The backup should be located on your root filesystem. Thus, if some
parameters fail, you can always supply the alternative, original system
file on the boot prompt. The following shows two typically entered
parameters:
* these are the defaults of Solaris < 8
set rlim_fd_max=1024
set rlim_fd_cur=64
rlim_fd_cur
这个参数定义了一个进程可以打开文件描述符的“软”限制，该数目由当前运行的SHELL
决定；ulimit –Sn，还可以通过setrlimit()函数来修改这个参数；不需要超级用户权
限；
The predicate rlim_fd_cur <= rlim_fd_max must be fulfilled.
rlim_fd_max
default 1024, recommended >=4096
这个参数决定了一个进程可以打开文件描述符的“硬”限制；如果想改变该限制，必须
有超级用户的权限；
对于大多数SERVER，不管使用TCP还是UDP进行通讯，最大描述符数是每个用户进程的最
重要的参数；文件描述符决定了同时可以连接的数目；
ulimit -Hn
You should consider a value of at least 2 * tcp_conn_req_max and you
should provide at least 2 * rlim_fd_cur. The predicate rlim_fd_cur <=
rlim_fd_max must be fulfilled.
