Managing Memory

In addition to the Maximum memory setting specified in the System Options dialog box, there are several ways you can optimize memory usage:

• Adjust the Maximum members for nominal fields option in the stream properties dialog box. This option specifies a maximum number of members for nominal fields after which the measurement level of the field becomes Typeless. See the topic Setting general options for streams for more information.
• Force IBM® SPSS® Modeler to free up memory by clicking in the lower right corner of the window where the memory that IBM SPSS Modeler is using and the amount allocated are displayed (xxMB / xxMB). Clicking this region turns it a darker shade, after which memory allocation figures will drop. Once the region returns to its regular color, IBM SPSS Modeler has freed up all the memory possible.
