How to apply July 2011CPU
we have a Oracle database (11.2.0.1.0) hosted on a CentOS 7 server, found multiple vulnerabilities by scanner, I download the CPU (p12419278_112010_LInux-x86-64.zip) from MOS, but there are many sub-folders inside this zip file, which one should I apply or should I apply them all? and what are these numbers mean?
