Memory allocation of non-dialog work process in UNIX & Windows

Memory allocation of non-dialog work process in UNIX

In UNIX, if Roll memory gets full Heap memory is occupied and if heap memory gets full extended memory is used.

But
in windows it is different, after roll memory (ztta/roll_first) is
filled the work process uses Extended memory, after extended memory is
fill then remainder of roll memory ( ztta/roll_area - ztta/roll_first)
is used soon..

Unix or Unix like systemsWindows
Roll Memory
up to
 ztta/roll_area
Roll Memory
up to
ztta/roll_first
