  • After completing this lesson, you should be able to do the following:
    • Describe the Grid Control architecture
    • List the components of the Grid Control framework
    • List the types of targets that are manageable by Grid Control
    • Use the Grid Control console

grid control components
Grid Control Components
  • Oracle Enterprise Manager 10g Grid Control comprises three major components:
    • Oracle Management Repository
    • Oracle Management Service (OMS)
    • Oracle Management Agent

managed targets
Managed Targets
  • Managed targets may include:
    • Oracle databases
    • Oracle database listeners
    • Oracle application servers
    • Oracle applications
    • Oracle Collaboration Suite
    • Oracle E-Business Suite
    • Most operating systems that are certified to run Oracle products
    • Third-party products and applications
oracle management agent
Oracle Management Agent
  • Oracle Management Agent:
    • Must be installed on each managed host
    • Must be in its own ORACLE_HOME (unless usingNFS-mounted agent)
    • Communicates with OMS via HTTP or HTTPS

Oracle Management Service
  • Oracle Management Service (OMS):
    • Includes member components:
      • Oracle HTTP Server (OHS)
      • Oracle Application Server Containers for J2EE (OC4J)
      • OracleAS Web Cache
    • Is a J2EE application deployed on Oracle Application Server 10g
    • Connects to Oracle Management Repository by using Java Database Connectivity

Management Repository

oracle management repository
Oracle Management Repository
  • Oracle Management Repository:
    • Resides in an Oracle database
    • Includes schema objects belonging to SYSMAN
    • Can be installed in a preexisting database
    • Can be installed in a RAC database
accessing the grid control console
Accessing the Grid Control Console
  • The Grid Control console may be accessed by any supported browser:
    • Netscape Navigator 7.2
    • Mozilla 1.7
    • Firefox 1.0.4
    • Safari 1.2
    • Microsoft Internet Explorer 6.0 (SP2)
      • http://<oms hostname>.<domain>:<port>/em
      • http://omsserver.mycompany.com:7777/em
managing very large grids
Managing Very Large Grids
  • The Grid Control framework uses the Oracle 10g technology stack. For large grids with many administrators, the Grid Control framework scales well.
    • Oracle Management Repository can be installed in a Real Application Cluster.
    • OMS can take advantage of Oracle Application Server 10g clustering.
high availability configurations
High Availability Configurations
  • The architecture for deploying Grid Control in a highly available fashion is based on two key concepts:
    • Redundancy
    • Component monitoring
