If you are using Reports Server as an in-process Reports Server (the default configuration), sending a run report request starts the in-process Reports Server. However, if you are sending a request through a command line, Oracle Reports Servlet (rwservlet) must be started first using either the run report URL or the Web command URL. When you have successfully started rwservlet, you have successfully started the in-process Reports Server.
To directly start or stop the in-process Reports Server using a URL, enter the following in your Web browser:
http://machine_name:port/reports/rwservlet/startserver http://machine_name:port/reports/rwservlet/stopserver
