This manual explains how to install Oracle Data Mining and prepare the database for mining activities.

The preface contains these topics:


This guide is intended primarily for users who want to install, configure, and use Oracle Data Mining on Microsoft Windows for data mining exercises and demonstrations.

Note for DBAs:

DBAs managing production databases that support Oracle Data Mining should follow standard administrative practices as described in the Oracle Database Administrator's Guide.

Building data mining models and batch scoring of mining models tend to put a DSS-like workload on the system, and single-row scoring tends to put an OLTP-like workload on the system.

Documentation Accessibility

Our goal is to make Oracle products, services, and supporting documentation accessible to all users, including users that are disabled. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Accessibility standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers. For more information, visit the Oracle Accessibility Program Web site at

Accessibility of Code Examples in Documentation

Screen readers may not always correctly read the code examples in this document. The conventions for writing code require that closing braces should appear on an otherwise empty line; however, some screen readers may not always read a line of text that consists solely of a bracket or brace.

Accessibility of Links to External Web Sites in Documentation

This documentation may contain links to Web sites of other companies or organizations that Oracle does not own or control. Oracle neither evaluates nor makes any representations regarding the accessibility of these Web sites.

Deaf/Hard of Hearing Access to Oracle Support Services

To reach Oracle Support Services, use a telecommunications relay service (TRS) to call Oracle Support at 1.800.223.1711. An Oracle Support Services engineer will handle technical issues and provide customer support according to the Oracle service request process. Information about TRS is available at, and a list of phone numbers is available at

Where to Find Database Tuning Documentation

The Oracle Data Mining documentation set does not address the topic of database tuning for data mining. The Oracle Database Performance Tuning Guide is the best source of information for tuning Oracle Database (including when the goal is to invoke mining build/score operations).

The memory tuning parameters PGA_AGGREGATE_TARGET and SGA_TARGET can easily have the most impact on data mining. The correct setting of PGA is very important for model building routines, as well as complex queries and batch scoring. From a Data Mining perspective, the SGA is generally less of a concern, except that real-time scoring is enabled by having the model loaded into the shared cursor in the SGA, so this still should be sized accordingly.

In addition, if parallel execution is desired, then there are INIT.ORA parameters that control this functionality.
