Generic stage: Stage tab (DataStage)
The Stage tab for the Generic stage enables you to control aspects of the Generic stage.
Double click the stage to open the stage properties panel. The Properties section on the Stage tab lets you specify what the stage does. The Advanced tab allows you to specify how the stage executes.
Properties
The Generic stage has the following properties:
| Category/Property | Values | Default | Mandatory? | Repeats? | Dependent of |
|---|---|---|---|---|---|
| Options/Operator | Orchestrate® operator | N/A | Y | N | N/A |
| Options/Option name | String | N/A | N | Y | N/A |
| Options/Option value | String | N/A | N | N | Option name |
Operator
Specify the name of the Orchestrate operator the stage will call.
Option name
Specify the name of an option the operator requires. This has a dependent property:
- Option Value
The value the option is to be set to.
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.
