Oracle 11gR2 Performance Tuning for RHEL 6.6

Can someone please confirm that the document titled "Deploying Oracle Database 11g R2 on Red Hat Enterprise Linux 6 - Best Practices" has not been updated since Ver 1.4, dated December 2013?

I'm getting lots of questions on the Red Hat recommended tuning parameter settings for Oracle 11g R2 and this seems to be a good source of information. I just want to be sure I have the latest revision.

Can someone please confirm this?

Thanks.

Shaun.
