Hi Marvin,

Please set display variable using using export or setenv.

Then run xclock. If this is opening a clock window then your display is set and you can start SUM.

Other wise set the variable correctly as per your OS and shell.

If even after setting this is not working, check for X11 rpm is installed on your system.

If not get this installed from your OS team.

Regards,

Divyanshu

Hi Divyanshu,

you're right, afer i set the env, the SUM Gui shows up.

thankyou.

i'm trying to export the Certificate to fix the error at SUM when i try to run it.

but when i export it, it says like this :

<localhost>:<sid>adm 56> sapgenpse export_own_cert -v -p /usr/sap/<SID>/DVEBMGS00/sec/SAPSSLS.pse -o /sapcd/SUM/solman.crt

Opening PSE "/usr/sap/<SID>/DVEBMGS00/sec/SAPSSLS.pse"...

No SSO credentials found for this PSE.

PSE (v2) open ok.

Retrieving my certificate... ok.

Couldn't open output file /sapcd/SUM/solman.crt

is there something that i missed ?

Regards,

Marvin
