Hello Hasan,
I have not been able to login to Oracle EBS R12. It says page not found. When I try to make sure that the Oracle services is running I get a status 4 after I have started the database and the listener. I have attached a screen shot of the log file and here are the last few lines of the main log file.
I cannot copy paste as I already mentioned. However I am just typing it from the text that I see - bottom few lines.
