I need to upgrade database from 126.96.36.199.0 to 188.8.131.52.0 . But 184.108.40.206.0 database is not available for download in oracle downloads. How do i download 220.127.116.11.0 and bring the links for upgrading process
18.104.22.168 is a patch on top of 22.214.171.124 - it is available in My Oracle Support (https://support.oracle.com), access to which requires a paid support contract. You will need to install 126.96.36.199, then apply the 188.8.131.52 patch.
Is there a reason you cannot upgrade to the latest 184.108.40.206 version ?
