Hi Shakeel,

The issue is likely that the 'nofile' hard setting in the /etc/security/limits.conf for the Oracle user is lower than the number you are attempting to set to.

The Oracle installation documentation details what the limits.conf settings should be for the Oracle user. eg.

oracle soft nofile 1024
oracle hard nofile 65536
