I am trying to upgrade my Jdeveloper from 220.127.116.11 to 18.104.22.168.0. The installation fails with the message: "The product maintenance level of the current installer (Jdeveloper and ADF:22.214.171.124.0) is not compatible with the maintenance level of the product installed on your system (Jdeveloper and ADF:126.96.36.199). Please obtain a compatible installer or perform maintenance on your current system to achieve the desired level".
So i wonder:
-what is maintenance level?
-is there a compatible installer? If yes,where?
-how do i perform maintenance on my current system to achieve the desired level?
Please, i need some help to fix this. I am trying to convince my customer that Jdeveloper is the right tool and i get stuck on what i thought was a simple upgrade.
Well that's useful information, but i haven't even come to the point where i choose where to install Jdeveloper yet. The very first page asks me to choose middleware home directory. It's right after that that i get this message. Do i have to create a new middleware home? will there be a migration of what i've created in my old one (data sources for instance)?
When you first run the new install of JDeveloper, it will ask you if you want to migrate settings from an earlier release; you should answer "yes" to get all of the configuration (including IDE data sources) migrated.
what were you doing wrong? Can you please tell? I am facing a same situation. I have installed weblogic generic installer and now when i try to install ADF libraries using the jdev generic file i get this error
