8 Upcoming ODAC Releases Oracle Database 12c Release 1 High availability Ease of application migration Pluggable Databases ODAC 12c Managed ODP.NET Oracle Schema Compare Production release CY 2013 Soon after Oracle Database 12c Release 1 on Windows release 8

9 Visual Studio 2012 and.net Framework 4.5 9

10 Microsoft Visual Studio 2012 and.net 4.5 Supported by ODAC 11.2 Release 5 Released simultaneously with Microsoft Visual Studio launch Oracle Developer Tools supports Visual Studio 2012 ODP.NET supports.net 4.5 Both 32-bit and x64 certified Both xcopy and OUI versions Oracle official VSIP partner 10

11 Visual Studio Launch Partner 11

12 Schema Compare in Visual Studio 12

13 Schema Compare Upcoming in Oracle Developer Tools for Visual Studio ODAC 12c Compare two schemas in the same or different dbs Visually inspect differences using UI Generate a diff script for deployment purposes Can compare down to granularity of schema type (eg compare all tables, or all packages, etc) 13

14 Schema Compare Typical Use Case of Visual Studio Developer Start with a local instance identical to production db As development of.net app progresses, local db schema evolves to meet needs of app Use SC as needed to inspect what has changed When development is complete, use SC to compare development vs production to generate diff script Deploy diff script with app to bring production db up to required version of schema 14

15 D E M O N S T R A T I O N Schema Compare 15

16 Pluggable Databases 16

17 Database Consolidation Oracle Pluggable Databases Empty PDB SEED CRM ERP DW PRB PDB Root Provision empty PDBs per database that need to be consolidated 17

18 Fast Cloning Pluggable Database Cloning and Snapshots PDB SEED ERP Empty ERP Copy 12 ERP PDB PDB Root Create PDB clones easily within single Container DB (CDB) On clone triggers make it possible to scrub or mask data Clone even faster on file systems supporting copy-onwrite 18

19 Database Consolidation of Existing Databases Logical data migrations for pre-12.1 Databases PDB SEED Empty ERP ERP PDB PDB 11.2 ERP DB Root Data Pump Empty DW DW PDB PDB 10.2 DW DB Replication Empty CRM CRM PDB PDB 11.2 CRM DB Provision empty PDBs per database that need to be consolidated Use datapump or replication to migrate a Database into a PDB 19

20 Database Consolidation of Existing Databases Plug-in 12.1 Standalone Databases PDB SEED Root Upgrade an existing pre-12.1 database to 12.1 Plug-in the database post upgrade into a CDB 12.1 ERP DB 12.1 DW DB 12.1 CRM DB 20

21 PDB Functionality in Visual Studio 21

22 PDB Functionality with ODP.NET ODP.NET works implicitly with PDBs Requires Oracle Database 12c and ODAC 12c 22

23 PDB Functionality in Server Explorer Pluggable Databases Node Menu: Plug, Generate Create Script Pluggable Databases Node Menu: Clone, Unplug, Delete, Status, Generate Create Script 23

24 High Availability 24

25 ODP.NET FAN Uses ONS Oracle Notification Service (ONS) replaces AQ Benefits Faster, more scalable, eliminates firewall issue, supports Active Data Guard, and consolidates publish/subscribe service No code changes required Requires ODP.NET 12c 25

26 Global Data Services Extend RAC services to a global basis Access to FCF, load balancing, and affinity capabilities RAC, Active Data Guard, and GoldenGate can participate Optimizes utilization, HA, and performance No code changes Requires Oracle Database 12c and ODP.NET 12c 26

27 Global Data Services Concepts Sales Service Sales Service Sales Global Service GoldenGate GoldenGate Without GDS With GDS 27

28 Faster and More Graceful Planned Outage Offline DB alerts ODP.NET of impending downtime ODP.NET stops allocating and closes idle connections Connections returned to the pool are closed Benefit DB brought offline as quickly as possible without end user disruptions Set ODP.NET attribute HA Events = true Requires Oracle Database 12c and ODP.NET 12c 28

29 Transaction Guard ODP.NET can determine whether a transaction committed even upon some DB failure Benefit Ensure transaction commits at most one time No duplicates Transaction outcome can be queried by the application OracleConnection properties return transaction id and status OracleLogicalTransactionStatus class Requires Oracle Database 12c and ODP.NET 12c 29

30 Transaction Guard 1. Request 4. Guaranteed Outcome 2. Calls 3. Enforce Outcome Oracle Database 12c Release 1 30

31 Recoverable Error Detection and Recovery After DB error, ODP.NET determines if failed transaction is recoverable or not Returns error message if operation cannot be retried ODP.NET OracleException property indicates if transaction recoverable and can be retried Benefit Easier to determine next step in transaction recovery process Requires Oracle Database 12c and ODP.NET 12c 31

32 Connection Timeout Error Improvement Returns specific error when no connection allocation possible due to max pool size limit Previously, error was vague Can distinguish CP errors from other client and server errors Benefit Easier to identify and resolve CP-related error No code changes to use If already capturing error messages Requires ODP.NET 12c 32

33 Ease of Application Migration 33

34 Implicit REF CURSOR (RC) ODP.NET retrieves result set without explicit RC declaration nor RC metadata in.net config Can retrieve multiple implicit RCs ExecuteNonQuery Returns array of RCs ExecuteReader Returns DataReader, each accessible via calling NextResult Benefit Simplifies retrieving result sets from PL/SQL Entity Framework will still require result set metadata in.net config 34

35 Boolean Data Type ODP.NET OracleBoolean data type Can be used with PL/SQL Booleans Benefit Eases parameter binding Stored procedures Entity Framework Function Imports 35

36 Identity Column DB automatically generates auto-incrementing value as needed Supports ANSI s IDENTITY keyword Benefit Easier to set up auto incrementing values, such as for primary keys Integrated with ODT and ODP.NET E.g. ODT: Create table with auto-incrementing Identity column E.g. ODP.NET: Add row without explicitly providing identity value 36

37 Large VARCHAR2, NVARCHAR2, and RAW ODP.NET VARCHAR2, NVARCHAR2, and RAW data types now can be up to 32 KB in size Benefit Remain with fundamental data types even with larger data No need to modify schema or use more advanced type 37

38 Return Row Count Per Array DML Iteration ODP.NET returns number of rows affected for each input value, not just the total number of rows affected New OracleCommand.ArrayBindRowCount property Returns number of affected rows for each executed array bound DML iteration Benefit Provides more info on DML correctness and efficiency 38

39 Managed ODP.NET 39

40 Managed ODP.NET vs. Unmanaged ODP.NET Advantages One assembly for both 32-bit and x64 Easier side by side deployment Deploy smaller and fewer binaries Before: 150 MB After: Less than 10 MB Easier patching process Fully integrated with Code Access Security 40

41 Current ODP.NET Architecture Managed and Unmanaged Managed Unmanaged Database ODP.NET Oracle.Data Access.dll ODP.NET Unmanaged DLLs OCI NET Oracle 41

42 Forthcoming ODP.NET Architecture Fully Managed Managed Database ODP.NET Oracle.Managed DataAccess.dll Oracle 42

43 Managed ODP.NET 100% managed provider Assembly Oracle.ManagedDataAccess.dll No other Oracle Client files required Unless using distributed transactions Namespaces Oracle.ManagedDataAccess.Client Oracle.ManagedDataAccess.Types 43

44 Managed ODP.NET Same assembly for either 32-bit and x64 Windows Can be deployed side by side With unmanaged ODP.NET With managed ODP.NET Installable via OUI and xcopy Beta currently downloadable from OTN 44

45 Managed ODP.NET Certified with.net Framework 4 and higher only Visual Studio 2010 and 2012 Supports Oracle DB 10.2 and higher 45

46 D E M O N S T R A T I O N Hello (Managed) World 46

47 Managed ODP.NET Features Standard ADO.NET provider objects, methods, and properties Visual Studio drag and drop code generation Oracle Developer Tools for Visual Studio Full SQL or PL/SQL Connection pooling features Min, Max, Timeout, Lifetime, Increment, Decrement Automatic RAC Load Balancing and Fast Connection Failover Performance counters 47

48 Managed ODP.NET Features Entity Framework Native Oracle data types REF Cursor, LOBs, Date, String, Decimal, Binary, TimeStamp, etc. SecureFiles/LOB and LONG retrieval APIs Oracle data types in DataSet Multiple Active Result Sets Self-tuning 48

49 Managed ODP.NET Features Security and auditing Proxy authentication Operating system authentication End-to-end tracing with Client Id, Action, and Module New features ONS Connection pool timeout error 49

50 Distributed Transactions Requires an additional managed DLL (for now) Oracle.ManagedDataAccessDTC.dll If not using distributed transactions, no need to deploy additional DLL No direct reference to DLL directly Implicitly loaded Two versions with same name: 32-bit and x64 Still must match 32-bit or 64-bit COM calls 50

51 Managed ODP.NET vs. Unmanaged ODP.NET Features Unavailable in First Release User defined types Oracle-specific XML features and data types Advanced Queuing Client Result Cache BulkCopy Transaction Guard 51

52 Managed ODP.NET Deployment Concepts Option 1: single configuration file deployment.net config file contains TNS and sqlnet.ora settings i.e. Machine.config, web.config, app.config Option 2: multi-file configuration.net config file Tnsnames.ora and sqlnet.ora Option 3: no configuration files Store connect info in Data Source attribute 52

53 D E M O N S T R A T I O N Deploying Managed ODP.NET 53

54 Managed ODP.NET Deployment Concepts.NET config file Similar settings as unmanaged plus TNS and sqlnet.ora settings Managed - <oracle.manageddataaccess.client> Unmanaged - <oracle.dataaccess.client> Tnsnames.ora and Sqlnet.ora Same attribute settings Most, but not all attributes are available 54

55 Unmanaged to Managed Migration Application migration process 1. Replace Oracle.ManagedDataAccess.dll reference to project 2. Modify namespace(s) to Managed ODP.NET 3. Change.NET config settings for Managed ODP.NET Include sqlnet.ora settings Managed ODP.NET APIs same as ODP.NET APIs Initially, Managed ODP.NET will not support all ODP.NET features Plan is eventual feature parity 55

56 D E M O N S T R A T I O N Porting to Managed ODP.NET 56

57 Managed ODP.NET Release Timeline Public beta 1 on OTN Release more public betas Depends on customer feedback and additional features Production release CY
