Connection Manager

Create and test connections with a wizard Store often-used connections Import and export connections Reuse connections throughout lifecycle

– Database, PL/SQL Development– Application Development– Deployment

Additional connection types– Application Server, WebDAV Server, SOAP Server,

Oracle9i SCM Server, UDDI Registry

Browsing the Database

View schema objects from the Navigator– Tables (Indexes, Columns, Constraints, Data)– Views– Synonyms– PL/SQL subprograms– Oracle Objects– Materialized Views (Snapshots)– Java Resources

User-defined filters at all levels

Creating Database Objects

Create schema objects– PL/SQL subprograms– Tables– Views– Triggers

SQL Worksheet

Execute any valid SQL statement Browse query results Access previous statements from SQL History Fetch rows incrementally

Tuning SQL Statements

Database and SQL Development Schema Modeling and Offline Editing PL/SQL Development and Debugging Questions and Answers

Schema Modeling

“Design-capture” existing schema objects Visually design tables

and relationships Generate DDL

from diagram– SQL File– Directly to database– Reconcile

with database

Offline Tables

Import objects from an existing database Create and edit table definitions while

disconnected Generate DDL to create or alter tables Reconcile changes with database

Schema Modeling

Agenda

Database and SQL Development Schema Modeling and Offline Editing PL/SQL Development and Debugging Questions and Answers

Editing and Compiling PL/SQL

Comprehensive editor features– Bookmarks– Macros– Code Templates– Search and Replace – Syntax Highlighting – Etc

PL/SQL Code Insight Synchronized Structure window Errors reported in Log window

Running PL/SQL

Run Procedures, Functions, and Packages– DBMS_OUTPUT– Function return values– OUT parameters

Run PL/SQL dialog – Specify run target– Shows parameter information– Generates editable PL/SQL block for populating

parameters

Debugging PL/SQL

Supported with Oracle8i and later– Uses JDWP implementation starting with

Oracle9i Release 2

Control program execution– Step Into, Step Over, Run to Cursor, etc

Inspect and modify variables– Tooltips in Code Editor

Configure breakpoint conditions

PL/SQL Debugging Requirements

Compiled with debug information– JDeveloper “Database Connections” preferences panel– ALTER SESSION SET PLSQL_DEBUG = TRUE– ALTER <PROG_UNIT> COMPILE DEBUG

Oracle8i and Oracle9i specifics– CREATE ANY PROCEDURE (debugging other schemas)

Oracle9i Release 2 specifics– DEBUG ANY PROCEDURE

DEBUG CONNECT SESSION– Compiled in Interpreted (not Native) mode

Additional PL/SQL Debugger Features with Oracle 9.2

Debug Java stored procedures Seamless debugging between server-side

Java and PL/SQL Inspect elements of PL/SQL Collections

(Tables, Records, etc) Remotely debug PL/SQL calls from any client

Remotely Debugging PL/SQL

Client Application

1: Listen1: Listen

2: Attach2: Attach

3: Execute3: Execute

Database Session

JDeveloper

Remotely Debugging PL/SQL:Explicit Calls

1. Start the debugger listener in JDeveloper (Listen for JPDA)

2. Modify the client code to attach to the debugger listener from the database session:DBMS_DEBUG_JDWP.CONNECT_TCP (‘host’, port);

3. Initiate procedure call from the same database session, for example:EXEC my_procedure;

4. Modify the client code to terminate the connection with the debug listener:DBMS_DEBUG_JDWP.DISCONNECT_TCP();

Remotely Debugging PL/SQL:Implicit Calls

Two-tier OCI applications– Set environment variable

set ora_debug_jdwp = host12.acme.com;port=4040

– OCI layer transparently calls the server-side PL/SQL to connect with the debugger listener

Web mod_plsql applications– Create a UI form to set a cookie in the browser– Pass the hostname and port to owa_debug package– owa_debug transparently calls the server-side PL/SQL to

connect with the debugger listener for each subsequent page requested by that browser
