Oracle Apps R12 – Fix for "Cannot Complete Your Request"

When working with Oracle E-Business Suite (R12), you may sometimes face the error "Cannot complete your request" while accessing certain pages or forms. This usually happens due to an incorrect guest user password configuration in the context file.

error:

“Cannot complete applications logon.
You may have entered an invalid applications password,
or there may have been a database connect error.”

The problem usually occurs when the GUEST user password in the context file doesn't match the actual database setup. This leads to authentication failures in Apache, JServ, and other components.

It was clear that GUEST password was out of sync. Since we could not pinpoint where the issue was we followed this strategy to solve this issue:

1. Change the s_guest_passwd to GUEST/GUEST in context file and run autoconfig.
2. Checked everything was working fine, including Apache, Jserv, Forms
3. Changed back s_guest_passwd to GUEST/ORACLE in context file and run autoconfig.
