Chapter 9 -Managing and Using Oracle Grid Control

Managing Target Groups

In order to effectively manage such large sets of targets, you typically need to do the following:

• Obtain the status of critical system (e.g. are there any critical alerts in databases of NY
   

• Perform batch operations against all members (e.g. backup all my London databases every week)
   

• Define and configure monitoring of all  systems
   

• Compare Performance metrics of different groups of databases

 The Enterprise Manager framework supports these classified types of logical entities called 'groups' and then performs operations against them as a group. There are two types of groups supported: Oracle-defined groups and user-defined groups. Examples of Oracle-defined groups are: Database Real Application (RAC) Clusters, Stand-Alone Databases, Hosts and Application Server Clusters etc.

Grid Control provides a predefined set of management operations with each Oracle-defined group. For example, the Enterprise Manager console provides a RAC cluster home page which gives you a big picture view of the status of all instances in the RAC, as well as a summary of all open database and instance-level alerts. From this RAC home page, you can access real-time performance charts and perform instance-level as well as database-level operations.
