Symptoms

Unable to set SUID on the oracle binary.

The file oracle binary has the -rwxr-x--x permission which is incorrect.  The SUID is not set.
Initially, "ls -lrt oracle" shows
-rwxr-x--x 1 grid oinstall 209914561 May 12 2017 oracle

Issuing "chmod 6751 oracle" should change the permission to -rwsr-s--x permission.
 chmod 6751 oracle

 However, even after issuing "chmod 6751 oracle", the permission is still at -rwxr-x--x
-rwxr-x--x 1 grid oinstall 209914561 May 12 2017 oracle
