Solution

Step 1. Check the oraInst.loc file
cat /etc/oraInst.loc
inventory_loc=/app/oracle/product/11.2.0.4/oraInst.loc
inst_group=dba
Check the inventory is exist in the location and in file entries in particular sequence

Step 2. If first step is ok, Then you need to register the Oracle Home in the inventory

# cd $ORACLE_HOME/oui/bin
# ./attachHome.sh
or

# cd $ORACLE_HOME/oui/bin
#./runInstaller -silent -attachHome -invPtrLoc /app/oracle/product/11.2.0.4/oraInst.loc ORACLE_HOME=$ORACLE_HOME ORACLE_HOME_NAME=ORAHOME11Gr24
