However when I try to access the above link I am unable to launch the frontend, I get the below error:

The XML page cannot be displayed

Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.

---

XML document must have a top level element. Error processing resource 'http://hostname:1128/lmls/upgrade/T6...

One more thing to be noted that I cannot see the SAPup process running at OS level.

Any idea what could be wrong here, I am unable to find any other error in logs.

Hello Kumar Avi,

please read the DMO documentation carefully:

• you have to create an configuration file for SAP Host Agent:
  "SUMSTART confighostagent"
• this way the SAP Host Agent will start SAPup when you send the browser request
• you do NOT start SAPup (or startup batch) manually on the console for DMO

Hi Boris,

Thanks for your reply, we had already run SUMSTART confighostagent however we still faced that issue.

We were doing this on a cloud system, once we restarted the issue got resolved.

Not sure what was wrong but it worked .

Thanks

Hi Kumar ,

Even i faced the same issue . this is how i solved in my situation .

restart the sap hostagent by going to its directory

Linux:    <HOSTAGENT directory>/exe/saphostexec -restart

Windows:     <HOSTAGENT directory>\exe\saphostexec -restart

launch the DMO using the below link after running SUMSTART.BAT

url : http://<HOST NAME >:1128/lmsl/sumabap/<SID>/doc/gui/

Regards,

Victor
