Encode stage: Stage tab (DataStage)

Encode stage: Stage tab (DataStage)

The Encode Stage tab enables you to control aspects of the Encode stage.

On the Stage tab, the Properties section lets you specify what the stage does. The Advanced section allows you to specify how the stage executes.


The Encode stage has the following property:
Table 1. Properties
Category/Property Values Default Mandatory? Repeats? Dependent of
Options/Command Line Command Line N/A Y N N/A

Command line

Specifies the command line used for encoding the data set. The command line must configure the UNIX command to accept input from standard input and write its results to standard output. The command must be located in your search path and be accessible by every processing node on which the Encode 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.
