Zero-Time Upgrades to Oracle Database 11g Using Oracle GoldenGate
Eliminating database downtime poses a significant challenge for IT organizations that need to upgrade or migrate mission-critical database environments running Oracle Database 8i, Oracle Database 9i, or Oracle Database 10g to Oracle Database 11g. This is particularly true for applications that must provide continuous or near-continuous operations to users who increasingly expect uninterrupted availability of online services.
This white paper explains how organizations can upgrade or migrate to Oracle Database 11g -- without downtime. Using Oracle GoldenGate’s real-time data integration and replication capabilities, businesses can perform rolling upgrades, create a clone database to offload instantiation and conversions, keep transactions in sync, manage partial or phased migrations and upgrades, conduct data verification, and implement a reliable failback strategy.
