Hi Reagan,
If you mean I need to start the shadow instance under folder /usr/sap/<SID>/upg/abap/bin use the following command: SAPup startshd,
then yes i have tried but failed with the following error:
FATAL ERROR: Process 'sapcontrol' exited with 1, see '/usr/sap/S01/upg/abap/log/SAPup.ECO' for details
I've tried this in the first place.
Thank you!
Best Regards,
Carina Hu
