Hi,

On my Targets Page in OEM, i can see that some of my Management Agents are unreachable. When i try to check the status it gives a timeout error as below;

# emctl status agent
Oracle Enterprise Manager 12c Cloud Control 12.1.0.1.0
Copyright (c) 1996, 2012 Oracle Corporation.  All rights reserved.
---------------------------------------------------------------
Status agent Failure: Timed out after 300 seconds


Also tried Stop/Start of the agent to no avail;

[oracle@lxx0485:/prd/dvp/ora/app/oracle/product/12.1.0/Middleware/agent/core/12.1.0.1.0/agent_inst/bin]# emctl stop agent
Oracle Enterprise Manager 12c Cloud Control 12.1.0.1.0
Copyright (c) 1996, 2012 Oracle Corporation.  All rights reserved.
[oracle@lxx0485:/prd/dvp/ora/app/oracle/product/12.1.0/Middleware/agent/core/12.1.0.1.0/agent_inst/bin]# emctl start agent
Oracle Enterprise Manager 12c Cloud Control 12.1.0.1.0
Copyright (c) 1996, 2012 Oracle Corporation.  All rights reserved.
Agent status could not be determined.  Check the agent process



Could you please tell me what are the troubleshooting steps that i can try?

Thank you

root cause & fix are external to Oracle
Oracle is the victim; not the culprit.
