Hi,
As per the logs
Library 'D:\usr\sap\BQ1\DVEBMGS00\exe\dboraslib.dll' loaded
B *** ERROR => Version mismatch between kernel (721.02) and DBSL shared library (720.00)
[dbcon.c 5450]
M ***LOG R19=> ThInit, db_connect ( DB-Connect 008192) [thxxhead.c 1497]
Could you update the kernel is not synchronized between DVEB*/exe and /sapmnt/SID/exe
Please synchronize the same and start the system manually.
Hope this helps.
Regards,
Deepak Kori
