修改AIX系统上传文件大小限制

使用ulimit -a查看系统当前配置
# ulimit -a

core file size (blocks, -c) 1048575

data seg size (kbytes, -d) 131072

file size (blocks, -f) 1048575

max memory size (kbytes, -m) 32768

open files (-n) 2000

pipe size (512 bytes, -p) 64

stack size (kbytes, -s) 32768

cpu time (seconds, -t) unlimited

max user processes (-u) 262144

virtual memory (kbytes, -v) unlimited

编辑ulimit默认配置文件/etc/security/limits，找到如下设置：
default:

fsize = 2097151

将文件最大尺寸限制更改为无限制，如下：
default:

fsize = -1

登出用户后，重新登录，再次查看文件大小限制：
# ulimit -a

core file size (blocks, -c) 1048575

data seg size (kbytes, -d) 131072

file size (blocks, -f) unlimited

max memory size (kbytes, -m) 32768

open files (-n) 2000

pipe size (512 bytes, -p) 64

stack size (kbytes, -s) 32768

cpu time (seconds, -t) unlimited

max user processes (-u) 262144

virtual memory (kbytes, -v) unlimited

修改完成！
