What is PXA in SAP (BC-ABA - ABAP Runtime Environment)?

SAP Term: PXA

• Component: BC-ABA

• Component Name: ABAP Runtime Environment

• Description: Memory for managing the fixed data of an ABAP program while it is being executed. PXA stands for Program Execution Area. The PXA primarily contains the byte codes of all programs running simultaneously at a point in time on an application server. This memory is shared by all internal sessions of the application server and there is only one on each server. The byte code of a program that is executed once remains buffered in the PXA for as long as possible, as a program load, to prevent it being reloaded from the database when the program is executed again. Furthermore, the PXA buffers shared resources, such as values of constants, and enables initial value sharing in boxed components.
