Understanding the Oracle E-Business Suite (EBS) R12.2 Login Flow

By -

EBS applicatations User access the Oracle Application login page from the below URL

http://<URL_HOSTNAME>:<PORT>

Ex:-

http://vtebs.oracle.com:8000/OA_HTML_AppsLoginin

From this URL will be redirected to the central login page,

In the http.conf file, locate DocumentRoot. The DocumentRoot is the base location for where the first access the apache file is stored.

Locatation:  $FMW_HOME/webtier/instances/EBS_WEB_OHS/config/OHS/EBS_web/httpd.conf

Ex:- DocumentRoot: "/u01/applmgr/DEV/fs1/inst/apps/dev_ebsvis/portal"

Under this DocumentRoot folder, index.html will redirect to the application login page.

http://<URL_HOSTNAME>:<PORT>/OA_HTML/AppsLogin

The application identified the context in OA_HTML and redirected the connection to the OACORE server.

The application connects to the database using the APPLSYSPUB user and displays the login page. The password was obtained from the DBC file.

The password for APPLSYSPUB is available in two locations: $FND_SECURE and CONTEXTFILE.

The user enters their username and password and then clicks the login page.

The application user credentials are validated using the FND_USER database.

The user now sees the login page.

Users click on Responsibility after logging in, and the application connects to the APPLSYS user and validate the user permission to the responsibility.

If user validation is successful, the user connection is established as an APPS user, and the user can use the responsiblity.
