The Interconnects Page

You can use the Oracle Enterprise Manager Interconnects page to monitor the Oracle Clusterware environment. The Interconnects page shows the public and private interfaces on the cluster and the load contributed by database instances on the interconnect, including:

  • Overall throughput across the private interconnect

  • Notification if a database instance is using public interface due to misconfiguration

  • Throughput and errors (if any) on the interconnect

  • Throughput contributed by individual instances on the interconnect

All of this information is also available as collections that have a historic view, which is useful with cluster cache coherency, such as when diagnosing problems related to cluster wait events. You can access the Interconnects page by clicking the Interconnect tab on the Cluster Database home page or clicking the Interconnect Alerts link under Diagnostic Findings on the Oracle RAC database home page.
