Requested URL/OA_HTML/AppsLogin was not found on this server

Applies to:

Oracle Enterprise Linux 5.5

Oracle Application Install - Version: 12.1.1
Database 11gR1

Description:

I recently came across a problem the login page was throwing an error - 404 /OA_HTML/AppsLogin was not found on this server. All services of Database and Listener working fine and get connected. All Application services started successfully without any error/warning on status 0, multiple time restart the services of application and database and also restart the whole machine but still facing the same problem.

Solution:

After some research work I have found the following solution:

The Problem occurs because the wsrp_service.wsdl was owned by root but the services were being started by applmgr.

Ensure that the permission of the file
$ORA_CONFIG_HOME/10.1.3/j2ee/oacore/application-deployments/oacore/html/server-wsdl/wsrp_service.wsdl

Shows that it is owned by root user. Somebody started the services of Apps as root user.
Changed the ownership of the file to Apps Owner.
Restart the service, everything working fine now.

Your comments, especially which will help us improve the functionality, will be greatly appreciated :)
