ORA-00845: MEMORY_TARGET not supported on this system (RHEL)

# Solution:
Make sure that /dev/shm is mounted. You can check this by typing df -k at the command prompt. It will look something like this:

Filesystem Size Used Avail Use% Mounted on

shmfs 1G 512M 512M 50% /dev/shm

If you don’t find it then you will have to manually mount it as root user. The size should be more than MEMORY_TARGET or MEMORY_MAX_TARGET.

For example, if the MEMORY_TARGET is less than 2 GB, you should make like that:

#root: mount -t tmpfs shmfs -o size=2048m /dev/shm

I recommend you add an entry in /etc/fstab so that the mount remains persistent even after a reboot.
To make it, add the following entry in /etc/fstab:

shmfs /dev/shm tmpfs size=2048m 0 0
