Oracle HA, DR, data warehouse loading, and license reduction through edge apps with VMware Continuent Replication
1 like680 views
Database replication is vital enterprise technology but is dominated by inflexible, high-cost incumbents, especially in the case of Oracle. This talk introduces VMware Continuent Replication and shows how it solves database replication problems in environments from bare metal to clouds. We’ introduce exciting new Oracle replication improvements that allow users to apply VMware Continuent to Oracle HA, DR, data warehouse loading, and license reduction through edge apps. We conclude with a demo that shows just how easy it is to deploy and use VMware Continuent Replication for Oracle.
