Application Workload Suitability for Global Data Services

Learn how to assess if your application architecture and workload are compatible with Oracle Global Data Services (GDS).

Global Data Services (GDS) is best for replication-aware application workloads; it is designed to work in replicated environments. Applications that are suitable for GDS adoption possess any of the following characteristics:

• The application can separate its work into read-only, read-mostly, and read-write services to use Oracle Active Data Guard or Oracle GoldenGate replicas. GDS does not distinguish between read-only, read-write, and read-mostly transactions. The application connectivity has to be updated to separate read-only or read-mostly services from read-write services, and the GDS administrator can configure the global services on appropriate databases. For example, a reporting application can function directly with a read-only service at an Oracle Active Data Guard standby database.
• Administrators should be aware of and avoid or resolve multi-master update conflicts to take advantage of Oracle GoldenGate replicas. For example, an internet directory application with built-in conflict resolution enables the read-write workload to be distributed across multiple databases, each open read-write and synchronized using Oracle GoldenGate multi-master replication.
• Ideally, the application is tolerant of replication lag. For example, a web-based package tracking application that allows customers to track the status of their shipments using a read-only replica, where the replica does not lag the source transactional system by more than 10 seconds.
