PXA
Short for Program Execution Area. Memory for managing the fixed data of a running ABAP program.
BEGIN_SECTION VERSION 5 OUT The PXA notably contains the byte codes of all programs running simultaneously on an ABAP_ASINSTANCE . This memory is shared by all ABAP_ISESSNS of the ABAP_ASINSTANCE , and there is only one such memory on each server. The byte code of a program that is executed once remains buffered in the PXA as a program load for as long as possible to prevent reloads from the database if the program is executed again. Furthermore, the PXA buffers shared resources, such as values of constants, and is used for the initial value sharing of boxed components.
