Hi Vinay,
Did this happen after you installed it or has this been running fine and then you just noticed this extra instance in the GUI? Double check the metric tree and see if both instances are identical.
If you are seeing one extra node there are a few reasons for this.
1. You may have another agent instance using the same profile setup running on the same server.
2. Your application may be spawning off another process which is being picked up by our agent.
3. Your agent may have been restarted or restarting too quickly before the EM realizes it has disconnected.
Are you using windows or linux?
If windows, open up task manager. Make sure that you add Command line and PID to the list of columns to view in here. Sort by name and see where java.exe is coming from. Double check
If linux, perform the same using ps -ef | grep java
This may show two different paths or same path but different process name, i.e. your app could be named Medrec but it may be spawning off another process named ContactDomain or something like that.
If however you only see one weblogic process per above, then you would need to check the agent logs to see if there were any disconnects and reconnects in a short period of time.
You could also try stopping weblogic, wait until both instances go grey in the GUI and then start it up again. If both show up, then its most likely another process being spawned off in the same java process. From here you would investigate your startup script for weblogic, generally named startWebLogic.cmd or startWebLogic.sh depending on your OS.
Thanks,
Matt
