That seems to only apply to Windows, and I am trying for my database instance, not ASM instance. The MOL suggested the same thing but I do not think it applies here.

I have been trying to get hugepages working on 11gR1 without success. Has anybody been able to get this to work properly? In order to use hugepages, you have to turn off 11g ASMM which uses the /dev/shm memory mapping.

Hugepages are configured properly in OS, /etc/security/limits.conf updated for hugepages. If I attempt to set memory_target and memory_max_target to zero (or reset them) then I get ORA-00849 SGA_TARGET ### cannot be set to more than MEMORY_MAX_TARGET. I am following technote 749851.1, and even opened a support case with Oracle, and I am not getting anywhere.

Any clues as to what I am missing? Thanks- Jon
