PXA
Program memory ( program execution area ) for managing the fixed
data of an ABAP program found in a n execution. The PXA notably
contains the bytecodes 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 on each server. The
bytecode of a program that is executed once remains buffered in the
PXA for as long as possible as a load
program to prevent reload from the database in the event that the
program is executed again. The PXA also buffers communal
resources like the values of constants and
facilitates the initial value
sharing of boxed component s
