Page Setting Assistant for Maps (dtxpage)

The Page Setting Assistant for Maps application is used to calculate suggested settings for memory page size and count for work files used in maps. It is started by using the dtxpage utility command. The .mmc file is a required parameter and is the file name of the map for which the calculation is being performed.

The application will run iterations of the specified map and therefore you should expect that the overall run time will be longer than a typical run.

See the Utility Commands documentation for information about how to use the dtxpage utility command from the command line.

The Page Setting Assistant for Maps application invoked by the dtxpage utility command is an important tool to assist you in improving the performance of your maps and achieving your performance goals.
