I have stopped SUM, sap on primary, shadow instances & regenerated the password file by using below command.
dscdb6up -create <connect_user password> <sidadm password>
Replaced the Kernel present in /usr/sap/OS2/SUM/abap/exe with the latest target release kernel available from service market place.
I tried to restart SUM but no luck.
I tried to start shadow instance manually, but failed with below error
ri3pa043:os2adm 10> cd /usr/sap/OS2/SUM/abap/bin
ri3pa043:os2adm 11> ./SAPup startshd
Starting shadow system ...
Starting service ...
FATAL ERROR: Process /usr/sap/OS2/SUM/abap/exe/sapcontrol exited with 2, see '/usr/sap/OS2/SUM/abap/log/SAPup.ECO' for details
I am attaching DEVTRACE.LOG, STARTSSC.LOG from /usr/sap/OS2/SUM/abap/log & dev_w0 from /usr/sap/OS2/SUM/abap/system/OS2/DVEBMGS02/work.
Can someone please check the logs & help me.
