Hi Ravindra,
hopefully you have installed the Database Configurator and the Database Scripts component together with the rest of your installation.
Unfortunately the Trial version does not see have UI for the Database Configurator so you will have to use the CLI version of it.
Usually these components are located under common/db where you have installed your wM Trial version.
go to the bin subdirectory for the program and go to the scripts subdirectory for the scripts separated by db vendor types.
See Database Configuration Users Guide for further information.
Regards,
Holger
