Storing and Deploying Repository Objects
Streams created in IBM® SPSS® M odeler can be stored in the repository just as they are, as files
with the extension .str. In this way, a single stream can be accessed by multiple users throughout
the enterprise. For more information, see the topic Storing Objects in the Repository on p. 164.
It is also possible to deploy a stream in the repository. A deployed stream is stored as a file wi th
additional metadata. A de ployed stream can take full advantage of the enterprise - level feat
ures
of IBM SPSS Collaboration and Deployment Services, such as automated scoring and model
refresh. For example, a model can be automatically updated at regularly-scheduled intervals
as new data becomes available. Alternatively, a set of streams can be deployed for Champion
Challenger analysis, in which streams are compared to determine which one contains the most
effective predi ctive model.
You can deploy a stream in one of two ways: as a stream (with the extension .str), or as a scenario
(with the extension .scn). Deployment a s a stream enables the stream to be used by the thin-client
applicat ion IBM® SPSS® Modeler Advantage . For more information, see the topic Opening a
Stream in IBM SPSS Modeler Advantage in Chapter 10 on p. 195. Deployment as a scenario
enables the stream to be used by Predictive Applic ations vers ion 5, the predecessor of IBM
SPSS Mod eler Advantage.
For more information, see Stream Deploy ment Options on p. 185.
Requirements for Streams Deployed as Scenarios
To ensure consistent access t o enterprise data, strea ms deployed as scenarios must be access ed
through the Enterprise View component of IBM® SPSS® Collaboration and Deployment
Services. This means that in SPSS Modeler, there must be at least one Enterprise View source
node within each designated scoring or modeling branch in the strea m.
To use the Enterprise View node, IBM SPSS Collabor ation and Deploym ent Services
must be in stalled, configured and accessible from your site, with an Enterprise View,
Applica tion Views, and Data Provider Definitions (DPDs) already defined. For
more information, contact your lo cal administrator, or see the corporate website at
http://www.ibm.com/software/analytics/spss/products/deployment/cds/.
A DPD is d efined against a particular ODBC data source. To use a DPD from SPSS Modeler,
you must have an ODB C data source defined on the SPSS Model er server host that has the
same name and that connects to the same data store as the one referenc ed in the DPD.
In addition, the IBM® SPSS® Collaboration and Deployme nt Services Enterp r ise View
Driver must be installed on each computer used to modify or run the stream. For Windows,
simply install the driver on the computer where SPSS Modeler or SPSS Modeler Server is
installe d, and no further configuration of the driver is needed. On UNIX, a reference to the
pev.sh script must be added to the startup script. Contact your loca l administr ator for details
on installing the IBM SPSS Collaboration and Deploy ment Services Enterprise View D r iver.
