we are using the Microsoft Internet Explorer 8 (IE 8) to access your Release 12.1.x E-Business-Suite Instances, for example PROD, TEST and DEV.
When we logout from DEV Instance and want to login to the TEST- or PROD-Instance it happens, that we see following error :
Unable to authenticate session
we need to start the Internet Explorer with the option '-noframemerging', as described in Note 389422.1 - 'Recommended Browsers for Oracle E-Business Suite Release 12' under the Known issues.
Previous releases of Internet Explorer have allowed users to logon to the same Oracle E-Business Suite environment concurrently from the same desktop by launching each application session through a new browser session. By default the ‘Session Merging’ feature within IE8 and IE9 prevents this functionality from working by default. This is because the same session id is used when accessing the same Oracle E-Business Suite environment despite opening a new browser window to launch the second session. This can result in unusual behavior with invalid sessions causing errors such as “Your login session has become invalid" and failures to launch forms causing errors such as “FRM-92050: Failed to connect to the server: /forms/formservlet: -1"
To retain the use of multiple sessions to the same Oracle E-Business Suite environment with IE8 and higher please use one of the workarounds below to ensure each browser session remains independent;
Run from the command line adding the -noframemerging parameter e.g. Start -> Run -> iexplore -noframemerging
Create a new IE8 icon adding the -noframemerging parameter e.g.
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 Files\Internet Explorer\iexplore.exe" -noframemerging
Click the OK button to close the window
This icon may then be copied to the desktop if desired
