DB Console EMAGENT process is still running

Issue:

I see that the EMAGENT process is still running , even after i shutdown the DB Console. It is writing XML logs in the "upload" directory. I tried to shutdown the agent using command "emctl stop agent", but the command is not working.

 Solution:

Due to various reasons, such as crashing, incorrect configuration, corrupted memory or process termination, the DB Console processes may be left over in an undetermined state making start/stop operation failing.

 Below are 3 main processes for DB Console:
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)

Here I manually cleared the agent process
