Course Objectives • Manage common targets: • Hosts • Databases • Application servers • Monitor Oracle Collaboration Suite components • Use Management Plug-ins to extend Grid Control to manage third-party products • Configure Grid Control for use with Single Sign-On and Enterprise User Security • Migrate to Oracle Enterprise Manager 10g Release 2

  20. Summary • In this lesson, you should have learned how to: • Explain the purpose of grid computing • Explain the concepts of enterprise grid computing • Describe the variety of components that make up today’s data centers • Identify the Oracle components that support grid computing • Describe the management options that are available for Oracle products • Describe how Grid Control provides a single point of management for your data center

  21. Grid Control Architecture

  22. Objectives • 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 • Describe the possible High Availability configurations

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

  24. E-Biz Host AS ……. Oracle Management Services DB Agent Servers Storage Network Software AS OCS E-Biz Database Enterprise Config Management Application Perf Management E-Biz Host AS ……. Precision System Monitoring Administration DB Agent Infrastructure (Jobs, Alerts, and so on) E-Biz Host AS ……. DB Agent Grid Control Components Targets Manage from Anywhere HTTP/S HTML Console HTTP/S Mobile device JDBC HTTP/S HTTP/S Oracle Management Repository Portals Firewall

  25. 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

  26. 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
