Unable To Authenticate Session in Oracle APPS

 

ERROR

When accessing various Oracle E-Business Suite Release 12.1.x instances through Microsoft Internet Explorer versions 8 to 11, users encounter a specific problem. After successfully logging out from one instance and attempting to log in to a second or third instance, often a cloned version, an error message appears stating

‘Unable to authenticate session.’

Interestingly, this issue does not occur in all instances; login works as expected in some cases, but in others, particularly with cloned instances, this error consistently arises.

SOLUTION

To overcome this and maintain independent sessions, the following methods can be used:

• Open a new explorer window using its own session cookie by selecting File -> New Session from the Menu Bar in an existing browser window.
• Run from the command line adding the -noframemerging parameter

          e.g. Start -> Run -> iexplore -noframemerging

• Start -> Program Files
• Right click on the Internet Explorer icon and select Properties
• Add -noframemerging to the end of the link in the Target field

         e.g.“C:Program FilesInternet Exploreriexplore.exe” -noframemerging

• Click the OK button to close the window
• This icon may then be copied to the desktop if desired
