NOT FOR PRODUCTION! NOT FOR PRODUCTION!! NOT FOR PRODUCTION!!!
So, I can see that WebLogic 12c installation along with forms and reports & configuring for deployment blog posts being accessed quite often. My original posts were referring to WebLogic 12c version 220.127.116.11.0 (or 12.2.1 as documents mention), which is a buggy release from my limited usage. I’ve skipped the next version and was pretty happy with the setup until I came across an oracle blog post about version 18.104.22.168.0
As I had the complete setup fully functional, I decided to upgrade the existing, against going for a fresh installation and configuration (that should have been done!). I just wanted to see how the Oracle software upgrade works in real means…
Today I am going to share my experience of upgrading an existing WebLogic 12c forms & reports environment to the latest release.
So let us have a look at the Oracle products installed on my Windows 10 64Bit Professional edition
- Oracle developer suite 6i (for supporting legacy application that is 20 years old)
- Oracle developer 10g (to support our EBS R12 Business application)
- Oracle database 11gR2
- Oracle database 12c (for weblogic repo)
- WebLogic 12c 22.214.171.124.0
- Forms and reports 12c 126.96.36.199.0
In addition to the above, I do moderate level of .Net development and Android. Hence you call my development machine as a MESS in true means. Because all these software stacks are installed, I cannot setup many mandatory environment parameters for Oracle products and I always manage them manually as and when required.
Warning: The below exercises are destructive. It is your sole responsibility to make backup of your existing WebLogic installation. I suggest you using 7-Zip software for making a proper backup of the WebLogic Installation “Folder”
Start 7-zip as “Administrator”, else the archiving utility will NOT able to access all files within the “WebLogic” installation folder”
Once 7-Zip GUI interface opens, browse to your partition on which you have installed the WebLogic infrastructure
Please make sure that YOU WILL TAKE A BACKUP of your installation folder regardless the time and efforts require to make it!
Once the backup is completed, you can proceed
While using WebLogic 10.3.6, I remember upgrading the forms & reports 11g Release 1 installation with R2 just by pointing the installer to the installed folder and the installation was successful without any issues. Well, stuffs have changed. If you would try to install the Fusion Middleware 188.8.131.52.0 on top of an existing 184.108.40.206.0, you will be getting a long list of errors stating incompatibility.
INST-07545: Unexpected Error.

Special Note: As usual, keep in mind, whole these exercises are done over a development environment and many of my approaches are purely non standard and doesn’t follow Oracle’s instructions. I expect you are always remembering the fair warning and not to copy the same on production environments.
Now, let us get in to the business.
Weblogic 12c 22.214.171.124 requires JDK 1.8 build 131 or later & if you have a previous version of JDK, please uninstall and install one of the recent JDK 8 releases those are available from Oracle download repos
Please download the software listed below.
JDK 8 build 172
Most of the scripts those are used with Weblogic are hard coded with the JDK path during the installation. Hence, the safest way to upgrade your existing JDK is by installing the JDK on a custom folder, for example, I always install JDK on c:\java\jdk, avoiding any release numbers attached to “jdk” portion of the folder. This guarantees that, if I upgrade to another JDK build, the path remains the same and the Weblogic scripts will NOT start screaming about missing JAVA components.
Note: While extracting the forms & reports ZIP files, make sure both the files are extracted to the same folder.
Once all the ZIP files are extracted, you should have these files in a single folder, kindly check the below image
As per Oracle’s documentation the forms installer extracts files from “setup_fmw_126.96.36.199.0_fr_win64-2.zip” when the installation is initiated. Okay, I am done with loathing Oracle for such complex installation approaches…
Install the software in the following sequence
JDK. Install and append your PATH variable accordingly. In my case, my PATH environment variable has “C:\java\jdk\bin” as the 1st entry, which is required for configuring forms and reports developers.
Fusion Middleware with forms and reports support.
D:\Downloads\Weblogic 188.8.131.52>c:\java\jdk\bin\java -jar fmw_184.108.40.206.0_infrastructure.jar
Select a new “Home” for the 220.127.116.11.0 installation as you cannot install the software on top of existing 18.104.22.168.0. So if you have had Weblogic 12c older version installed on
“D:\Weblogic\Middleware\Oracle_Home” let the new software installed on “D:\Weblogic12213\Middleware\Oracle_Home”
Follow the prompts and complete the installation.
Now, install forms and reports by executing “setup_fmw_22.214.171.124.0_fr_win64.exe” and point the Oracle home as “D:\Weblogic12213\Middleware\Oracle_Home” (Change the details as per your setup)
Both the stacks should be installed within 25-30 minutes time & you are all ready to do the upgrade.
Reminder 1: As usual, keep in mind, whole these exercises are done over a development environment and many of my approaches are purely non standard and doesn’t follow Oracle’s instructions. I expect you are always remembering the fair warning and not to copy the same on production environments.
Warning 2: The below exercises are destructive. It is your sole responsibility to make backup of your existing WebLogic installation. Things could get nasty during the upgrade process and YOU would lose all your deployments in case if you don’t have a backup. I would even suggest that you make a database backup of your WLS repo.
So far my understanding about the whole upgrade process is like following:
- Once you initiate the upgrade process for an existing 12.2.1 domain, the repository schema is updated with new information (database level)
- The deployed applications like OHS, WLS_FORMS, WLS_REPORTS binaries are upgraded to the latest version
- WebLogic startup scripts/configuration files are amended with the latest Fusion Middleware paths & references
What this means to you? Well, you will have two different Oracle Homes for WebLogic , co-existing to serve you the purpose. You cannot uninstall the WebLogic 12.2.1 or 126.96.36.199 once the upgrade processes are over ;)
In addition to the above, I believe, the whole upgrade process is intended to upgrade ONLY the server side components for the domain, not the development elements.
(Please note, I’ve reached to the above conclusion once after analyzing almost all WebLogic startup scripts and configuration files, None of the Oracle documents available as on date confirms to this findings of mine and I am the ONLY one responsible for what I just said ;) )
Let us upgrade!

I really hope, the above Oracle instructions are simple to follow & one with minimum experience setting up Oracle software should able to complete the activities without any failure.
The entire exercises should be completed within 30-40 minutes. Once the upgrade process is over, you can start the Node Manager and Weblogic Admin server to confirm the components were upgraded to 22.214.171.124.0
Mine were, so I hope you will also have the same experience.
The real dilemma starts from here. Although all the components are upgraded, none of your forms modules would load and present you the following error:
FRM-40011: Form was created by an old version of Oracle Form. This means, your forms modules which were compiled using Forms 12c 126.96.36.199.0 are not compatible with 188.8.131.52.0 & YOU MUST recompile all your existing forms/menus/libraries using the latest version of Oracle forms!
To your utter dismay, you will find that, the forms builder with your upgraded domain is NOT upgraded to 184.108.40.206.0, instead it still remains 220.127.116.11.0, which is of no use as the forms server application has already been upgraded.
This could pose different levels of difficulties while deploying the applications. I have figured out the following in my case
- I cannot recompile the forms modules to latest supported version from the same box.
- If I am developing the application on a Windows Machine and moving it to Linux environment, I will not able to compile the modules as the stack that is available with the environment will be still 18.104.22.168.0 & I am expecting to get the same “Form was created by an old version of Oracle Form” errors!
Initiate another Forms & Reports installation & choose a new “HOME” for the installation and select “Standalone forms”.
Refer this wonderful document for details, if you don’t have experience with setting up standalone forms developer instances
Add the connection details to the tnsnames.ora file available with your Standalone Forms Builder instance folder & you are all set to go. Now you can recompile the modules and go online with the supported version of forms. I didn’t check the reports part yet, I may in couple of days time & will update this post accordingly.
Well, this workaround shouldn’t be the ONLY one solution. I opted it due to the fact that I couldn’t figure out anything else and wanted to complete a migration urgently for demonstration purposes.
That’s all folks, I hope you would find the crude way of getting things done helpful in an emergency situation ;)
