Stream Deployment Options

The Deployment tab in the Stream Options dialog box allows you to specify options for deploying the stream.

When you deploy a stream, it's stored in the repository as a file with the extension .str.

Deploying a stream allows you to take advantage of the additional functionality available with IBM® SPSS® Collaboration and Deployment Services, such as multi-user access, automated scoring, model refresh, and Champion Challenger analysis.

Note: The Association Rules, STP, and TCM modeling nodes do not support the Model Evaluation or Champion Challenger steps in IBM SPSS Collaboration and Deployment Services.

From the Deployment tab, you can also preview the stream description that IBM SPSS Modeler creates for the stream. See the topic Stream descriptions for more information.

Deployment type. Choose how you want to deploy the stream. All streams require a designated scoring node before they can be deployed; additional requirements and options depend on the deployment type.

  • <none>. The stream will not be deployed to the repository. All options are disabled except stream description preview.
  • Scoring Only. The stream is deployed to the repository when you click the Store button. Data can be scored using the node that you designate in the Scoring node field.
  • Model Refresh. Same as for Scoring Only but in addition, the model can be updated in the repository using the objects that you designate in the Modeling node and Model nugget fields. Note that automatic model refresh is not supported by default in IBM SPSS Collaboration and Deployment Services, so you must choose this deployment type if you want to use this feature when running a stream from the repository. See Model Refresh for more information.

Scoring node. Select a graph, output or export node to identify the stream branch to be used for scoring the data. While the stream can actually contain any number of valid branches, models, and terminal nodes, one and only one scoring branch must be designated for purposes of deployment. This is the most basic requirement to deploy any stream.

Scoring Parameters. Allows you to specify parameters that can be modified when the scoring branch is run. See Scoring and modeling parameters for more information.

Modeling node. For model refresh, specifies the modeling node used to regenerate or update the model in the repository. Must be a modeling node of the same type as that specified for Model nugget.

Model Build Parameters. Allows you to specify parameters that can be modified when the modeling node is run. See Scoring and modeling parameters for more information.

Model nugget. For model refresh, specifies the model nugget that will be updated or regenerated each time the stream is updated in the repository (typically as part of a scheduled job). The model must be located on the scoring branch. While multiple models may exist on the scoring branch, only one can be designated. Note that when the stream is initially created this may effectively be a placeholder model that is updated or regenerated as new data is available.

Check. Click this button to check whether this is a valid stream for deployment. All streams must have a designated scoring node before they can be deployed. Error messages are displayed if these conditions are not satisfied.

Store. Deploys the stream if it is valid. If not, an error message is displayed. Click the Fix button, correct the error, and try again.
