The interconnect and internode communication protocols can affect Cache Fusion performance. In addition, the interconnect bandwidth, its latency, and the efficiency of the IPC protocol determine the speed with which Cache Fusion processes block transfers.
To verify the interconnect settings of the Oracle RAC database instance to which you are connected, query the V$CLUSTER_INTERCONNECTS and V$CONFIGURED_INTERCONNECTS views. For example:
Example 13-1 Verify Interconnect Settings with V$CLUSTER_INTERCONNECTS
SQL> SELECT * FROM V$CLUSTER_INTERCONNECTS; NAME IP_ADDRESS IS_PUBLIC SOURCE --------------- -------------- --- ------------------------------- eth2 10.137.20.181 NO Oracle Cluster Repository
Note:
You can query the GV$CLUSTER_INTERCONNECTS view to display the entries for all of the instances in the cluster.
Example 13-2 Verify Interconnect Settings with V$CONFIGURED_INTERCONNECTS
SQL> SELECT * FROM V$CONFIGURED_INTERCONNECTS; NAME IP_ADDRESS IS_PUBLIC SOURCE --------------- --------------- --- ------------------------------- eth2 10.137.20.181 NO Oracle Cluster Repository eth0 10.137.8.225 YES Oracle Cluster Repository
