Error:

Caused By: oracle.apps.fnd.oam.em.sdk.targetData.discovery.AppsDiscoveryException: Fail to get EMDClient for Host hostname

Caused By: java.sql.SQLException: ORA-01403: no data found

ORA-06512: at line 1

Cause:

Hostname lacks domainname

Solution:

Step 1.  Bounce the Agent.

Step 2.  Create a backup copy of AGENT_HOME/sysman/emd/targets.xml.

Step3. Edit targets.xml and change the host property from hostname to hostname.domainname

Step4. Start , upload the agent and redo the discovery.

If this doesn’t work , you can restore the targets.xml.

However,  you can change the host property of an agent through emcli utility . It will not create the duplicate entry.

How to setup emcli:
