oracle:system defined limits for shared memery was misconfiguration

Edit /etc/sysctl.conf and ensure the following lines are present:

kernel.shmall = 18350080
kernel.shmmax = 75161927680
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
DBCA Error: ORA-27104: system-defined limits for shared memory was
misconfigured Fix: Increase kernel.shmmax & kernel.shmall based on your Server RAM. Please
refer Oracle Metalink Note [ID 567506.1] – Maximum SHMMAX values for Linux
x86 and x86-64
Example for x86_64 Server with 32GB RAM:
shmmax=34359738368 (=16*1024*1024*1024),
shmall=8388608 (=16*1024*1024*1024 / 4096) – 4096 is page size
