Oracle database high availability can be affected by planned and unplanned system outages. Today we’ll share two tips on ways to reduce impact of unplanned system outages:
We’re in BIG trouble if a power outage spans a continent. Since that scenario is unlikely, a data replication solution that replicates to servers in different regions provides a better approach.
TIP: Consider a high-performance data replication solution that replicates data asynchronously. Dell offers SharePlex, which only replicates application changes to the database – called Change Data Capture. The bandwidth requirements are less and there are no limitations on physical distance between the source server and the target server.
TIP: To avoid unplanned outage or lag due to a planned reporting need, consider a solution that creates a secondary instance of transactional data. SharePlex can replicate data to offload reporting from the production environment, easing the strain.
While DBAs can’t predict for a brownout, blackout or other disastrous scenario this summer, they certainly can plan for the worst. Learn how in our complimentary white paper, “Ensuring High Availability for Critical Systems and Applications.” You’ll discover how to deliver on availability SLAs through planned and unplanned outages.
