Advisory mode

In advisory mode it is possible for an application to have some of its heap segments backed by large pages and some of them backed by 4 KB pages. The 4 KB pages back the data or heap segments when there are not enough large pages available to back the segment.

In advisory mode, the application uses large pages if possible, depending on the following conditions:

• The userid is authorized to use large pages.
• The system hardware has the large page architectural feature.
• You defined a large page memory pool.
• There are enough pages in the large page memory pool to back the entire segment with large pages.

If any of the above conditions are not met, the application's data and heap segments are backed with 4 KB pages.

Executable files that are marked to use large pages run in advisory mode.
