Informatica PowerCenter 10.x Foundation | Advanced Boot Camp for Developers

Course Objectives

NOTE: The Informatica Training Series is independent-format training that can be tuned and adjusted to best meet your needs. Our materials are flexible, comprehensive, and are always instructed by a senior instructor with a deep understanding of Informatica and its most current features, benefits and functionality in a wide array of uses. This is not Official Informatica Training.

Course Prerequisites

Intermediate and beyond for experienced ETL Developers with previous PowerCenter experience.

Course Agenda

1. Getting Started

• Course objectives

2. Mapping Techniques – local variables

• Using local variables: self and forward references

3. Mapping Techniques – Pivoting data

• Using the Normalizer transformation (level of occurs, generated keys, examples)
• Normalizing flat file outputs
• Denormalizing with unconnected Lookups
• Denormalizing with the Aggregator (conditional clause and local variables)

4. Mapping techniques  - self-joins

• Using a Joiner with the sorted input property

5. Mapping Techniques – Lookup Transformation

• Using dynamic caching
• Pipeline lookups
• Lab: Self-join, Dynamic Lookup and Denormalizing

6. Mapping Techniques – Surrogate Keys

• Using the Sequence generator transformation
• Using a trigger, GUID or update overrides

7. Mapping Techniques - other

• Calling stored procedures
• Transaction Control transformation and commit points
• Transaction scope

8. Advanced Parameter usage

• Sharing mapping parameters between sessions

Day Two

9. Mapping Templates

• Slowly changing dimension updates (type 1, 2, 3 and mixed)
• Lab: dimensional updates
• Data validation and error trapping
• Comparing the contents of two tables and extracting differences
• Building parameter files
• Lab: parameter files

10. Performance Tuning

• Understanding PowerCenter’s architecture
• Getting baseline numbers
• Using performance counters
• Identifying bottlenecks
• Tuning the target and source components
• Tuning blocking transformations
• Tuning Lookup transformations
• Tuning the session, caches and memory
• Using session partitioning
• Tuning the workflow
• Running multiple instances of the same workflow
• Running a session or a workflow on a grid
• Lab: session partitioning
• Using PushDown optimization (optional)

Course Materials

Each student will receive a Student Guide with course notes, code samples, software tutorials, diagrams and related reference materials and links (as applicable). Our courses also include step by step hands-on lab instructions and and solutions, clearly illustrated for users to complete hands-on work in class, and to revisit to review or refresh skills at any time. Students will also receive the project files (or code, if applicable) and solutions required for the hands-on work.
