Below is the error message I received while I was trying to install Oracle Database 19c on Oracle Linux 7.
PRVF-7573 : Sufficient swap size is not available on node
As per my error on the installer screen I needed 16GB of SWAP space where as my system has just 4GB. So I need to add a swap file for the installation to continue.
Below steps will outline the steps for the same.
dd if=/dev/sdb of=/tmp/swap01 bs=1K count=16M
chmod 600 /tmp/swap01
mkswap /tmp/swap01
swapon /tmp/swap01
Make sure the bs (*) count is equal to your required SWAP space. Also, the /dev/sdb has enough storage as needed
