Hi Sri,
goto SUM/abap/bin
Run SAPup set shdddicpwd
and share the result.
If it is
ERROR in GUI communication: Empty XML file
FATAL ERROR: Empty XML file
Then the problem is with DDIC password.
Else,
Share results of
sapcontrol -nr 61 -function GetSystemInstanceList
Also share SAPup.ECO.
Regards,
Divyanshu
