We are installing OEM13C in REDHAT 6.8 and pre-requisites are getting failed due to the non-certified version.

However the EM 13.1 installation process doesn't recognize 6.8 as a certified version of RHEL 6. The error from the installer is shown below. The installer will not allow this to be skipped so the install can continue.   13.1 EM install does not support on RHEL6.8. This is taken care in next release of 13c OEM.

We must use DBMS_RCVMAN.SetDatabase to select a database from the recovery catalog schema before you can use this view.
