Middleware agent is not running.

Check to see if the middleware processes are running. To do this, log into the middleware machine, and run "ps -ef | grep 3566" to see if any processes are running.

To restart the middleware agent processes, please use these steps:

If the middleware machine is Unix/Linux:

1) cd <install_dir>/agents/bin
2) ./quest_launcher_daemon shutdown
3) ps -ef | grep 3566 (kill any remaining procs)
4) ./quest_launcher_daemon start

If the middleware machine is Windows:

Go to Control Panel  | Administrative Tools  | Services and restart the "QAM launcher 3566" service.
