Where did you change this value?
Your capitals would seem to indicate that you hacked on the kernel,
but the new place to tune such parameters is /proc/sys/kernel/shmmax.
It would seem to default to 32Mb, which isn't nearly enough for a
big Oracle setup.
# echo `expr 1024 \* 1024 \* 1024` > /proc/sys/kernel/shmmax
should allow you 1Gb of shared memory.
Matthew.
