• Introduction to Oracle Data Guard
  Oracle Data Guard ensures high availability, data protection, and disaster recovery for enterprise data.
• Getting Started with Oracle Data Guard
  The information in this section describes how to get started using Oracle Data Guard.
• Creating a Physical Standby Database
  You can manually create a physical standby database in maximum performance mode using asynchronous redo transport and real-time apply, the default Oracle Data Guard configuration.
• Creating a Logical Standby Database
  There are a number of steps involved in creating a logical standby database, including prerequisites and post-creation tasks.
• Using Far Sync Instances
  An Oracle Data Guard far sync instance is a remote Oracle Data Guard destination that accepts redo from the primary database and then ships that redo to other members of the Oracle Data Guard configuration.
• Oracle Data Guard Protection Modes
  Oracle Data Guard lets you set different data protection modes.
• Redo Transport Services
  An Oracle Data Guard configuration requires that Oracle redo transport services be configured and monitored.
• Apply Services
  These concepts describe how redo data is applied to a standby database.
• Role Transitions
  An Oracle Data Guard configuration consists of one database that functions in the primary role and one or more databases that function in the standby role.
• Managing Physical and Snapshot Standby Databases
  This chapter discusses the various ways that physical and snapshot standby databases need to be managed.
• Managing a Logical Standby Database
  An understanding of these concepts will help you to successfully manage a logical standby database.
• Using RMAN to Back Up and Restore Files
  You can create backup strategies using Oracle Recovery Manager (RMAN) with Oracle Data Guard and standby databases.
• Using SQL Apply to Upgrade the Oracle Database
  You can use a logical standby database to perform a rolling upgrade of Oracle Database software.
• Using DBMS_ROLLING to Perform a Rolling Upgrade
  The Rolling Upgrade Using Oracle Active Data Guard feature provides a streamlined method of performing rolling upgrades.
• Oracle Data Guard Scenarios
  These scenarios present different situations you might encounter while administering your Oracle Data Guard configuration. Each of them can be adapted to your specific environment.
