I have check with Oracle on this and Service Pack 2 is not officially supported, but I would like to see if there is anyone out there running OBIEE 22.214.171.124 with SQL server 2008 R2 Service Pack 2? We are currently running 2008 R2 but without the service pack. Our Oracle team would like upgrade to SP2. If you have run sp2, are you encountering any issues, i.e. performance.
