R12 - Logon is not working, no error message is shown

After the clone of an E-Business Suite Instance Release 12, the logon was not working as expected on the target Instance.

Launching the logon URL
http://.:

is redirected to
http://host.domain:port/OA_HTML/AppsLocalLogin.jsp

Result :

Nothing happens - no Homepage screen is presented, neither an error message is brought up.

Cause:
The cause has been identified as JSP- or Class-File corruption under the $COMMON_TOP/_pages.

The corruption could be a result of a wrong CLASSPATH Setting in the Environment, as the System itself was not able to access the Classes.

Solution:
Please execute the following steps :

1. Open a new Shell and source the APPS User Environment

2. Change into the $FND_TOP Patch directory

cd $FND_TOP/patch/115/bin

3. Compile the JSP files using following command :

perl ojspCompile.pl --compile --flush -p 2

4. Initiate the execution of Autoconfig on the DB- and the APPS_Tier(s)

5. Start the APPS-Tier(s) Services again and re-test the logon
