Because yesterday Oracle launched a Patch Critical Oracle Java SE October 2011, I realized that my server has:
O/S: Red Hat 5 Enterprise Edition
java version "1.6.0_06"
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) Client VM (build 10.0-b22, mixed mode, sharing)
According to this page: https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&id=1361232.1
I have to upgrade my JRE version using patch for Linux: jre-6u27-linux-i586.bin

How do I upgrade JRE?
a.- Should I first uninstall JRE version 1.6.0_06 and then install a fresh jre-6u27-linux-i586.bin? Won't it affect anything at my web server?
b.- Should I just install jre-6u27-linux-i586.bin no matter what?
c.- Should I follow some procedure to upgrade my JRE version?
