Oracle10g Grid Computing with RAC
Chapter 9 -Managing and Using Oracle Grid Control

Managing Target Groups

For demonstration purposes, let us create a group called MYDBGROUP with three NY development databases where there is a mix of stand-alone and RAC databases. Then we will define some sample metrics for the monitoring purpose as shown in the next screen (Figure 9.20). There are seven metrics defined as shown below:

Figure 9.20: Creating a Group to manage as one entity

 From the Home page of the group "MYDBGROUP", click the tab "performance" to display the activity of the metrics collected. Metrics information is shown in the next screen (Figure 9.21).

 In another example, for the target group called Dev. Service where there are five instances and wait time is shown for all of them in a single display. This helps to have a quick comparison of the activities of all the instances within a group of targets.

Figure 9.21: Group of 5 instances monitoring the wait Time (%)

In another example, a group of targets containing an application server and database is compared in a single display.

Figure 9.23: Metrics for various targets are shown together
