Hi Guna,
Were you able to solve your shadow istance not starting problem?
SAPup startshd
Starting shadow system ...
Starting service ...
FATAL ERROR: Process /usr/sap/SID/SUM/abap/exe/sapcontrol exited with 2, see '/usr/sap/SID/SUM/abap/log/SAPup.ECO' for details
I too have the same error. Please let me know what you have done.
Thanks.
Ramesh.
