Why it will not be helpful here?Because we cloned from SSO instance to SSO instance?Kindly let me know.
Well, I assumed this was already done as part of the clone (see doc referenced below) since keeping references in a cloned instance would cause issues (like (Doc ID 730982.1)).
You may give it a try if you want since this is a test instance and see if it helps.
Registering Oracle E-Business Suite Release 11i with Oracle Internet Directory 11gR1 and Single Sign-On (Doc ID 1536984.1) -- Section 5: Remove References
Sure i wll go through the docs and check them and will let u know once done.
