Replicating Data With Oracle Data Guard Software

Chapter 1

This chapter describes how to configure data replication with Oracle Data Guard software in an Oracle Solaris Cluster Geographic Edition (Geographic Edition) environment.

This chapter covers the following topics:

This release of Geographic Edition supports the Oracle Data Guard Physical standby type and the Logical standby type. The Snapshot standby type is also supported when an Oracle 11g or 12c database is used.

Geographic Edition software supports the use of Oracle Data Guard for data replication when used with HA for Oracle or Oracle Real Application Clusters (Oracle RAC) software.

Note - A minimum of the Oracle Solaris Cluster 3.3 5/11 version of the HA for Oracle data-service software is required for support with Oracle Data Guard. In addition, the SUNW.oracle_server resource type that is used in the configuration must be at least SUNW.oracle_server:8. Use the clresourcetype show command to display the version.

Before you can replicate data with Oracle Data Guard, you must be familiar with the Oracle Data Guard documentation. For information about installing and configuring the Oracle Data Guard software and its latest patches, see the Oracle Data Guard documentation.

Note - During data replication, data from a primary cluster is copied to a backup, or standby cluster. The standby cluster can be located at a site that is geographically separated from the primary cluster. The distance between the primary and standby clusters depends on the distance that your data replication product supports.

The example procedures in this chapter show how to configure Oracle Data Guard to replicate data between a primary and a standby database.
