E-Business Suite 12.2's Online Patching feature allows you to apply patches to your environment while it is still running. For example, you can apply patches to Financials while your end-users are entering bills in Accounts Receivable. These patches are applied using our Applications DBA (AD) and EBS Technology Stack (TXK) tools.
A reader recently asked whether it's advisable to apply our latest EBS 12.2.7 update at the same time as our AD-TXK Delta 10 updates. This is a great question, since it touches on both our goals for our AD and TXK tools as well as our internal testing practices for new updates and patches.
The short answer: You should apply the latest AD and TXK infrastructure tools in an initial patching cycle, and then apply EBS updates and patches (e.g. EBS 12.2.7) in a later patching cycle.
There are two reasons:
Do new AD and TXK patches trigger functional re-testing?
New AD and TXK patches do not change any aspects of how EBS functional products work. These infrastructure tools affect how patches are applied, not how patches work.
In other words, having the latest AD/TXK updates may reduce the risk of applying, say, a new HRMS patch, but it will not affect any Human Resources-related functionality at all.
Likewise, applying the latest AD/TXK update does not affect the functionality of any existing EBS products. Infrastructure tools only affect the patching process, not how installed EBS products work.
How do I find the latest AD and TXK tools?
