ADOP intelligent warnings, the ever-fluid recommended tech patches, and multiple versions of the truth

Filed under: R12.2 — kkempf @ 1:34 pm

So there I was..

Running adop phase=prepare in my production R12.2 environment, and I notice a warning on the screen and in the logs:

[WARNING]   The following required database bug fixes <19393542> are missing from this node, <database hostname>. Refer to My Oracle Support Knowledge Document 1594274.1 to identify the patch that delivers this bug fix.

This raises some questions:  How did adop know I needed a patch?  How serious is this?

Consolidated ≠ Updated

I went and pulled Consolidated List of Patches and Technology Bug Fixes (aka Doc ID 1594274.1) and it’s changed a bit since we went live.  Mind you, I expected to find patches in there we hadn’t applied as part of our go live; we locked our code last October before the upgrade.  What I didn’t expect was to find 14 patches on the database alone.  After some tedious cross checking of my inventory versus the document, I remembered (patch 17537119).

Patch 17537119 is really cool. This little gem compares an .xml file in the patch with your inventory, and tells you what you’re missing.  Sweet!

One lies, one tells the truth

I realized that the output of did not agree with 1594274.1.  In fact, it contained more patches than 1594274.1.  I would have assumed they were aligned, and this is really confusing as a customer: Which one is the definitive source?

In the end, I went with the, since it was a superset of the information contained in the Consolidated List of Patches and Technology Bug Fixes.  Perhaps a name change is in order?
