The sessions

1st session: Logical Replication in the Disaster Recovery environment with Oracle GoldenGate
Hervé Schweitzer, Chief Technology Officer (CTO) and Principal Consultant

GoldenGate is an Oracle product which allows the replication of database applications (logical replication). However, the related databases must be consistent, at anytime. Otherwise the replication stops. Nowadays more and more companies have disaster recovery data centers and thus want to protect everything, including databases. Oracle Data Guard is usually used for the replication of Oracle environments in a Data Center (physical replication). But what happens when the replicated databases (standby) intentionally or unintentionally gets active? And is it possible to automate the GoldenGate replication in the DR Data Center too? This presentation provides an insight into these questions and proposes possible solutions.

2nd session: Dbvisit Replicate – logical replication made easy
Franck Pachot, Technology Leader and Senior Consultant   (presentation in French)

Clemens Bleile, Senior Consultant   (presentations in German)

Logical replication brings multiple concerns in a feasibility study: are datatypes compatible? Are there some conflict rules to set-up? What rate of redo can be processed? The best way to answer is to try. Dbvisit comes with a setup wizard which makes it possible to configure and run a replication on 30 minutes, what  is perfect for a PoC. Let’s do it live, from setup to running, and test common cases of conflict resolution, table re-synchronization, etc.

3rd session: Attunity Replicate – High-Performance Replication of Oracle Data to SQL Server

David Barbarin, Senior Consultant  & Vincent Matthey, Consultant   (presentation in French)
Stéphane Haby, Delivery Manager and Senior Consultant   (presentation in German)

The replication between two different databases can be very complex. Attunity replicate is a powerfully simple data replication software. This tool is easy to configure and replace the need for complex and costly custom development projects. Through different scenarios, we will test all possibilities of the replication between Oracle and SQL Server such as different datatypes, DDL and DML commands.
