      • 15. Re: SHMALL Sizing with Oracle Automatic Memory Management (AMM)

        I'm not trying to accomplish anything specific other than to provide a good answer. You will have to ask the previous poster and the original poster about their doubts or questions.


        The assertion was made that an ASM instance and and a database using ASM storage have to use the same memory management, which is incorrect. Under Linux, every database instance using more than 4 GB of RAM should definitely use kernel hugepages for memory efficiency and performance. ASM runs best under Posix shared memory and AMM.
