During the post-installation of Oracle Applications Release 12.1.1, you might have an error with the Login page check. The log file would say something similar to:

Login Page

-----------

checking URL = http://localhost.localdomain:8000/OA_HTML/AppsLogin

RW-50016: Error: - {0} was not created:
File = {1}


There could be several reasons this happened.
- Check the permissions on the environment file.
- Check your /etc/hosts entry
- Unlock the apps and applsys accounts on the database
- Run AutoConfig
- Bounce the services

When you bounce the services, make sure they all restart. That means, check the status, stop them and check the status again. Make sure that the OC4J processes have restarted. If you need to, kill the processes on the OS.

[oracle@localhost VIS_localhost]  $ ./adapcctl.sh status

You are running adapcctl.sh version 120.7.12010000.2

Run the status again and make sure all the PID's are different. If not, kill the processes on the OS.
