Oracle Enterprise Manager Cloud Control is a
very handy tool to monitor database servers. Sometimes it happens that Cloud
Control does not show the actual status of a target. If status of your database
is either “Pending” or “Metric Collection Error”, you can try following trouble
shooting steps to resolve the problem. Similar steps may also be followed if
targets other than database targets face same issue.
Check the agent status and unlock the agent if
it is locked. Once unlocked, click on the agent to go to agent’s home page and
then form “Agent -> Synchronization”, do agent synchronization.
To be on a safer side, try
stopping and starting agent along with the above step. From target host, issue
following
$AGENT_HOME/bin/emctl
stop agent
$AGENT_HOME/bin/emctl start agent |
Another step you may try is to refresh
monitoring configuration. Go to target home page and then “Target setup ->
Monitoring configuration
Click on “Test Connection” to check if
connection is working fine, and then click OK.
Click OK on the next screen
Hopefully target would be showing “up.
