Increase max open files hard limit without reboot

On Solaris 11, trying to increase max open files for a non-root user using projects.

User is ebspers and max open files set in projects :

ebspers@dspriap317:~$ projects -l user.ebspers

user.ebsper

projid : 101

       comment: ""

       users : ebspers

       groups : (none)

       attribs: process.max-file-descriptor=(basic,65536,deny)

               

Although 65536 is requested, only 65535 is allowed :

ebspers@dspriap317:~$ ulimit -Hn

65535

ebspers@dspriap317:~$ ulimit -Sn

65535

How can I increase the hard limit without rebooting the local zone or even the global zone? Can a system wide hard limit be set without rebooting and not use rlim_fd_cur in /etc/system.

Thanks

Richard
