Can't connect to X11 Windows Server - Error

Dear All,

Greetings!!

We had successfully installed ECC6.0 EHP7 with HANA Database on SUSE 11 SP3. Now we are in the process of upgrading the components in the ECC via SUM. When we try to start the upgrade via SUM using <SID>ADM userid in the Linux Machine, we are getting an JAVA Error like "Can't connect to X11 Windows Server". Please find the complete error log in the attached screenshot (SUM.pmg).

But when we try the same with the root userid, we can able to see the SUM GUI Opening Screen.

Please help us with suggestions or solutions at the earliest.

Regards,

Ela

    How are you starting the SUM tool ?

    You can start the SUM tool but executing the STARTUP script in the background and then use a browser to access the tool using the URL http://localhost:4239

    But if you want DISPLAY to be set then what is the output for xclock ?

    su - sidadm

    xclock

    Regards

    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
