Starting OBIEE 12c from Command Prompt

You can directly start the OBIEE 12c services by going to the Middleware home folder and to the path below, 

Oracle_FMW/user_projects/domains/bifoundation_domain/bitools/bin

Now open a command prompt window, Shift + Righ Click and then type the filename start.cmd. This will start the execution of OBIEE 12c services. 

Alternatively you can run each component individually as it was done previously for OBIEE 11g.
