To revert it back to storage just run following command and REBOOT machine to be effective.
systemctl mask tmp.mount

--run installation from "database" directory
./runInstall1. Uncheck checkbox “I wish to receive security updates via My Oracle Support” and then click “Next” button.

9. Summary screen just before installation. It’s the last moment to make changes in previous steps. If you are ready click “Install” button.
10. Installation begins …
11. Unfortunately I received error during binaries linking
in log you should see
/usr/bin/ld: note: '__tls_get_addr@@GLIBC_2.3' is defined in
DSO /lib64/ld-linux-x86-64.so.2 so try adding it to the linker
command line /lib64/ld-linux-x86-64.so.2: could not read symbols:
Invalid operation

19. You should see summary screen for your database. You can click “Password Management” to unlock and change passwords for default account. Click “OK” button.
20. Installation is finished. Click “Close” button.
21. Post installation steps
