memory_target needs larger /dev/shm

Starting ORACLE instance (normal)
WARNING: You are trying to use the MEMORY_TARGET feature. This feature requires the /dev/shm file system to be mounted for at least 1258291200 bytes. /dev/shm is either not mounted or is mounted with available space less than this size. Please fix this so that MEMORY_TARGET can work as expected. Current available is 973942784 and used is 1173540864 bytes. Ensure that the mount point is /dev/shm for this directory.
