Oracle Database: Updating Grid / Oracle Inventory Manually

In this small blog, I will tell you how to update the inventory file with node names manually.

This is useful in many cases
1.  Inventory does not have node names
2. RAC Node addition / deletion - automatic update does not happen
3. During Installation - inventory does not have node names


Case 1
Update Inventory RAC Node - Add Node names
(To be run as grid installation owner)
$ /opt/oracle/product/180/grid/oui/bin/runInstaller -silent -ignoreSysPrereqs -updateNodeList ORACLE_HOME=/opt/oracle/product/180/grid "CLUSTER_NODES={Node1,Node2}" CRS=true LOCAL_NODE=Node1

This will update the inventory on all cluster nodes (2 in this case)

Case 2
Update only on one node in case of cluster installation
(To be run as grid installation owner)
$ /opt/oracle/product/180/grid/oui/bin/runInstaller -updateNodeList -noClusterEnabled ORACLE_HOME=/opt/oracle/product/180/grid "CLUSTER_NODES={Node1,Node2}" CRS=true  LOCAL_NODE=Node2
