4 Oracle s.net Products Oracle Developer Tools for Visual Studio Tightly integrated Add-in for Visual Studio 2015, 2013, 2012 Oracle Data Provider for.net (ODP.NET) ADO.NET compliant data provider Utilize advanced Oracle Database features RAC, performance, security, data types, XML, etc. Both available for free download:

5 PL/SQL Editing and Debugging

6 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

7 Oracle PL/SQL Debugging Architecture Oracle Developer Tools for Visual Studio Visual Studio Environment VS sends requests to Oracle over TCP/IP connection: Step Into Please What are the local variable values? Set Breakpoint here Connect user/pass When connect to Oracle we pass: ORA_DEBUG_JDWP= host=hostname;port=portnum Oracle 10.2 or later PL/SQL Debugging Engine Does all the work of debugging

8 PL/SQL Debugging Configuration Can be tricky the first time since so many steps Check out the PL/SQL Debugging Chapter in ODT online doc Debugging Setup Checklist Work through the Oracle by Example demo:

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

10 PL/SQL Debugging Configuration GRANT debug privileges as SYSDBA GRANT DEBUG ANY PROCEDURE TO username 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 Server Explorer Server Explorer Icons change color to remind you to recompile later

11 PL/SQL Debugging Configuration New requirement in Oracle Database 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

12 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;

13 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

14 D E M O N S T R A T I O N Direct Debugging

15 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

16 D E M O N S T R A T I O N Direct and App Debugging

17 External Application Debugging Dedicated VS instance for debugging PL/SQL only Use additional VS instance for any.net code (eg ASP.NET app) PL/SQL called by 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

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

19 Using DBMS_DEBUG_JDWP Package Allows you to pick and choose when debugging is turned on Good solution when PL/SQL packaged procedure is called often but you only are interested in debugging specific cases Enable External Application Debugging Provide port number and IP address

20 Using DBMS_DEBUG_JDWP Package Add calls to these PL/SQL Procedures to your SP: DBMS_DEBUG_JDWP.CONNECT_TCP(HOST VARCHAR2, PORT VARCHAR2) DBMS_DEBUG_JDWP.DISCONNECT Compile Debug Set Breakpoint Enable External Application Debugging Call SP from external application or middle tier

21 Schema Compare and Script Management

22 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

23 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

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

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

26 Offline Schema Compare in Visual Studio Schema Comparison using SQL Scripts in Database Project New beta feature in Oracle Developer Tools for Visual Studio 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

27 Offline Schema Compare Import your schema into DBProjv2 Creates a set of standardized SQL scripts, one for each SQL statement Only one SQL statement (CREATE) 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

29 Oracle Multitenant and Visual Studio

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

31 Multitenant for Test and Development Clone Test system, plug into Development. Clone/destroy test instances

32 Multitenant is great for developers Very rapid cloning and creating database About as long as copying the database files (minutes) Using DBCA to create a database takes a long time Rapid sharing with other devs for testing Unplugged PDBs are an XML file and several DBF files Zip these up and share with other developers who can plug them in and be using them in minutes

33 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 Database Nodes 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

34 PDB Functionality 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 create TNSNAMES.ORA aliases or use EZ Connect Connect info for PDB is the same as container (host, port, etc) EXCEPT: service_name = pdb name

35 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

36 Using PDBs for Deployment Unplug from development/test environment Plug into deployment environment
