Cause:

Permission issue.

Solution :

-- Change the permission.

ls -lrt /u01/app/oracle/product/12.1.0.2/dbhome_1/bin/oracle

-rwsr-s--x 1 oracle oinstall 327811823 Oct 2 16:50
/u01/app/oracle/product/12.1.0.2/dbhome_2/bin/oracle

The asm disks would be owned by grid:asmadmin so if the database needs to access those disks then the oracle binaries have to be oracle:asmadmin.

--Change the group to asmadmin :-

chgrp asmadmin /u01/app/oracle/product/12.1.0.2/dbhome_1/bin/oracle
 ls -lrt  /u01/app/oracle/product/12.1.0.2/dbhome_1/bin/oracle

 -rwsr-s–x 1 oracle asmadmin 327811823 Oct 5 16:50/u01/app/oracle/product/12.1.0.2/dbhome_2/bin/oracle
