Oracle Data Guard- An Overview

Oracle Data Guard consists of a production database and one or two standby databases. The databases in Data Guard configuration are usually connected by Oracle Net and they can be dispersed geographically. There are not any restrictions on the location of the databases if they are able to communicate with one another. For instance, you may have a standby database with the production database together with two standby databases at remote locations. You can manage primary as well as standby databases using an SQL command-line interface or a Data Guard broker interface including graphical user interface and a command-line interface.

  • Primary Database : A Data Guard configuration has one production database, known as the primary database that functions in a primary role. This database is accessed by many of the applications. This database can be either an Oracle Real Application Cluster or a single-instance Oracle database.
  • Standby Database : A standby database is a consistent copy of a primary database. By using the backup copy of a primary interface, you will be able to create thirty standby databases and then incorporate them in Data Guard configuration. Once you create it, Data Guard maintains every standby database automatically by transferring redo data from a primary database. Just like a primary database, standby database may be either a single-instance database or an Oracle RAC database.

The standby databases are of the following kinds:

  • Physical standby database – It offers a physically identical copy of a primary database. The database schema such as the indexes are the same. A physical standby database may receive and apply redo when it is open.
  • Logical standby database – It has the same logical information just like the production database through the structure and physical organization of the data are different. A logical standby database is synchronized along with the primary database via SQL.
  • Snapshot standby database – It is a completely updatable standby database. Just like a logical or physical standby database, it archives and receives redo data from the primary database.
