Oracle GDS extends the familiar RAC-Style connect-time and run-time load balancing, service failover and management capabilities – so far applicable only to a single database, to a set of replicated databases, be it within or across data centers. With a newly created concept called Global Service, Oracle GDS framework extends the notion of a database Service to a set of replicas running on a combination of Single Instance, Oracle RAC, Oracle Engineered systems, Active Data Guard and Oracle GoldenGate.
I’ve compiled a detailed cookbook that gives a walk through of the deployment and configuration of Global Data Services (GDS) for Oracle GoldenGate based replicated environments. The cookbook covers:
- Installation of Global Service Managers
- Creation of GDS catalog
- GDS Setup
- Configuration of global services for the following GDS features: Inter-database global service failover, Connect-time and Run-time load balancing, and Locality based workload routing
Here is the link to the cookbook: http://www.oracle.com/technetwork/database-features/database-ee/gds-with-ogg-cookbook-4004663.pdf . I strongly encourage you to try it out in your lab.
