Last updated on FEBRUARY 23, 2023

Applies to:

Oracle Applications Framework - Version to [Release 11.5.10]
Information in this document applies to any platform.
Oracle Self-Service Web Applications - Version: 11.5.2 to 11.5.10
Information in this document applies to any platform.



This note is designed to help you investigate problems with logging into the Home Page with your Applications 11i system. (11.5.2 – 11.5.10+)

The fact you are unable to login to Oracle Applications 11i can be a symptom of a completely different underlying problem. So it is important you determine the root cause of the login failure.
The troubleshooting steps provided are intended to help reach that root cause. Login issues can be divided into 2 broad categories. The first category is where login page does not render at all. In other words the main page is completely inaccessible or unuseable. The second category of problem is issues encountered after entering a username & password combination. In this category are things like: errors received because the system is unable to process the login request, or after login the homepage is not rendered.

This note does NOT address issues that occur after a successful login; such as forms not launching or javascript errors when selecting a responsibility or missing responsibilities.

This note does NOT cover SSO or 10gAS login issues. (For SSO/Portal issues see Note:146469.1 , Note:233436.1, Note:186981.1)

Throughout the history of 11i the login process has undergone several changes. In order to provide the most comprehensive troubleshooting guide possible we will include all things that need to be checked. Some of these may not be applicable for your version of Oracle Apps.

Where the check requires a specific version this will be indicated…. If you are unsure of your version, do the check and report the results.

Some of the recent changes in the login process include:
As of FND.G / 11.5.9 maintenance pack, there is a new URL to launch Applications, namely:
http://<host name>.<domain name>:<HTTP port>/oa_servlets/AppsLogin
See Note:226825.1 - Release 11i, Oracle Application Object Library Mini-pack FND.G

As of 11.5.10.CU2 the ICXINDEX.htm page has been modified to re-direct you to oa_servlets/AppsLogin

Approach to Troubleshooting

Error messages will not necessarily indicate the root cause of the problem so it is important to collate information on the scope and nature of the problem.

• Was it working previously? If so, what has changed, are all the Server processes running?
• Are all users affected? If not, what is common link to users with problem?
• If this is a single user issue, does it only affect the one PC or user id? What are the user level profile options for this particular user?
• Is the problem confined to one network segment or one PC?
• Do you get different behaviour in Internet Explorer to Netscape browser?
• What is your instance architecture? Are you using load balancing, RAC, SSO, etc.?

 The troubleshooting tips below have been split into the quick checks that can be done easily on the fly, and detailed checks that may involve bouncing servers and may require editing files/packages so will need to ensure they can be restored if required.
