Standard output of script_out_<date>_<time>.log contains these 5 lines :
Changed database context to 'mdb'. Changed database context to 'mdb'. Changed database context to 'mdb'. Changed database context to 'mdb'. Changed database context to 'mdb'.
But in some SQL Server configuration, "changed database context to" are not displayed. So it could be normal that file script_out_<date>_<time>.log is empty
To check if SQL Script Patch_sqlscripts.sql has been executed successfully, execute following SQL Query :
select * from statjobm
and check if column auto_rep_version is present
