Write Range Map stage in DataStage: Stage tab

Write Range Map stage: Stage tab

You can specify aspects of the Write Range Map stage from the Write Range Map stage: Stage tab.

The Advanced section on the Stage tab allows you to specify how the stage executes.


This section allows you to specify the following:

  • Execution Mode. The stage can execute in parallel mode or sequential mode. In parallel mode the input data is processed by the available nodes as specified in the Configuration file, and by any node constraints specified on the Advanced section. In Sequential mode the entire data set is processed by the conductor node.
  • Combinability mode. This is Auto by default, which allows IBM® DataStage® to combine the operators that underlie parallel stages so that they run in the same process if it is sensible for this type of stage.
  • Preserve partitioning. This is Set by default. You can explicitly select Set or Clear. Select Set to request the next stage should attempt to maintain the partitioning.
