I'd have to defer to other experts on whether it makes much difference to have ASM in hugepages. From what I've read, there's really not much reason to have asm using any hugepages. Chris

Taylor,
ASM uses memory anyway so why not give hugepages to it ? I see at least one benefit - if there will be paging on the system your ASM's SGA will not be paged out.

The reason for this question was nitpicky - ASM is using about 14 hugepages when it starts up which isn't much. Just kind of annoyed me - probably due to lack of sleep lol

Guys/Gals,
I'm in the process of configuring hugepages in 10.2.0.4 RAC.
Since ASM starts up first, how I do prevent it from using any of the hugepages?
Regards!
