While configuring a sandbox environment, I got CLSRSC-184: Configuration of ASM failed error. This can have various causes but examining the log revealed the phrase “ORA-00845: MEMORY_TARGET ORA-00845: MEMORY_TARGET not supported on this system during root.sh”
SOLUTION: check the size of /dev/shm
mount -t tmpfs shmfs -o size=2G /dev/shm
