I need to upgrade database from 220.127.116.11.0 to 18.104.22.168.0 . But 22.214.171.124.0 database is not available for download in oracle downloads. How do i download 126.96.36.199.0 and bring the links for upgrading process
188.8.131.52 is a patch on top of 184.108.40.206 - it is available in My Oracle Support (https://support.oracle.com), access to which requires a paid support contract. You will need to install 220.127.116.11, then apply the 18.104.22.168 patch.
Is there a reason you cannot upgrade to the latest 22.214.171.124 version ?
