Oracle RAC Database Failover

Oracle RAC Database Failover

You can use Oracle Real Application Cluster (RAC) to specify a connection to an Oracle service that is enabled with load balancing and high availability. Oracle RAC distributes the workload among all available nodes in the cluster. If a node fails, the workload of the unavailable node fails over to an available node. Use Oracle RAC load-balanced connections in a fail-safe environment to ensure a database connection is available even when one or more RAC nodes fail.
The following operations in the PowerCenter Repository Service are resilient to the database failover in Oracle RAC setup:
  • ExecuteQuery
  • ObjectExport
  • ObjectImport
  • PurgeVersion
  • RollbackDeployment
You cannot perform any administrator operations with Oracle RAC database failover for Informatica domain and Model Repository Service.
