How can I create a SHA2 certificate using Oracle Wallet if I have only Oracle 11.1 database?
I already tried and read a lot about SHA-2 under Oracle 11.1 db version but it´s not possible according to Oracle documentation.

You can't. You have two options:
Upgrade Oracle to at least version 12.1, or
Use a public domain version of SHA256 (which is SHA2). See SHA1, SHA256, SHA512 in Oracle for free without using DBMS_CRYPTO – Jakub Wartak's blog
