EBS R12.1 Login Page is not coming up
EBS r12.1 login page is not coming up. I have tried many steps to troubleshoot this issue but unable to resolve this error. After a clean shutdown/start of the db tier and apps tier, the login page is coming up for few minutes. Then suddenly it is going into to a white/blank page. Kindly provide me with some leads.
Any help is appreciated.
