Boost Block-level Replication with GoldenGate's TDM Technology for 100% Business Continuity
Abstract : Recent natural disasters and government regulations have created a new demand for business continuity solutions. Many vendors have offered a variety of technologies for disaster recovery that focus on recovering data after a disaster— i.e. physical disruptions— but not necessarily enabling companies to prevent an interruption to their business when a logical disruption such as a human error occurs. To have continuous operations for critical business applications, companies need solutions that can handle interruptions caused by physical and logical failures.
This white paper provides guidelines for selecting a solution for business continuity of mission critical applications. It describes the two leading business continuity technologies: block level data replication and Transactional Data Management (TDM); and compares how they handle different scenarios of failures and interruptions. The paper also evaluates how they complement each other in creating a solid and complete business continuity solution that enables not only disaster recovery, but also high availability (HA) of mission critical systems.
