How to attach oracle home to central inventory.

In order to register oracle home in orainventory , first of all we need to check the location of inventory file.

$cat /etc/oraInst.loc

#Oracle Installer Location File Location
inst_group=oinstall
inventory_loc=/u01/app/oracle/oraInventory

We have to go under inventory location and verify that oracle home is existing or not. Sometime our inventory file is corrupt. No worry we will re-register using below steps.

In R12.2.5:
➨ Verify Inventory Against Filesystem …

ERROR:   $FMW_Home/Oracle_EBS-app1 is not registered in the inventory

        
Corrective Action: Provide the location of a valid inventory file. If you believe the inventory is valid,
 
you may want to attach the fs2/FMW_Home/Oracle_EBS-app1.


Run ./opatch lsinventory -all to check if you ORACLE_HOME is defined.
 

If not :
 
cd $FMW_HOME/Oracle_EBS-app1/oui/bin
 
Simply execute the attachHome.sh as below.
 
 
$sh attachHome.sh
 
 
You can just check the attachHome.sh. Make sure OHOME is correct.

/dev/null 2>&1
 
./runInstaller -attachhome ORACLE_HOME=$OHOME ORACLE_HOME_NAME=$OHOMENAME $*
 
cd $CUR_DIR

cd $ORACLE_HOME/oui/bin
 
./runInstaller -silent -invPtrLoc /etc/oraInst.loc -attachHome ORACLE_HOME=< Enter ORACLE_HOME path >” ORACLE_HOME_NAME=”<Oracle_Home_name>”
