IBM KM404G - IBM InfoSphere Advanced DataStage - Parallel Framework v11.5

Die Unterlagen sind in englischer Sprache, die Kurssprache ist Deutsch.
Zielsetzung: This course is designed to introduce advanced parallel job development techniques in DataStage v11.5. In this course you will develop a deeper understanding of the DataStage architecture, including a deeper understanding of the DataStage development and runtime environments. This will enable you to design parallel jobs that are robust, less subject to errors, reusable, and optimized for better performance.
Zielgruppe: Experienced DataStage developers seeking training in more advanced DataStage job techniques and who seek an understanding of the parallel framework architecture.
Hinweis: Dieses Seminar wird in Zusammenarbeit mit dem offiziellen Partner des IBM Global Training Providers Global Knowledge: Integrata AG oder dem IBM Education Delivery und IBM Sales Partner von Arrow ECS: Fast Lane Institute for Knowledge Transfer GmbH durchgeführt.

Inhalt

1: Introduction to the parallel framework architecture:
Describe the parallel processing architecture
Describe pipeline and partition parallelism
Describe the role of the configuration file
Design a job that creates robust test data
2: Compiling and executing jobs:
Describe the main parts of the configuration file
Describe the compile process and the OSH that the compilation process generates
Describe the role and the main parts of the Score
Describe the job execution process
3: Partitioning and collecting data:
Understand how partitioning works in the Framework
Viewing partitioners in the Score
Selecting partitioning algorithms
Generate sequences of numbers (surrogate keys) in a partitioned, parallel environment
4: Sorting data:
Sort data in the parallel framework
Find inserted sorts in the Score
Reduce the number of inserted sorts
Optimize Fork-Join jobs
Use Sort stages to determine the last row in a group
Describe sort key and partitioner key logic in the parallel framework
5: Buffering in parallel jobs:
Describe how buffering works in parallel jobs
Tune buffers in parallel jobs
Avoid buffer contentions
6: Parallel framework data types:
Describe virtual data sets
Describe schemas
Describe data type mappings and conversions
Describe how external data is processed
Handle nulls
Work with complex data
7: Reusable components:
Create a schema file
Read a sequential file using a schema
Describe Runtime Column Propagation (RCP)
Enable and disable RCP
Create and use shared containers
8: Balanced Optimization:
Enable Balanced Optimization functionality in Designer
Describe the Balanced Optimization workflow
List the different Balanced Optimization options.
Push stage processing to a data source
