I tried using /s switch withe the OM 3.8.1 installer as below:
Though the application is installed, but it fails to comple many of the installation tasks as below: (The tasks below are performed while installing the application manually with a valid license key -it's a snap of the installation log that is created by the OM installer in installation folder)
Setting up services... Setting up sql ... Starting SQL ... Setting up DBA user ... Setting up transaction log management... Defining SQL schema ... Defining SQL Views ... Defining SQL debug procedures ... Setting up DFM user ... Creating or updating sample backup schedules and throttles. Stopping SQL ... Enabled Operations Manager license. Installing help files... Starting service... Service: sql started. Service: http started. Service: eventd started. Service: monitor started. Service: scheduler started.
Service: server started. Service: watchdog started.
Among all these things, some are very critical. So it seems dificult to go for silent installation
