Marking the executable file to request large pages
The XCOFF header in an executable file contains the blpdata flag to indicate that an application wants to use large pages to back the data and heap segments.
To mark an executable file to request large pages,
use the following command:
# ldedit -blpdata <filename>If
you decide to no longer use large pages to back the data and heap segments,
use the following command to clear the large page flag:
# ldedit -bnolpdata <filename>
