I have multiple 10rR2 installs (customer requirements). Each install is identical in its patching and all have been patched through August 2013. I started using the PSU method of patching in Oct 2010.
Recently a security scan via Nessus showed that CPUs from 2006 have not been installed. My OPatch history shows that I installed every quarterly security patch since the 10g install in Oct 2009. Since the CPUs and PSUs are cumulative, shouldn't all the 2006 patches already be installed? And what means would I use to verify other than my OPatch history? Thanks in advance.
