Yo u set the ti me at which the background ob should start, !t speci"ied intervals the background scheduler checks i" there are any background obs to be processed. #!P background processing automates routine tasks and helps you optimi$e your organi$ation%s #!P computing resources. &nteractive users have the system during the day, large background obs have the system by night.
