Head stage: Advanced tab

Head stage: Advanced tab

This tab allows you to specify options.

This tab 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 tab. In Sequential mode the entire data set is processed by the conductor node.
  • Combinability mode. This is Auto by default, which allows InfoSphere® 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 Propagate by default. It adopts Set or Clear from the previous stage. You can explicitly select Set or Clear. Select Set to request that next stage in the job should attempt to maintain the partitioning.
