Oracle10g Real Application Clusters (RAC)          

Duration: 3 or 5 days

This class will introduce experienced Oracle DBAs to Oracle10g Real Application Clusters (RAC). Students will work with the available tools used to configure and manage the RAC environment. This will cover design considerations for a RAC environment on different platforms. This class will cover setup and configuration for an Oracle10g RAC environment. Backup/Recovery, monitoring and tuning issues for a RAC environment will also be covered. This class is ideal for an organization that is considering or preparing for a migration to the Oracle 10g Real Application Clusters platform.
