in appserver there should be a process named appsvc. when a job started to executed it generally runs with rscd privilege so you can see a process with rscd,bltargetjobmanager, bldeploy (in case of deploy job) and deployment or application specific process in case of application deployment.
e.g. in case of ms-sql deployment you may see a process running with setup32.exe
Your query is looks like an open ended question. Could you specify an exact scenario here.
