Steven Chan's "Identity Crisis: Are Patches to EBS 11.5.9 Equivalent to 11.5.10?"

I was going through Steven Chan's "Identity Crisis: Are Patches to EBS 11.5.9 Equivalent to 11.5.10? - very well explained from Oracle and Support perspective for Apps customers, gave me a food for thought and hence this post of mine.

From Apps DBA perspective, the way to resolve this confusion is to follow the simple checks.

#1. Check the release name/Applications version using the sql .

select release_name from fnd_product_groups.

#2. The patch readme is the ultimate source of truth to know if the patch can be applied for 11.5.9 instance. Lets take up an example of applying ATG Rup 4.

Pre-requisite section of Read me for 11i.ATG_PF.H.RUP4 (4676589) points out this very clearly.

==End clip==

So, for Apps DBAs source of truth should be patch readme and I guess there is no Identity crisis out there.

Enjoy !!
