Parameter
abap/pxa
Short text
mode of operation of program buffer
Parameter Description
Parameter influences behavior of program buffer It can have following values:
shared
program buffer is used by all work processes; default, cannot be changed
gen_local
ABAP programs are generated in user LUW
gen_local_in_dialog
ABAP programs are generated in dialog processes within the user LUW and in other processes within their own LUW.
gen_remote
where possible, ABAP programs are always generated in their own LUW; default value
protect
program buffer is protected from being overwritten; this addition only has an effect on NT, HP-UNIX und SOLARIS
use_semaphore
semaphores are used to lock the program buffer; default on NT
use_mutex
mutexes are used to lock the program buffers; default on all other platforms
develop
as a rule, a database commit is triggered after an ABAP program is generated. Because this additional database commit influences the behavior of an application, the addition cannot be used in a productive system. In a development system, this additional reduces the likelihood of database deadlocks.
generate
This addition ensures that ABAP programs are, as a rule, generated only before they are used. For diagnostic purposes only.
source
ABAP sources are also loaded into the program buffer.
