At least with hugetlbfs we can chmod the filesystem to be owned by the oracle user. -ben On Thu, Nov 14, 2002 at 01:02:20PM -0800, William Lee Irwin III wrote: > On Thu, Nov 14, 2002 at 12:30:35PM -0800, William Lee Irwin III wrote: > >> The main reason I haven't considered doing this is because they already > >> got in and there appears to be a user (Oracle/IA64). > > On Thu, Nov 14, 2002 at 03:48:09PM -0500, Benjamin LaHaise wrote: > > Not in shipping code.
