EMD upload error: uploadXMLFiles skipped :: OMS version not checked yet.

I strongly believe if you’ve deployed agents a coupled of times, you’ve encountered the following error after the installation:

[oracle@dg2 bin]$ ./emctl upload agent
Oracle Enterprise Manager 10g Release 3 Grid Control 10.2.0.3.0.

EMD upload error: uploadXMLFiles skipped :: OMS version not checked yet..

The first thing that should be done is checking the log file. Switch to the following directory and tail the log file:

cd /u01/oracle/product/10.2.0/agent10g/sysman/log
tail -f emagent.trc

Here’s the output from the log file:

2012-07-26 03:46:33 Thread-51022736 ERROR pingManager: nmepm_pingReposURL: Did not receive a response header from repository
2012-07-26 03:47:08 Thread-51022736 ERROR pingManager: nmepm_pingReposURL: Did not receive a response header from repository
2012-07-26 03:47:08 Thread-51022736 ERROR pingManager: nmepm_pingReposURL: Did not receive a response header from repository

I checked the status of the agent and saw that it’s running :

So I decided to clear unnecessary files that can’t be uploaded to the Grid Control under the following directories:

$AGENT_HOME/sysman/emd/collection

$AGENT_HOME/sysman/emd/state

$AGENT_HOME/sysman/emd/recv

$AGENT_HOME/sysman/emd/upload

$AGENT_HOME/sysman/emd/lastupld.xml

Then stopped the agent, secured it, cleared unnecessary files again with clearstate parameter, started the agent and uploaded.
