You’ve likely heard that EBS 12.2 now gives users the ability to apply patches while the system is online. But you may not have heard that there’s a catch: certain functionality is disabled while online patching is in progress.
When the adop prepare phase is run, an “Online Patching In Progress” (ADZDPATCH) concurrent request is submitted and stays running until cutover is performed. This prevents certain predefined concurrent programs from being started, requiring them to already be active while a patching cycle is in progress (that is, while a database patch edition exists). The flow of control is as follows:
-If the concurrent managers are all down, the prepare phase continues, with ADZDPATCH entering a status of pending (with the highest priority) until the managers are started.
-If the concurrent managers are partially up, but there is no manager defined that can run ADZDPATCH, then the prepare phase will exit with an error.
-If the concurrent managers are up, and there is one defined that can run ADZDPATCH, processing will loop until ADZDPATCH changes status from pending to running (as long as no incompatible programs are running). The prepare phase then continues.
Note: ADZDPATCH is cancelled when the cutover phase is complete.
If you don’t want a custom program to run while online patching is in progress, you’ll have to make that program incompatible with ADZDPATCH.
To see a list of all the programs that are incompatible with ADZDPATCH, run the concurrent request Concurrent Program Details Report.
Sample output from our 12.2.4 instance is shown below. “XML Publisher Template Re-Generator” is the only program that will not run when online patching is in progress.

During an online patching cycle, the following product functions will be restricted. Before you commence patching, you should therefore ensure there will be no requirement for any these actions or features until the cycle is complete.
