Copy stage: Stage tab (DataStage)

Last updated: Mar 12, 2025
Copy stage in DataStage: Stage tab

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

The Stage tab allows you to specify an optional description of the stage. The Properties section lets you specify what the stage does. The Advanced section allows you to specify how the stage executes.

Properties

The Copy stage only has the following property:
Table 1. Properties
Category/Property Values Default Mandatory? Repeats? Dependent of
Options/Force True/False False N N N/A

Force

Set True to specify that IBM® DataStage® should not try to optimize the job by removing a Copy operation where there is one input and one output. Set False by default.

Advanced

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.
