You are correct! The ora_dism process must run as root in order to be able to dynamically allocate/deallocate ISM segments. If it is not present, DISM will work but performance will stink since each access to memory will have to go through a mutex...yuck. So make sure it is there and has SUID root permissions.
Anyway, since the ora_mman process monitors memory and decides on allocation, it does work with the ora_dism process in-order to actually do the memory adjustments. Think of ora_mman as the brains and the ora_dism as the brawn. hope this helps, Glenn This message posted from opensolaris.org _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
