Program memory (Program Execution Area) for managing the fixed data of an ABAP program while it is being executed. The PXA notably contains the byte codes of all programs running concurrently at a specific time on an application server. This memory is shared by all internal sessions of the application server 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 the data being reloaded from the database if the program is executed again. As well as byte codes, the PXA also buffers shared resources like the values of constants and facilitates the initial value sharing of boxed components.
