thanks for your Reply..
1.When we go to Service Center Factory-Espace (selecting the espace) we have a button Download Published Version.By Clicking the button we get oml file.so again we go to the Destiniation system or server we should open that oml file in service studio then click 1 click deploy for deploy the application in server.
Is it Correct Flow ?
2.there is no Entites refrence for the application in Server.So i go to Configuration tool screen change server and [from the default "Outsystem"] catalog name where the entities exist to connect the sql database.In these case we get error like they search the sys_parameter etc. file in that catalog.
Please give the flow of executing the application on server using the Existing DB in details.
