In order  to overcome this issue make following changes:

a.      Go to $GRID_HOME/OPatch

      [root@db12c-01 Patch]# cd $GRID_HOME/OPatch

      [root@db12c-01 OPatch]# pwd

       /u01/app/12.1.0.2/grid/OPatch

      [root@db12c-01 OPatch]# 

b.      More opatch executable to opatch.sh

mv opatch opatch.sh

c.       Create new opatch file

vi opatch

d.      Add following line in new opatch file

/u01/app/12.1.0.2/grid/OPatch/opatch.sh $@ -jre /u01/app/12.1.0.2/grid/OPatch/jre

e.     Change permission of new opatch file

      [grid@db12c-01 OPatch]# chmod 750 opatch

      [grid@db12c-01 OPatch]# ls -l opatch opatch.sh

      -rwxr-xr-- 1 grid oinstall    82 Apr 28 21:13 opatch

      -rwxr-x--- 1 grid oinstall 44345 Apr 28 20:16 opatch.sh

      [grid@db12c-01 OPatch]#

f. Run opatch lsinventory to check it worked.
