System Options
You can specify the preferred language or locale for IBM® SPSS® Modeler by clicking System Options on the Tools > Options menu. Here you can also set the maximum memory usage for SPSS Modeler. Note that changes made in this dialog box will not take effect until you restart SPSS Modeler.
Maximum memory. Select to impose a limit in megabytes on IBM SPSS Modeler's memory usage. On some platforms, SPSS Modeler limits its process size to reduce the toll on computers with limited resources or heavy loads. If you are dealing with large amounts of data, this may cause an "out of memory" error. You can ease memory load by specifying a new threshold.
For example, attempting to display a very large decision tree may cause a memory error; in this case we recommend that you increase the memory to the maximum value of 4096Mb. In cases such as these, where you are likely to be processing very large amounts of data, after you increase the memory allowance shut down SPSS Modeler and start it from a command line to ensure the maximum amount of memory is used when processing your data.
To start from a command line (assuming SPSS Modeler is installed in the default location); in a Command Prompt window, enter the following:
C:\Program Files\IBM\SPSS\Modeler\18\bin\modelerclient.exe" -J-Xss4096M
Use system locale. This option is selected by default and set to English (United States). Deselect to specify another language from the list of available languages and locales.
