E-Business Suite 12.2 Integrated SOA Gateway, Patch Application Post Installation issues

After the latest Integrated SOA Gateway patch upgrade, the iRepository (iRep) page hangs or the performance is slow.

In the applications users may report a 'Failure of Weblogic Server Bridge' error while waiting for IREP page to load:

"No backend server available for connection. timed out after 10 seconds or idempotent set to OFF or method not idempotent."

In oacore logs the following errors will appear:
