3 Program Agenda Getting Started Oracle Database 12c Release 2 and ODAC 12.2c Release 1 Oracle Cloud.NET Future Releases

4 Getting Started Oracle.NET

5 Oracle.NET Development Environment Oracle Developer Tools for Visual Studio Visual Studio Database Development App Development Oracle Data Provider for.net Deploy.NET Framework Deploy Oracle Providers for ASP.NET Web or Client/Server Oracle Database Extensions for.net.net Developer Center:

6 Develop on Windows Run Database on any Platform ODT and ODP.NET 12c Visual Studio Windows Windows Linux Solaris Other Oracle DB 12c or 11g

7 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

8 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

9 D E M O N S T R A T I O N Visual Studio Tools and ODP.NET

10 ODP.NET Architecture Managed Layer ODP.NET Oracle.Managed DataAccess.dll ODP.NET Oracle.Data Access.dll Unmanaged Layer ODP.NET Unmanaged DLLs Oracle DB Client Database Oracle Oracle

11 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

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

13 Oracle Database 12.2 and ODAC 12.2 New Features Visual Studio 2017,.NET 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 13

14 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

15 Offline Schema Compare in Visual Studio Running Database Instance Oracle Database Project V2 (SQL Scripts in source control)

16 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

17 Offline Schema Compare in Visual Studio

18 Offline Schema Compare in Visual Studio

19 Connection Open Event Ease of Use 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 19

20 Database Resident Connection Pooling Scalability 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 20

21 Database Resident Connection Pooling TNS Descriptor and Code Sample 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(); } } 21

22 Oracle Multitenant Enhancement Scalability 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 22

23 Oracle Multitenant Enhancement Code Sample using System; using Oracle.DataAccess.Client; class Multitenant { static void Main() { // Create a connection string constr = <connection string>"; OracleConnection con = new OracleConnection(constr); } } // Set the pdb and service names con.pdbname = "US"; con.pdbservicename = "HRDB"; con.open(); 23

24 Oracle Edition-Based Redefinition Enhancement Ease of Development 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() 24

25 Oracle Edition-Based Redefinition Enhancement Code Sample using System; using Oracle.DataAccess.Client; class Editions { static void Main() { // Create a connection string 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(); } } 25

26 Application Continuity High Availability 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

27 Sharding Scalability 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

28 ODP.NET Sharding Code Sample Setting ShardingKey and ShardGroupKey for returning correct shard connection using System; using Oracle.DataAccess.Client; class Sharding { static void Main() { OracleConnection con = new OracleConnection(<Connection String>); //Setting a shard key OracleShardingKey shardingkey = new OracleShardingKey(OracleDbType.Int32, 123); //Setting a second shard key value for a composite key shardingkey.setshardingkey(oracledbtype.varchar2, "gold"); //Creating and setting the super shard key OracleShardingKey supershardingkey = new OracleShardingKey(); supershardingkey.setshardingkey(oracledbtype.int32, 1000); //Setting super sharding key and sharding key on the connection con.setshardingkey(shardingkey, supershardingkey); con.open(); //perform SQL query } }
