Chapter 9 -Managing and Using Oracle Grid Control

Grid Control 

Grid Management Server needs to have Oracle Database as its repository where the variety of collected data is stored, analyzed and used for threshold monitoring etc.  After setting up the Grid Oracle Enterprise Management Server (OMS), Grid Agent software has to be installed on the chosen target. While installing the agent software, you need to specify the Grid OMS server to which it communicates.

Figure 9.1 shows Grid Management Server and the agent architecture

Installation of Grid Control Server and Agent

Oracle Enterprise Manager Grid Control (OEM Grid Control) includes the Oracle Management Agent, Oracle Management Service, and Oracle Management Repository, as well as the Grid Control Console, a browser-based central console through which administrators can perform all monitoring, administration, and configuration tasks for the enterprise.

After ensuring that you have installed and configured the Grid OMS in the network, install and configure the Agent on the RAC nodes. We show an example of installing the Grid Agent software and connecting the Grid OMS. The System or Host where agent is installed is called a Target System. Besides the host itself, the resources like Database, Application Service, Web Application, and Listener running on the host system also become the targets for the Grid OMS. First install and configure the OMS and then install the Agent on the target hosts.
