This post covers installation of Oracle Enterprise Management (OEM) Grid Management Agents on Machine which you are planning to monitor using Oracle Enterprise Manager Grid Control.
What is OEM Grid Control Management Agent ?
Management Agent is software installed on node (machine) which you are planning to monitor. Agent collects information on target node (Host, Database, Listener, Application Server …) and transports that information to Oracle Management Service(OMS) which inturn pass on that information to Management Repository (Oracle Database).

Installing OEM Grid Management Agent
There are various ways of installing agent on Nodes (which you wish to Monitor using OEM Grid control)
i) AgentDeploy Application – requires SSH, sudo access to run root.sh on remote target Node
ii) nfsagentinstall Script– limitation is one agent installation at a time, not supported on clusters (RAC databases) and for OCFS file system. requires SSH, sudo access to run root.sh on remote target Node
iii) agentDownload Script – Download script from console is available from 10.2.0.5 version. For previous version download from here
iv) using Oracle Installer (OUI – Oracle Universal Installer)
i) AgentDeploy Application– useful for installing multiple Management Agents (mass deployment) remotely. AgentDeploy application connects to OMS (Oracle Management Service), copies files scripts required for Agent to target node and then run them to install Agent on remote Node.
To Use AgentDeploy Application – Login to OEM Grid Console -> Click Deployments -> Click Install Agent
ii) nfsagentinstall Script– software to install Management Agent is shared on remote nodes using NFS. To start Management Agent installation using this menthod execute script ./nfsagentinstall -s <EMSTATE Directory location> -p <port number>
iii) agentDownload Script– This method uses pull technology, run agentDownload script from target node. This script creates directory for Agent Software, downloads response file from OMS (Management Server) Web Server and starts installation of Management Agent in Silent Mode.
iv) using OUI– This method of installing Oracle Management Agent uses Oracle Universal Installer (OUI). Start Installer , when prompted for “Installation Type” select “Additional Management Agent” .
