Compared to disaster recovery solutions that are based on either disk replication or transaction replication alone, advantages of the Mirror Activator solution are:
Lower TCO
Enhanced ROI
An integrated disaster recovery solution, with the “best of both worlds”
The Mirror Activator solution provides lower TCO with:
Reduced network bandwidth requirements, because only the primary log devices need to be mirrored (primary data devices need not be mirrored)
Hardware-independence for the standby DBMS (both hardware and operating system flexibility)
The Mirror Activator solution provides enhanced and immediate ROI with:
No downtime required for standby databases (always online and available for client applications, always up-to-date)
No idle time required for standby hardware and infrastructure (always available when not used for recovery)
Mirror Activator provides an integrated disaster recovery solution with:
Standby databases protected from disk corruption (by logical, not literal, replication)
Synchronous replication, with zero data loss and guaranteed data integrity (transactional consistency)
Complete coverage for databases, as well as nondatabase systems
