GBLPAGES

   GBLPAGES sets the number of global page table entries allocated
   at bootstrap time. Each global section requires 1 global page
   table entry per section page, plus 2 entries, with the total
   rounded up to an even number.

   Users with CMKRNL privilege can change this parameter on a
   running system. Increasing the value of this parameter allows
   the global page table to expand, on demand, up to the maximum
   size.

   The default value is sufficient for the images normally installed
   as shared in the system startup command procedures. Once the
   system is running and all global sections are created, you can
   examine the actual requirements with the /GLOBAL qualifier of
   the Install utility (INSTALL) and reduce the value of GBLPAGES
   accordingly. However, do not set the value of this parameter
   too low, because the page table entries use little permanently
   resident memory. If you plan to install many user images as
   shared, or if user programs are likely to create many global
   sections, you must increase the value of this parameter.

   GBLPAGES has the AUTOGEN, DYNAMIC, FEEDBACK, GEN, and MAJOR
   attributes.
