Course Details
The IBM InfoSphere Advanced DataStage - Parallel Framework v11.5 course is a 3-day course that is designed to introduce students to advanced parallel job development techniques in IBM DataStage v11.5. During this course, students will develop a deeper understanding of the DataStage architecture, including a strong foundation of the DataStage development and runtime environments. This course will enable students to design parallel jobs that are robust, less subject to errors, reusable and optimized for better performance.
Topics covered in the course include:
- Designing a job that creates robust test data
- Describing the job execution process
- Generating sequences of numbers (surrogate keys) in a partitioned, parallel environment
- Describing sort key and partitioner key logic in the parallel framework
- Working with complex data
- Describing the Balanced Optimization workflow
Target Student:
Experienced DataStage developers seeking training in more advanced DataStage job techniques and who seek an understanding of the parallel framework architecture.
Prerequisites:
IBM InfoSphere DataStage Essentials course or equivalent and at least one year of experience developing parallel jobs using DataStage.

Testimonials
This was the class I needed.
The instructor Jeff took his time and made sure we understood each topic before moving to the next. He answered all of our questions, and I don't know about the rest of the students, but was very pleased with this experience.
I finally understand how to use Excel.

Great class!
We were able to cover a lot of information in one day without getting overwhelmed.
