Man in the Mirror

Goodbye Old Friend

Migrations are Hard

Add Value

Have a Mission Statement

Mission Statement
13
Any task undertaken to migrate content from OWB to ODI
will add immediate value to our BI stakeholders.

ODI 12c: Overview
14
Flow-Based Declarative
Design with Component-Based
Development
New Mappings replace
interfaces and allow multi-step
design patterns
Reusable Mappings and
Datasets for Declarative Design
similar to 11g

ODI 12c: Overview
15
Components Provide
Multi-Step Process
Data Lineage built into
the Mapping Editor

ODI 12c: Overview
16
Warehouse Builder-like
Components including
Pivot/Unpivot, Join,
Expression, Set, etc.

ODI 12c: Overview
17
Component-Style KM’s
encapsulate modular, reusable
pieces of logic specific to
particular Components

ODI 12c: Overview
18

Installing ODI 12c: Enterprise Installation
19
Enterprise Installation
includes Fusion Middleware
and supports Standalone
Colocated Agents
Handles configuration of the
Master and Work repositories
and other FMW tables (Work
Tables)
JEE Agents can utilize
Weblogic Coherence for high
availability

20
Warning: FMW
Needs to be installed
for JEE Agents

21
We get all this
cool stuff!

22

Repository Creation Utility
23
Recent Oracle Database
versions, including 11gR2 and
12c, as well as DB2 and SQL
Server
Master Repository contains
Topology information, Work
Repository contains
development information
Creates Fusion Middleware
tables, including Fusion Work
Tables

Agents
24

Agents
25
ODI Agents execute load
processes, including compiled
Load Plans and Scenarios
Somewhat comparable to the
OWB Control Center
(much, much better)
Deployed as JEE Agents or
Standalone Agents

Domain Configuration
26
Use built-in FMW and WLS
functionality to “harden” our
ODI Agents
Our JEE-deployed ODI Agent
is comparable to an ETL Server
Utilizing Coherence gives us
performance increases in
certain circumstances, fault
tolerance, etc.

27
Domain
Configuration
Templates make it
easy to mix and
match deployed
functionality to
our domain

28
Service Table
Schema (STB)
stores relevant
information from
our install to
feed the
templates

29
In the end, we
have a WLS
Domain complete
with Admin
Server and
Managed Server

30

OWB Runtime Integration

OWB Runtime Integration
32
Execute OWB processes as
standard ODI processes,
including Mappings and
Process Flows
Full execution from OWB
Control Center captured in
standard ODI audit tables
Orchestrate our loads
wherever we want: ODI Load
Plans or OWB Process Flows

OWB Runtime Integration Topology
33
Data Server
configured with
OWB Workspace
Owner

34
JDBC
Configuration to
the OWB
Workspace

35
Configure the
Workspace Owner
as the Physical
Schema

36
Setting a Logical
Schema to
abstract the
Physical Schema
and Data Server

37

OWB Runtime Integration Execution
38
Use the ODI Package
Editor and the new
OdiStartOwbJob tool
We can execute
Mappings or
Process Flows
OdiStartOwbJob "-WORKSPACE=OWBREP" "-LOCATION=OWF_MGR"
"-OBJECT_NAME=SBATCH/MAIN_LOAD" "-OBJECT_TYPE=PROCESSFLOW"

Migration Utility
42
Supports 11.2.0.4 of
Warehouse Builder with Patch
17830453
Apply Patch 17053768 to
Data Integrator if not already
included in release
Command-line utility to
perform the OWB to ODI
Migration

Migration Utility: Run Modes
FAST_CHECK
Performs a read-only check of the OWB repository and
reports back the items than can and cannot be
migrated.
DRY_RUN
Performs a migration to ODI using the ODI 12c SDK, but
does not perform a commit at the end of the process.
RUN (Default)
Executes the migration and commits migrated objects
to the target ODI 12c repository.

Oracle Warehouse Builder (Our Old Friend)

Oracle Warehouse Builder (Our Old Friend)

Wildly Successful
•Flow-based design
•High-performing code (EL-T)
•Ships with Database 10g and 11g
•PL/SQL Code Generation
•Freemium model
Deprecated
•Certified (not shipped) with
Database 12c
•In maintenance mode
Limited Integration
Capabilities

Oracle Data Integrator 12c

Oracle Data Integrator 12c
52
Best of both worlds!
•Now with flow-based design
•High-performing code (EL-T)
•Knowledge Module architecture
•Enterprise Manager integration
•Fusion Middleware integration
Is there value in changing?
•“Our organization has a major
investment in OWB”
•“Our mappings and process
flows just work”

If Only There Was a Way to…
53

If Only There Was a Way to…
54
Maintain investment in OWB
•Continue to execute legacy code
•Only port our code when it
presents value to do so
Blaze new trails with ODI 12c
• Fantastic new features are dying
to be used
• The Knowledge Module (KM)
architecture pays huge dividends
Deploy a coherent strategy
•Shouldn’t feel like two tools

It’s not an easy choice
