RAM versus Heap Memory

When evaluating memory requirements for aPriori applications, there are two primary factors to consider:

  • RAM: Random Access Memory, total hardware memory installed in the host computer
  • Heap: Portion RAM that is reserved exclusively for aPriori.

There are different heap size requirements and different procedures for adjusting heap size for:

  • aP Pro in Creo direct integration mode
  • aP Pro in standalone mode
  • aP Pro bulk costing
  • Enterprise Platform (aP Admin and aP Analytics)

For more information about heap memory requirements and how to adjust heap settings, refer to the following tables and footnotes, and to the aP Pro System Administration Guide.
