it would be my pleasure to assist you on this issue
unfortunatley shared hostings doesn't allow you to install anything on your account, you are bound to whatever the hosting company installs on the server.
In case you need to install special software you should look for a dedicated hosting account.
If you are interested, i can send you recommendations. alternatively you can look for shared hosting plans that support the oracle version that you intend to use.
let me know the version so i can research a hosting plan for you.
