Zero-Downtime Database Upgrades using Oracle GoldenGate

This white paper explains how organizations can upgrade or migrate from Oracle Database 8i, through Oracle Database 11g to Oracle Database 12c – 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 across the databases, manage partial or phased migrations and upgrades, conduct post upgrade/migration data verification, and implement a reliable failback strategy. Oracle GoldenGate can be used to reduce the downtime for numerous types of migrations and upgrades, including application upgrades, database upgrades, switching storage or hardware infrastructures, and even endian changes; however the focus of this paper is upgrading the database.
