Oracle Management Agent 10g был установлен на узле с помощью скрипта agentDownload script. Несмотря на то, что установка и настройка агента прошла успешно, новый узел не появился в списке хостов в веб-интерфейсе Enterprise Manager Grid Control.
Статус агента:

Agent is Running and Ready
В статусе агента видно, что Агент не может загрузить данные в OMS, а если вручную попробывать загрузить данные, то выводит такое сообщение:gc@agenthost $ emctl upload

EMD upload error: uploadXMLFiles skipped :: OMS version not checked yet..
В логах агента, нашла такие ошибки в ORACLE_HOME/sysman/log/emagent.trc:2008-04-23 19:54:26,063 Thread-20 ERROR http: snmehl_connect: Failed to get address for omshost: Non-Authoritive Host not found (error = 2)

Причина ошибки оказалась простой, из узла agenthost не определялся omshost:
gc@agenthost $ ping -a omshostПосле, прописания omshost в /etc/hosts (555.555.555.555 omshost), загрузка данных в OMS прошла успешно
ping: unknown host omshost
Теперь в статусе агента видно, что загрузка прошла успешно:
gc@agenthost $ ping -a omshost
omshost (555.555.555.555) is alive
