HP-UX 11i September 2001 Release Notes

Process, Threads, Memory, and Kernel Parameters
Memory Windows
Chapter 8
134
• Setting max_mem_window to one creates a single memory window to accompany the
existing global memory window, or a total of two memory windows one default and
one user-defined.
• Setting max_mem_window to two produces a total of three memory windows the
default and two user-defined.
• Setting max_mem_window to 0 leaves only one memory window, the default or global
memory window.
What should the value be? That depends on the application requirements and the
applications installed on the system. HP recommends that each ISV/application should
document how many windows it intends to use.
Use of memory windows does not affect the performance of processes. There is no size
requirement associated with memory windows. Any machine running HP-UX (32-bit or
64-bit) and any hardware supporting HP-UX release 11i can use memory windows.
