Why Migrate to Oracle?What is a migration?

• A Migration is required when you have an application

system that you wish to move to another technology

and/or platform

• For example, you could migrate your application

from:

• Windows to Linux

• Mainframe to UNIX

• Sybase to Oracle

• Visual Basic to Java

• Microsoft SQL Server to Oracle 10g on Linux

• Microsoft Access to Oracle Application Express

Why Migrate to Oracle?Business Drivers for Migration

• Consolidation

• Many Platforms to one

• Hardware and Software Consolidation

• Centralized IT Management

• Reliability/Scalability/Performance

• Core competencies of Oracle

• Key Customer Concerns

• Open Standards

• JAVA, XML, SOAP

Why Migrate to Oracle?Oracle’s Migration Strategy

• Provide cost effective migration solutions to the

Oracle platform

• Migrate entire application(s) & database(s)

• Minimize migration effort by using

• Proven tools & methodology

• Services to support complete project lifecycle

Oracle Migration WorkbenchUsing Workbench Within Migrations

• Capture the source database structure into Source

Model (online/offline)

• Map to Oracle Model

• Create a representation of the structure of the destination

database

• Migrate the source database

• Create the schema online or offline

• Transfer the data online or offline

SQL Developer Migration WorkbenchRationale for Change

• Modernise the UI by integrating with SQL Developer

• Utilise new UI to offer better functionality

• Offer a Migration IDE

• SQL Developer offers longer life cycle for migration

• Use SQL Developer to browse, edit and update the newly migrated

schema objects and schema data.

• Completely new T-SQL Parser

• Extensible framework for new migration tools

• All our migration tools to become SQL Developer Extensions

• Time for a Make Over!

• Original Workbench released in 1998

• Focus had been on expanding the range of 3rd party database

support.

SQL Developer Migration WorkbenchNew Features

• Migration is a 5 step process:

• Connect, Capture, Convert, Generate, Data Move

• UI Provides an Explorer for each step:

• Connect using SQL Developer

• Explore third party databases within SQL Developer

• Capture, Convert via new navigation panes

• Generate – Existing SQL Developer connection

• Take advantage of different ways to migrate:

• Quick Migrate: Provides a simple, assisted UI

• Minimal user interaction.

• Expert Mode: Provides fine grained control

• Select only the objects you wish to migrate

• Spread the workload among a migration team


• Least Privilege Migration

• Migrate objects you own without requiring DBA rights

• Users can migrate any object they can access

• All existing functionality supported

• Offline data migration using generated scripts

• Offline Meta data load using SQL scripts

• Tailored Generation of emulation package

• Only include the referenced functions

• Part of the migrated schema or in its own schema

New Migration Workbench UI


• Migration SDK

• Leverage a strong base of Migration functionality to simplify

extension development

• Develop additional 3rd party database support

• Other enhancements / Additional Migration Tools

• Migration Reports

• Planning and estimation reports

• Migration Detailed & Summary reports

• Ability to develop your own reports

• Uses SQL Developer Reporting capabilities

New Transact-SQL Parser

• Completely Rewritten Parser

• Procedures, Functions, Triggers, Views and Constraints

• Translation Scratch Editor

• Single SQL Statement Migration

• SQL Script Translation

• Import SQL scripts

• Translation Difference Viewer

• Side by side comparison of T-SQL & PL/SQL code

highlighting the SQL Statement conversions

New T-SQL Parser

• Deep Analysis of T-SQL Before Migration

• Keyword Identifier Resolution

• Semantic resolution

• Data Flow Analysis Resolves Cursor Use

• Dependency Analysis Provides

• Correct Parameter Handling

• Generation Order

• Comment Analysis Enhances Comment Positioning

New T-SQL Parser

• Intelligent Translation

• Full Recognition And AST Built Before Translation

• Database Context Aware

• Translation Name Changes

• Column Data Types

• Cleaner More Readable/Maintainable Code
