Try to Clear Cache:
=============

In 11i use the apache start and stop commands and bounce the JVM running on JSERV and clear caches as follows:

To clear the jsp & modplsql caches run this command:

1)shutdown apache
2) verify ps xuc | rep http -- should not return any process
3)rm -Rf $OA_HTML/_pages/*
rm -Rf $COMMON_TOP/_pages/*
rm -Rf $IAS_ORACLE_HOME/Apache/modplsql/cache/*
4). start apache

From user point of view user needs to clear the brower cache

goto IE--> tools--> delete cookes
--> delete files

---> clear History

Once the above workaround is done, it should have resolve the issue. try login and verify the result.


Hope it should fix the issue.
