How to recreate oraInventory using Oracle Universal Installer (OUI)

I come across the missing oraInventory issue and I have recreated the inventory using Oracle Universal installer. In case inventory got corrupted, you can use the same steps.

1. Make sure you set the ORACLE_HOME variable
$ export ORACLE_HOME=/oracle/product/11203

2. Update the $ORACLE_HOME/oraInst.loc file to point to the inventory or wherever you want to keep the inventory.

Forex:- cat $ORACLE_HOME/oraInst.loc
inventory_loc=/oracle/oraInventory
inst_group=dba

3. Run below OUI command to register ORACLE_HOME

$cd $ORACLE_HOME/oui/bin
$ ./runInstaller -silent -invPtrLoc $ORACLE_HOME/oraInst.loc -attachHome ORACLE_HOME="/oracle/product/11203" ORACLE_HOME_NAME="OraDb11g_home1"

In case of RAC environment, pls use below syntax

$./runInstaller -silent -attachHome oracle_home="<oracle_home_location>"
"cluster_nodes={<node1, node2>}" local_node="<node_name>"

4. You can verify the inventory created or not using below command
$ORACLE_HOME/OPatch/opatch lsinventory -invPtrLoc $ORACLE_HOME/oraInst.loc

Deleting Oracle Home from Central Inventory

$./runInstaller -silent -detachHome -invPtrLoc $ORACLE_HOME/oraInst.loc 
ORACLE_HOME="<Oracle_Home_Location>"
