Fails in what sense? If you set USE_ISM = TRUE on a system that doesn't support ISM (e.g., any Ultra system), Oracle simply won't use ISM; it should still start and run fine. (Not that I've tried it under Solaris 2.6.)

ISM (intimate shared memory) is a type of shared memory that stays resident in RAM at all times. As such, it's a Good Thing in many cases, because your SGA won't get swapped out. However, it effectively reduces the amount of RAM available to non-RDBMS processes, so if you run a lot of other processes on your system, they may perform poorly with this parameter set.
