Goal

Due to various reasons, such as crashing, incorrect configuration, corrupted memory or process termination, the Enterprise Manager Database Control (DB Console) processes may be left over in an undetermined state (not under process control) making start/stop operation failing.

For a running DB Console, there are 3 main processes:

1. "emwd.pl dbconsole"
    Called EM WatchDog process, this one is controlling all the other ones.
2. "emagent"
    This is the EM agent process, parent PID is the WatchDog one above.
3. "java"
    This is the DB Console process it self (the UI console, OMS, etc...). Parent PID is also the emwd one (WatchDog)
