/PAGE_TABLES (default)
       /NOPAGE_TABLES

    Reserves additional memory for shared page tables. 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 only 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.
