What is the difference between CPU, PSU, PSE, and MLR? I see all of these terms in the MOS (My Oracle Support) patching recommendations but no explanations.

What is the difference between CPU, PSU, PSE, and MLR? I see all of these terms in the MOS (My Oracle Support) patching recommendations but no explanations.
I know what a PSU and CPU are. CPU="Critical Patch Update" and it includes only security related patches. PSU="Patch Set Update" and it includes the most recent CPU plus additional non-security bug fixes.
What are PSE's and MLR's though and how do I know if I really need them?
Also I thought Oracle said once you start applying PSU's to an oracle home you should not revert back to CPU's, however in my OMS home I've applied PSU's, yet the patch recommendations both in Grid Control and MOS are recommending the latest CPU. Do I have it backwards? Is it ok to go from PSU to CPU but not CPU to PSU? Received on Wed Apr 28 2010 - 09:52:23 CDT
