How to change file size limit on JFS2 and user file size limit on AIX 6
Check the user file size limit
bash-4.4# lsuser -a fsize root
root fsize=2097151
bash-4.4#
bash-4.4# 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) unlimited
virtual memory (kbytes, -v) unlimited
bash-4.4#
bash-4.4# ulimit -f 104857500
bash-4.4#
bash-4.4# ulimit -a
core file size (blocks, -c) 1048575
data seg size (kbytes, -d) 131072
file size (blocks, -f) 104857500

lsuser: Not a recognized flag: h
Usage: lsuser [-R load_module] [ -c | -C | -f ] [ -a attr attr ... ] { "ALL" | user1,user2 ... }
bash-4.4#
bash-4.4# vi /etc/security/limits
bash-4.4#
bash-4.4# cat /etc/security/limits
*
* Sizes are in multiples of 512 byte blocks, CPU time is in seconds
*
* fsize - soft file size in blocks
* core - soft core file size in blocks
* cpu - soft per process CPU time limit in seconds
* data - soft data segment size in blocks
* stack - soft stack segment size in blocks
* rss - soft real memory usage in blocks
* nofiles - soft file descriptor limit
* fsize_hard - hard file size in blocks
* core_hard - hard core file size in blocks
* cpu_hard - hard per process CPU time limit in seconds
* data_hard - hard data segment size in blocks
* stack_hard - hard stack segment size in blocks
* rss_hard - hard real memory usage in blocks
* nofiles_hard - hard file descriptor limit
*
* The following table contains the default hard values if the
* hard values are not explicitly defined:
*
* Attribute Value
* ========== ============
* fsize_hard set to fsize
* cpu_hard set to cpu
* core_hard -1
* data_hard -1
* stack_hard 8388608
* rss_hard -1
* nofiles_hard -1
*
* NOTE: A value of -1 implies "unlimited"
