Managing Global Services

To manage GDS global services across pool databases, you can perform add/modify/start/stop/enable/disable operations and other administrative tasks with GDSCTL.

• Creating a Global Service To create a GDS global service, perform GDSCTL add service , modify the service for Oracle Real Application Clusters (Oracle RAC) instances, and start the service.
• Starting a Global Service To start a GDS global service on eligible pool databases, perform gdsctl start service with role or lag options.
• Stopping a Global Service To stop a running GDS global service on pool databases, perform GDSCTL stop service (optionally -database ).
• Enabling a Global Service To reenable a disabled global service on a database, perform GDSCTL enable service for the target pool or database.
• Disabling a Global Service To prevent a global service from starting or failing over on databases, perform GDSCTL disable service after stopping it.
• Modifying Global Service Attributes To change global service properties or where it runs in a pool, perform GDSCTL modify service .
• Deleting a Global Service To delete a global service from GDS catalog and all databases, perform stop service then remove service .
• Adding a Service to a Global Data Services Pool To create a global service on GDS pool databases, perform gdsctl add service then modify service for RAC instances.
• Global Data Services Failover Across Regions Flow To fail over GDS services across regions, perform database switchover, start secondary apps, update/flush DNS, route traffic.
• Graceful Application Switchover Database services are used to manage workloads during the planned outage properly. Services must be properly created, and the application must obtain connections from a service.
