I have done the following to sort it but invain.

1.I have set the nofile to 65535 /etc/security/limits.conf.
2.I have increased the open files to 65535 because it cannot
be set to unlimited

Kindly provide me action plan to resolve the issue

Forget it, this line is just information does not matter.
Nevertheless, check nofiles (or the like) in "ulimit" for Oracle instance owner (the user that starts the instance).

Hello Everyone,

The warrning message is vanished by adding

'*' at the begning of each parameter or you have to add the Os user name
i-e

Or
oratest soft nproc 2047
oratest hard nproc 16384
oratest soft nofile 65536
oratest hard nofile 65536
