Solaris

i am trying to change the max number of files you can open under this
enviroment
Solaris , bash .
i first check the current setting by
ulimit -a
returns like this.
------------------------------------
data seg size (kbytes) unlimited
file size (blocks) unlimited
open files 256

i then run the perl script which keeps opening files.

inside this perl program or before running this perl script, i change
the setting by
ulimit -n 1024

Yet i could only open files up to 256. Seems like the setting i changed
is not in effect. Am I doing wrong or do you have to change the file
/etc/system to take effect ?

If possible , i want to avoid rebooting the system.
Thanks in advance.

I actually ran into this one before, setting different limits will have no effect since you are using perl.

The stdio(3C) manpage notes that only 255 files may be opened using fopen(), and only file descriptors 0 through 255 can be used in a stream. Since perl calls open() and then fdopen(3C) with the resulting file descriptor, perl is limited to 256 simultaneous open files.
