The purpose of this note is to describe how to change or update the private network (cluster_interconnect) information in Oracle Clusterware.
It may be necessary to change or update interface names, or subnet associated with an interface if there is a network change affecting the servers, or if the original information that was input during the installation was incorrect. It may also be the case that for some reason, the Oracle Interface Configuration Assistant ('oifcfg') did not succeed during the installation.
Please refer to Note 276434.1 for modifying public network and VIP associated information and refer to Note 1386709.1 for basics of IPv4 subnet and Oracle Clusterware.
Note: for Oracle Engineered system (Exadata) and Oracle Database Appliance (ODA), please do not make such changes following this note.
