Error while opening another instance using the "New Tab" feature in the same IE8 session

Issue while using the NEW TAB in IE8 to open the R12 instance, when another 11i instance is already open in the same browser session.[ID 1322928.1]

Getting the following error:
   Unable to authenticate session.



To implement the solution, perform the following in the second instance:

1. Update SESSION_COOKIE_NAME to a different value than the other instance (it can be set to the same value as the instance name):

update ICX_PARAMETERS
set SESSION_COOKIE_NAME = 'DEV';

commit;

2. Bounce the instance (apps and db).

3. Retest the issue.
