ethraza Posted August 12, 2005 Report Share Posted August 12, 2005 Hi! Do someone knows how to make hugetlb works under Mandriva LE2005 Download Edition? I'm asking it, becouse I belive that it is the answer for how to get large SGA (>1.7G) w/ Oracle under Mandriva Linux. Am I right? I don't want to be forced to use Fedora, SUSE, or White Box. I like Mandriva. So please ... Thanx 4 n F1! Quote Link to comment Share on other sites More sharing options...
scarecrow Posted August 12, 2005 Report Share Posted August 12, 2005 (edited) AFAIK support for it is already included in the -mm tree of the Linux kernel. Can't be sure if it's disabled by default on Mandriva for some reason (there seem to be some issues with it and memory management), but enabling it and rebuilding the kernel should be fairly simple.

ethraza Posted August 17, 2005 Author Report Share Posted August 17, 2005 Thanks 4 the reply. :D The HugeTLB is in all Mandriva kernels but is disabled by default. If anyone wants to active this... As root do a make menuconfig in /usr/src/linux and go in File systems ---> |- Pseudo filesystems ---> [*] HugeTLB file system support <- Mark that option with * (spacebar), exit and save .config So as root: make make install make modules_install And boot with your new custom kernel. Now Oracle (9i with latest patches or 10g) can create a SGA with more than 1.7GB. Course that you need at least 2.5GB of RAM to create a SGA with more than 1.7GB And with libaio, the Oracle flyes high. (search Mandrivausers.org for my Async IO post.)
