I thought that was AIX (others?) specific but that's a good question. Seems like I read that AIX does that but not positive.
Actually, I know for sure that it doesn't on Linux because it RESERVES hugepages but doesn't use them - you can watch the free hugepages count go down as Oracle claims memory I believe. I'll try to verify on my end however.

When you have enabled huge pages, and verified that your SGA is going into the huge pages pool, Doesn't the SGA get pre-paged regardless of this particular parameter (pre_page_sga)?
The way I understand it, with huge pages enabled, the SGA is loaded(paged-in) completely on instance startup. Do I have a misunderstanding?
