Data Guard SQL Apply: Back to the Future
Overview In Oracle9i Database, Data Guard introduced a new type of standby technology called SQL Apply, which maintains a Logical standby database (a transactional copy of the primary database) in addition to Data Guard's existing Physical standby capability. Since its introduction, Logical Standby databases have been deployed in production at many sites worldwide augmenting customers' Disaster Recovery strategies and providing users with more access to the standby data while removing the overhead of running reports and queries on the production database. This paper provides a quick review of the Data Guard architecture, how some customers are using SQL Apply today in production and what's coming in Oracle Database 10g to improve the Data Guard SQL Apply technology.
