Yuan, For change the current and max number of file descriptors in Solaris 2.6 (in 2.7 I think is the same but I'm not sure), you need add two entries in your /etc/system file: set rlim_fd_cur=1024 set rlim_fd_max=2048 and you MUST reboot your machine in order to changes take effect. To see if everythings works, try to use the command ulimit -a before and after the modifications. Unfortanately the max number of file descriptors wouldn't be showed, just the current will (open files parameter). Hope this helps. Regards, Claudio > Hi, > > Excuse me for asking a silly question.
