Shadow instance start up failed during upgrade preprocessing

Dear All,

We are upgrading our SAP R/3 4.7 to ECC 6 EHP7. O/S is AIX 6.1 and database is Db2 9.1 FP10.

We are getting following error during upgrade pre-processing .

Severe error(s) occurred in phase MAIN_SHDPREPUT/START_SHDI_PREPUT!

Last error code set: Shadow instance couldn't be started, check 'STARTSSC.LOG' and 'DEVTRACE.LOG': Process /usr/sap/OS2/SUM/abap/exe/sapcontrol exited with 2, see '/usr/sap/OS2/SUM/abap/log/SAPup.ECO' for details

Belog is the log from /usr/sap/OS2/SUM/abap/log/DEVTRACE.LOG

output of the command setenv


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.

Thanks,

Vinay
