We are using Oracle applications R12 12.0.6 with JDK 6.0 while most of the clients are using JRE 7/8 based on different business requirements (With full knowledge that there would be unexpected results due to the compiled versions). We’ve observed a peculiar issue with the JRE applet once after the upgrade to Windows 10 version 1803. The Java applet started showing too small fonts while launched from displays with high DPI resolutions.
Digging in brought me to the following discussion:
Although there are multiple recommendations, for EBS environment, Please follow the below instructions:
Launch the JAVA applet by opening a forms based module.
Open task manager and locate “Java(TM) Platform…”, right click and open properties. This will open the properties for “jp2launcher.exe”. Click on “Compatibility” and click on “Change high DPI settings”. Now check “Override high DPI scaling behavior. Scaling performed by:” to “Application”. Refer the image for more details.
Once the changes are made to the properties of the executable, restart the box. It could be specific case, the changes were not applied until a restart for me.
Although it fixes the font scaling issues, the toolbar area of the Oracle forms are remains scaled with pretty small icons. I am yet to find out a fix for this minor annoyance. May be quite soon.
