Re: Can't connect to X11 Windows Server - Error

Hello Ella,

Please follow the SUM upgrade guide for starting the SUM tool.

Start the SL controller on primary application server with command :
./STARTUP

After this, you can access the GUI from the browser :
http://<host>:4239/

Problem you described, seems to be related to variables.
Please set the variable DISPLAY for the SIDADM user.

Thanks.

Regards,
Gaurav
