Monitoring RAC with Grid Control

 To use Grid Control to monitor RAC all you need is the login username and password (established when the Grid Control was installed) and a valid web browser (Internet Explorer, Netscape or Mozilla). You enter the address of the Grid Control portal and the main Grid Control login screen is invoked (Figure 9.3).

Figure 9.3: Grid Control Login

The standard address for invoking Grid Control is:

http://oms_servername.com:7781/em/

The port 7781 is the standard port although there are also secured versions of the screen which use https and port 7779.

Once you have successfully logged on to Grid Control the top level Grid control screen is displayed. This top-level screen is shown in Figure 9.4.

Figure 9.4: Grid Control (Top-level Enterprise Manager)

From the top level screen you use the mouse to click on various controls (specifically under Targets) to get to the cluster database screen. The cluster database screen will be used whenever you select a target that is part of a RAC installation. The RAC cluster screen shows all instances, their status and any alerts that pertain to the currently selected cluster database. This screen is shown in Figure 9.5. In this screen, at the bottom of the page, 4 nodes supporting the cluster database "AEPRD" is shown. It shows the policy violations, memory utilization and I/O activity. Thus, you get to see a unified image of the activity within all the nodes of the RAC architecture.
