Editing patch driver files
Oracle Support provided us with a large EBS 12.1.3 patch to fix a small problem. We cannot justify the test resource for this, and Oracle Support confirmed that only 2 of the objects in the patch are needed (the large patch provides the same code-base that they used for testing but there are no dependencies). They were not willing to provide any further assistance (e.g. helping with an on-site fix, providing a targeted patch).
Has anyone ever used adpatch to load customization into EBS? E.g. creating your own patch driver with patch numbers in an unused range (e.g. 100012345678)? Or has anyone ever edited the uXXXXX.drv file of a patch to remove (comment-out) all objects other than a small number of objects that are required, and amended the patch number (as described here)?
