Hi Team, I m quite new to 10g n its oem. One of the machine is running OEM in my organization and we are seeing everything down on the same machine. OEM is running fine for other machines n Databases. for that machine processes we are getting "The agent of this target is unreachable.<http://dnlvnjtools:4889/em/console/monitoring/availOverview$type=oracle*_emrep$pageType=byDay$target=Management_20Services_20and_20Repository> " Agent shows its already running on that machine. Which parameter needs to set for resolving the problem. Regards - Chirag
