Just to make you aware of the upcoming end of the grace period, we blog about this again:
The 
Oracle Lifetime Support Policy states that once a new version is released, older versions of a product get a grace period in which they still receive some maintenance and bug fixing. This grace period is usually one year.
So with the release of 11.1.1.6.0 of OBIEE in March 2012, OBIEE 11.1.1.5.x was put into its grace period.
Now - a year later the OBIEE 11.1.1.5.x grace period will end on March 1st 2013 (also see 
KM Doc 1530991.1 ). This means that there will be no further new fixes, patches, or bug repairs be done to this version.
We therefore recommend to upgrade your system to OBIEE 11.1.1.6.x, by following the steps outlined in the KM Doc: Upgrade Advisor: Oracle Business Intelligence Enterprise Edition (OBIEE) from 11.1.1.5.0 to 11.1.1.6.0 (Doc ID 1434253.1)
