EMD upload error: uploadXMLFiles skipped :: OMS version not checked yet..
如果报以上错误，则说明agent不能uplaod文件到OMS服务器 $ emctl stop agent
- delete all files in $AGENT_HOME/sysman/emd/upload - delete all files in $AGENT_HOME/sysman/emd/state
$ emctl clearstate agent (this should delete all state files but sometimes it is not enough, but I experienced that it is better to use this command after deletion of the files) $ emctl secure agent (and specify the password on demand) $ emctl start agent
