Oracle Apps in Windows 8

Just recently I started using windows 8 Consumer Preview and found all my Oracle related software and application process are running smooth. If not still I have the option to install the software in compatibility Mode.

Toad 9 & 11

Forms & Report 6i

Jdeveloper

BI Publisher

Oracle Database Server 11g

Oracle Application Forms Screen 11i & R12

Do not update your JRE version to 7 if you are using Internet Explorer 10 in windows 8. This will give you hell a lot of problem when you open Oracle Application Forms screen.

So far things seems to be good and will keep you posted if I encounter issues.

Fell free to upgrade your OS to Windows 8 it gives a bit of new experience.

ERROR 1723 - Java Error

Error 1723: Can not uninstall JRE update 1.6.9.21 from Windows 7 or Windows 8. I got this error after JRE 7 update. I was unable to open Oracle Application forms screen in R-12 instance.

Previously I have faced such issues and after long research and several trial and error methods, I have reinstalled my OS to fix the corrupt missing files - "but not this time"

Java Runtime Environment or Initiator will call the system stored dll files to open the Oracle forms screen. JRE 6 is the certified version with Oracle Forms Application when you update JRE 7 your jinitiator version stored in your system will not match with the jinitiator stored in the server from where you will be calling the run time environment files, hence you will get "You have a lower version of jinitiator you will have to upgrade to a latest version of the jinitiator",  but to do that you will have to remove the JRE 7 update and will have to manually install JRE 6 update.

If you try to install JRE 6 your system will give you error stating that you cannot install this version as a copy of this version already exists in your system and the will ask you to remove the update.

You should be very careful when you remove Java updates as these will leave a Trace deep in your system that will become a mess if you will be trying to install or remove JRE updates.

Try to remove the updates through the standard windows Add and Remove program that is available through your Control Panel or check for the JAVA in your control panel and you can remove it. But occasionally if you have deleted the Java files from the C:/Program Files system will nor allow you to remove the JAVA from the control Panel add and remove programs in such coactions you will have to go to REGEDIT

Incorrectly editing your registry may severely damage your system. At the very least, you should back up any valued data from your computer before making changes to the registry.
You can use the File->Export functionality of the registry editor to save the registry key before deleting. Then, in case you deleted the wrong registry key, you can restore the registry from your saved backup file, by using the strong>File->Import functionality in the Windows Registry Editor.

Steps to Edit/Delete Java registry entries through Registry Editor

1. Run the Windows Registry Editor by clicking Start->Run and entering the program name regedit in the Open edit field.
2. Navigate to the following registry node:
   HKEY_LOCAL_MACHINE/Software/Microsoft/
Windows/CurrentVersion/Uninstall
   
   
3. Under this Uninstall node, you will find many registry entry names enclosed in curly braces. e.g. {26A24AE4-039D-4CA4-87B4-2F83216013FB}
4. Click on each registry entries in the left pane and that will display its associated data on right pane of Registry Editor.
   or
   Click on Edit->Find tab in Registry Editor window and then enter Java version that you want to find Keys for
   For example: searching for Java(TM) 6 Update 24 finds this:

5. Delete the registry entry found for Java, by right clicking on the registry key name, and selecting Delete.
6. Click Yes on the Confirm Key Delete message box.
7. After you finish above steps, go back to the Windows Control Panel
   For Windows XP: Add or Remove Programs
   For Windows 7: Uninstall programs
   The entry for Java should no longer appear.

After performing the above steps you will remove java completely from the system but this will remove all the required DLL files that has to be in the system to support Java installation. Its a easy way to restore the same is to copy the JAVA files from other system where jinitiator is running fine. Once your JAVA files with the BIN folder are there in the system Program Files the system will allow you to install required version of JRE updated to work with.

Now you will have a commanding feel

"System should do what I say if not I will fuck its registry the hard way it dose what I say"
