HI Tapan,
My system is a dual stack, so the value for admin/user/<SID> would be 'j2ee_admin' by default
I believe for single stack system, it will have the default value of 'administrator' as you mentioned
Yes, SUM will change it to SAP* during downtime, after it is done, SUM will restore back to the original UME.
its just weird that during 5.5 Execution, it detects a wrong password.
Best regards,
Alex Lee
Additional information
* Taken from 5.3 Configuration phase of SUM tool
The update reconfigure user management engine (UME) so that only the SAP* user can access the system. The SAP* user is only active during the downtime phase of the update. The update program deactivates it after the downtime phase has finished and restores the original UME configuration.
