SUM 16 best runs in IE 10 and above, and also you need to update the JAVA to the latest version.
To start SUM,
Follow the below steps.
1. Go to location of SUM
2. With root user Run command ./STARTUP confighostagent <SID>
3. Open internet explorer on terminal server
4. Then https://<hostname>:1129/lmsl/sumabap/<SID>/doc/sluigui
5. It will give you logged in screen. Log in as user SIDADM
6. You will be able to start SUM.
Thanks
