/PAGE_TABLES (default)
       /NOPAGE_TABLES

    Reserves additional memory for shared page tables system as
    specified on the command line. (The default is taken from the
    existing Memory Registry.)

    When the memory-resident global section is created, shared
    page tables are created for the global section. If you do not
    specify /ALLOCATE, or if you specify /NOALLOCATE, the additional
    reserved memory is deducted from the system's fluid page count.
    If you specify /ALLOCATE, additional pages are allocated for the
    shared page table during the next reboot of the system, and the
    additional reserved memory is deducted from the system's fluid
    page count.

    If you do not specify /PAGE_TABLES, or if you specify /NOPAGE_
    TABLES, additional memory is not reserved for shared page tables.
    When the memory-resident global section is created, shared page
    tables are not created for the global section.

    You cannot specify /PAGE_TABLES if the reservation has the
    attribute /NOGLOBAL_SECTION.
