When shmmax is set to 8589934592 (which is half the size of RAM ), Database startup fails with error ORA-27102. This is no matter what the init.ora settings are (whether sga_max_size, sga_target etc.. are set or not)
If shmmax is set to any other value (even 8000000000, or 4294967295, or 12000000000, or
16000000000, ...) the database starts OK.
ORA-27102: out of memory
