Connecting Cognos 10.1.1 to Oracle 12.1.0.2 C

[afzaki7]

Hi,
I have a problem starting Cognos when I link it with a content store schema on Oracle 12 C
I think it may be a compatibility issue but I wonder if there is any work around to handle it

I got this errors
09:01:18, CM-CFG-5063 A Content Manager configuration error was detected while connecting to the content store.  CM-CFG-5027 Unable to upgrade the content store to the version 6.0022 that is compatible with this version of Content Manager. The current version of the content store is 7.0027.
