Oracle decided to integrate PeopleSoft patching into their main database for patch fix, and in the process the commonly used Update ID, has been change to be associated with what I call the Bug Incident, but they are referring to as the Patchset in ARU.
The ARU is Oracle’s Automated Release Update system and has gone by various other names. Since I maintain a few patch lists I have some serious updating to do, but at least they made some nice documents to show the old and new numbers. The new system appears to be clunky and difficult to to use like all new patch systems in the past. Hopefully it will get easier to use and understand with some more use. Good luck!
