SAP Startup error after kernel upgrade

Hi

I have upgraded to kernel 700 patch 278 but unfortunately after that system is not getting up. Database is

started successfully but R3trans -d is giving following error.

ERROR => CONNECT failed with sql error '1005'

ORA-01005: null password given; logon denied

After that to troubleshoot I reverted the kernel upgrade to older version 700 sp 185 then system starts successfully.

Please see attached trans.log

Please suggest in this.
