V$CONFIGURED_INTERCONNECTS displays all the interconnects that Oracle is aware of. This view attempts to answer the question of where Oracle found the information about a specific interconnect.

Column Datatype Description



Name of the interconnect (such as eth0)



IP address of the interconnect



If the value is YES, the interface is known to the public.

If the value is NO, the interface is known to be private. Note that if the CLUSTER_INTERCONNECTS initialization parameter is also specified, then it is expected that the interconnect is private. Oracle expects cluster traffic to be run on private interconnects only.

If the value is empty, it is unknown whether the interface is public or private.

Oracle recommends that you set the interface for Oracle Real Application Clusters (Oracle RAC) communication in the Oracle Cluster Registry (OCR).



Indicates where this interface was picked up from:

  • Oracle Cluster Registry - Interface was configured in the OCR and Oracle Database found the interface in the OCR

  • Operating-system dependent software - Oracle Database automatically detects this

  • CLUSTER_INTERCONNECTS parameter - This initialization parameter was set



The ID of the container to which the data pertains. Possible values include:

  • 0: This value is used for rows containing data that pertain to the entire CDB. This value is also used for rows in non-CDBs.

  • 1: This value is used for rows containing data that pertain to only the root

  • n: Where n is the applicable container ID for the rows containing data
