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.

7. Replication solves important problems for RDBMS users
• Real-time local copies in case the DBMS fails
• Real-time remote copies in case the site fails
• Loading data into quickly into analytic systems
• Feeding edge applications from the Oracle mother ship
• Migrating from Oracle to:
– New Oracle versions
– Less expensive editions
– Non-Oracle DBMS

11. VMware Continuent places minimal demands on source and
target DBMS instances
• Source Oracle DBMS requirements:
– Supplemental logging
– Archive logs
– Replicator metadata stored in DBMS
– Replicator login with access to catalogs and flashback query
– local process to read REDO logs
• Target Oracle DBMS requirements:
– Replicator metadata stored in DBMS

12. Continuent logical replication applies transactions in serial
order to targets
