In this article, I will show you how to recreate oracle central inventory in Real Application Clusters. This is not an usual routine work for DBAs. It should be used when your inventory is corrupted. For example, you may encounter by executing opatch command.

We assume that you set Oracle Home properly. Therefore, in this situation, you should recreate your inventory.
Firstly, let’s get our Oracle Homes from our central inventory file. In Linux systems, it is generally pointed to by “/etc/oraInst.loc”

We have Grid Home and Oracle Home. Before starting recreation, we must copy original inventory folder from all nodes.

oracle@orcldb01:~$ mv /u01/app/oraInventory /u01/app/oraInventory.orig oracle@orcldb02:~$ mv /u01/app/oraInventory /u01/app/oraInventory.orig |
Go to OUI bin directory and run below commands from first node.

Verify the central inventory location in all the nodes to make sure the inventory was created.
