No. I have not tried this on Windows 11. However, I have recorded video for Windows 2019. Below is the link. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jE0r7PRC6ZA.html
OEM is a resource heavy application and it needs high number of cores with minimum 12GB memory. In my personal setup, I have to issue the OEM startup twice as it always fails first time. So this is common.
Already do that steps, but log says the same, "INFO: oracle.sysman.top.oms:Still Running..." repeatly. even I've been waiting for more than 3 hours. FYI, The Repository i using oracle 19c and the oem i already try 133 and 135. but give me the same.
