Hi Support, My production instance is running with database 11.2.0.3. I suppose to upgrade the current database to 12.1.0.2 version. As advised in this SR , i was instructed to follow below Doc ID's to upgrade my database (11.2.0.3) to 12.1.0.2 . Note 1503653.1 Complete Checklist for Manual Upgrades to Oracle Database 12c Release 1 (12.1) I followed this note (1503653.1) and performed each tasks on db and apps nodes and finally the database upgrade was done, Upon the database upgrade completion, I am trying to access the application. I am unable to connect to the application and it redirects to blank login page. The login page doesnt open after the database upgrade. When accessing the login url in IE and edge browsers, login url redirection happens on the browser and immediately blank page displays on browser Please advise me for fixing this issue Thanks , Karthik
