3 Program Agenda SQL and PL/SQL Development Lifecycle Overview Create Development Database - Oracle Multitenant Create Users, Roles and Grant Privileges Creating Schema Objects Visual Studio Source Control Integration PL/SQL and SQL Editing SQL and Performance Tuning PL/SQL Debugging in Visual Studio Schema Compare and Deployment <Insert Picture Here> 3

4 .NET Developer Center on OTN Free downloads of Visual Studio tools, ODP.NET Whitepapers, Sample code Demo Videos Help Forums New Feature request page Latest Oracle on.net News 4

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

6 Oracle Application Development Lifecycle Create Development Database.NET Coding Deploy Tune PL/SQL and SQL Editing/Debug Test Source Control 6

7 Application Development Lifecycle Overview Oracle Developer Tools for Visual Studio Tightly integrated Add-in for Visual Studio 2012 and 2010 ODP.NET ADO.NET compliant data provider Native access to Oracle database Utilize advanced Oracle Database features RAC, performance, security, data types, XML, etc. Both available for free download today 7

8 Create Development Database SQL Plus script Oracle Multitenant 8

9 Multitenant Architecture Components of a Multitenant Container Database (CDB) PDBs Pluggable Databases (PDBs) Root CDB 9

10 Multitenant for Test and Development Clone production, plug into development. Clone/destroy test instances 10

11 PDB Functionality in Server Explorer Pluggable Databases Node New pluggable database: Fast provisioning from the seed Plug: Plug in an XML file and some DBFs Pluggable Databases Node Clone: Fast copy Unplug: Removes PDB from CDB and creates XML manifest Open, Close: Equivalent to Startup and Shutdown Delete: Removes PDB from CDB and deletes files 11

12 Connect to PDBs in Server Explorer Server Explorer connections automatically made to new or cloned pluggable databases TNSNAMES.ORA updated and connection to ADMIN made No Server Explorer connection made when plugging in Need to update TNSNAMES.ORA Connect descriptor same as container, but service_name = pdb name 12

13 Oracle Multitenant with ODP.NET ODP.NET works implicitly with PDBs Connect to the Service_name of the PDB Hostname and port are same as container Requires Oracle Database 12c and ODAC 12c 13

20 D E M O N S T R A T I O N Source Control Integration 20

21 PL/SQL and SQL Editing Oracle PL/SQL Editor database based Collapsible Regions Syntax Coloring Integrated Online Help Supports Debugging Oracle SQL Editor file based 21

22 D E M O N S T R A T I O N SQL and PL/SQL Editors 22

23 Performance Tuning in Visual Studio SQL Tuning Advisor Use when designing new SQL statements Tune ad-hoc SQL statements in Query Window Tune bad SQL found by Oracle Performance Analyzer Use if SQL is performing poorly under load 23

24 SQL Tuning Advisor Requirements ADVISOR privilege Oracle Database license for Oracle Diagnostic Pack Oracle Database license for the Oracle Tuning Pack How to run: Oracle Query Window Tune SQL button Oracle Performance Monitor Tune SQL button 24

25 SQL Tuning Advisor Implement Findings Button Automatically fix the problem for certain finding types View Report Button View more details about how to fix a problem 25

26 Performance Tuning in Visual Studio Oracle Performance Analyzer Detects performance issues in an application s use of the database under load Requirements SYSDBA Oracle Database license for Oracle Diagnostic Pack Can be use during testing Can be also used on production applications 26

27 D E M O N S T R A T I O N SQL Tuning Advisor 27

28 Oracle Performance Analyzer 28

29 Oracle Performance Analyzer Simple to use Run your application Enter amount of time to analyze Press Start to start timer Sufficient database time required to get results View findings and actions Implement recommended actions 29

30 AWR and ADDM Built into the Oracle Database 10g Automatic Workload Repository (AWR) Evolution of statspack Built-in repository Captures performance statistics at regular intervals Automatic Database Diagnostic Monitor (ADDM) Methodically analyses captured AWR stats Generates recommendations 30

31 AWR and ADDM AWR Snapshots A collection of database statistics and performance metrics gathered at a single point in time. Two snapshots make up one analysis time period Oracle Database automatically takes periodic snapshots ADDM Tasks An analysis of Oracle database performance over a period of time Requires two AWR Snapshots to define that time period 31

32 AWR and ADDM in Visual Studio AWR Snapshots New AWR Snapshot Dialog AWR Snapshots Node in Server Explorer ADDM Tasks New ADDM Task Dialog ADDM Tasks Node in Server Explorer ADDM Task results are displayed in Oracle Performance Analyzer 32

33 D E M O N S T R A T I O N Performance Analyzer 33

34 Oracle Performance Analyzer Manual Method, instead of using Timer Run your application Create a Snapshot, via New AWR Snapshot dialog Wait desired time period Create second snapshot Create ADDM Task, via New ADDM Task dialog View Results. If insufficient database time, wait a while and create one more snapshot and another ADDM task 34

35 Oracle Performance Analyzer Manual Method Pros Can close Visual Studio during time period If insufficient database time, you can extend the time period by creating one more snapshot, without having to wait entire duration again Can use database created AWR Snapshots if desired Can elect to monitor all statistics when creating the snapshots 35

36 PL/SQL Debugging - Configuration GRANT debug privileges as SYSDBA 9.2 or later: GRANT DEBUG ANY PROCEDURE TO username, and 10g or later also requires: GRANT DEBUG CONNECT SESSION TO username Set port range and IP in Debugging Options page Tools -> Options->Oracle Developer Tools Compile PL/SQL units for Debug Via menu in PL/SQL editor or in Oracle Explorer 36

37 PL/SQL Debugging - Configuration New requirement in 12c: SYSDBA must grant ACL access on IP Address Port Range Schema name Use new Grant Debugging Privileges dialog Right click on Schema name to be granted both debugging roles and the ACL privileges 37

38 PL/SQL Debugging - Configuration Or issue this PL/SQL as SYSDBA: BEGIN DBMS_NETWORK_ACL_ADMIN.APPEND_HOST_ACE( HOST => ', LOWER_PORT => 65000, UPPER_PORT => 65300, ACE => XS$ACE_TYPE(PRIVILEGE_LIST => XS$NAME_LIST('jdwp'), PRINCIPAL_NAME => 'HR', PRINCIPAL_TYPE => XS_ACL.PTYPE_DB)); END; 38

39 Direct Database Debugging Debug directly inside the database, no application code Step Into from Server Explorer Run Debug from Server Explorer Enter parameters manually Not useful with array parameters or complex types 39

40 Application Debugging Mode Step from.net code into PL/SQL and back from one instance of Visual Studio Useful for client server code (not web apps) Check off Tools -> Oracle Application Debugging ODT automatically starts listener using port in range given in Options page Uncheck "Enable the Visual Studio hosting process" in the.net Project Properties Debug tab 40

41 External Application Debugging Dedicated VS instance for debugging PL/SQL only Use additional VS instance for any.net code (eg ASP.NET app) 10.2 client or later running on ANY platform Set ORA_DEBUG_JDWP in client environment SET ORA_DEBUG_JDWP=host=mymachine;port=4444 Set in web app environment BEFORE connecting Start Listener Tools-> Start Oracle External Application Debugger 41

42 D E M O N S T R A T I O N PL/SQL Debugging 42

43 Deployment Run create scripts Run diff scripts Schema Compare Plug Development PDB into Production CDB Oracle Multitenant 43

44 Using PDBs for Deployment Unplug from development/test environment Plug into production environment 44

45 Schema Compare Tool in Visual Studio New in Oracle Developer Tools for Visual Studio ODAC 12c Oracle Database 10.2 or higher Compare two schemas in the same or different dbs Visually inspect differences using UI Generate a diff script for deployment purposes Reverse schema compare to rollback changes Can compare down to granularity of schema type (eg compare all tables, or all packages, etc) 45

46 Schema Compare View Differences 46

47 Schema Compare Typical Use Case of Visual Studio Developer Development schema identical to production schema Development schema evolves to meet needs of app Use Schema Compare to inspect what has changed Use Schema Compare to generate diff script Deploy diff script with app 47
