Re: Oracle Patches - PSUs/CPUs/Caveats question/confusion

I can provide a little information, but I don't do windows ...
- 8708078 appears to be a "Patch Bundle". Patch bundles were/are a convenience for applying lots of (recommended) fixes. Though it resembles a CPU/PSU, it appears to be different (to me). A big difference for me is that it isn't necessarily a security-related set of patches and it doesn't have the CheckPreReq that I love about PSUs.
- *Patch Sets are not patch set updates.*
- Patch Sets are applied to a base release and may be applied over a
previous Patch Set. The installation tool is OUI. For example,
a base release. Applying Patch Set 1 gets you to 10.2.0.2.
Set 3 gets you to 10.2.0.4. (For version 22.214.171.124 and beyond,
Patch Sets do
not require a base release install and basically may be thought
of as being
installed into a new home).
- CPUs are bundles of security fixes that are applied on top of a base release/patch set. The installation tool is opatch. As I prefer PSUs, I'll not say more about CPUs.
- PSUs are produced on the same schedule as CPUs and are bundles that include CPU patches plus other selected fixes. If you choose to use PSUs, you don't, and may not, use CPUs. I love PSUs. With the prerequisite checker, I know before I shutdown the home whether the PSU will apply. Wonderful! On at least one platform, CPUs are no longer available. If you apply PSU#1 to 126.96.36.199.0, your database will be at level 188.8.131.52.1 (though 10.2 and 11.1 do not update the final digit on most references, leaving it at 184.108.40.206.0, for example. "opatch lsinventory" will display the entire 220.127.116.11.1).
Hope this helps!
