.NET code changes required

• New OracleConnection properties (optional)

– string DRCPConnectionClass; – share one server pool across multiple mid-tier pools

– bool DRCPConnectionPurity; – returns a new DRCP connection

Scalability

20


Database Resident Connection PoolingTNS Descriptor and Code Sample

21

oracle = (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=myserver)(PORT=5521)) (CONNECT_DATA=(SERVICE_NAME=db.company.com)(SERVER=POOLED)))

----------

using System;using Oracle.DataAccess.Client;

class DRCP{

static void Main(){

string constr = “<connection string>";OracleConnection con = new OracleConnection(constr);con.DRCPConnectionClass = "classA";con.Open();

}}


Oracle Multitenant Enhancement

• Support for multiple PDBs in the same pool

– No longer need separate pool for each PDB

• Switch between PDBs in the same pool

– Requires PDBs to be in same CDB and the same user

• Switching requires closing the connection to the old PDB and opening a connection to the new PDB

• Set OracleConnection PDBName and PDBServiceName properties to identify PDB connection from pool to use

Scalability

22


Oracle Multitenant EnhancementCode Sample

23


class Multitenant{

static void Main(){

// Create a connectionstring constr = “<connection string>";OracleConnection con = new OracleConnection(constr);

// Set the pdb and service namescon.PDBName = "US";con.PDBServiceName = "HRDB";con.Open();

}}


Oracle Edition-Based Redefinition Enhancement

• Connections to multiple editions can now co-exist in the same pool

• DB Edition name can now be set at the OracleConnection level

• Switch between Editions in the same application and/or pool

– Requires same user if switching editions in same pool

• Switching requires closing the connection to the old Edition and opening a connection to the new Edition

• Set OracleConnection.DatabaseEditionName property before Open()

Ease of Development

24


Oracle Edition-Based Redefinition EnhancementCode Sample

25


class Editions{

static void Main(){

// Create a connectionstring constr = “<connection string>”;OracleConnection con = new OracleConnection(constr);// Set the edition name before Open()con.DatabaseEditionName = "EditionX";con.Open();con.Close();con.DatabaseEditionName = "EditionY";con.Open();

}}


Application Continuity

• OpenWorld session: Best Practices for High Availability: .NET and Oracle Database

• Wednesday, Oct 04, 3:30 p.m. - 4:15 p.m.

• Moscone West - Room 3010

High Availability

26


Sharding

• Type of DB partitioning that separates very large databases the into smaller, faster, more easily managed shards

• Data dependent routing added to ODP.NET to access shard data

• ODP.NET and sharding typical use

1. App specifies sharding key and/or super sharding key before establishing connection

2. ODP.NET connects to specific sharded instance that holds the data associated with the specified keys

3. Data is retrieved

Scalability


ODP.NET Sharding Code SampleSetting ShardingKey and ShardGroupKey for returning correct shard connection


class Sharding{

static void Main(){OracleConnection con = new OracleConnection(<Connection String>);//Setting a shard keyOracleShardingKey shardingKey = new OracleShardingKey(OracleDbType.Int32, 123);//Setting a second shard key value for a composite keyshardingKey.SetShardingKey(OracleDbType.Varchar2, "gold");//Creating and setting the super shard keyOracleShardingKey superShardingKey = new OracleShardingKey();superShardingKey.SetShardingKey(OracleDbType.Int32, 1000); //Setting super sharding key and sharding key on the connectioncon.SetShardingKey(shardingKey, superShardingKey);con.Open();//perform SQL query
