I have put code-tags around the listing, it makes te stanza-format easier to read.
The file /etc/security/limits works this way: a user will use the values of the "default"-stanza but explizit values overwrite these defaults for the specific user. Thereofre: copy the values of the oracle-user to the other user-id to change it to the same values:
The user hast to log on again to use these new values.
I know in php if you use the function filesize it will return the size of the file in bytes, but is there an easy way to get the size in MB.

ulimit -f unlimited will only affect my current shell.
How can I increase for all users, all shells ?
Thanks in advance

Hello,
I have a script that should store file size in a variable $filesize.
I don't know what is the best way to do it.
I tried
ls -lt myfile.txt | sed something >$filesize
but I don't know how to use sed to get filesize. I know that the owner of the file is root and then we have some... (6 Replies)

Morning,
Somebody can tell me in AIX 6.1 what is the different between the maxuproc (lsattr -El sys0 | grep max) and the for a user.
Example:
Oracle is limited by :
#ulimit -u
processes(per user) unlimited
But lsattr -El sys0| grep maxuproc show me :
maxuproc 16384

Hi,
what are the ideal/best/recommended ulimit settings for a root user in AIX?
I understand that it depends on our environment. But I would like to know...what are settings you guys use in your environment for best performance.
default:
fsize = 2097151
core = 2097151

I have seen two different ways for changing the ulimit for a user in aix. Which one is better?
Option 1
edit /etc/security/limits
oracle:
fsize = -1
data = -1
stack = -1
fsize_hard = -1
nofiles = -1
nofiles_hard = -1
Option 2

prlimit
PRLIMIT(1) User Commands PRLIMIT(1)NAME
prlimit - get and set process resource limits
SYNOPSIS
prlimit [options] [--resource[=limits] [--pid PID]
prlimit [options] [--resource[=limits] command [argument...]
DESCRIPTION
Given a process ID and one or more resources, prlimit tries to retrieve and/or modify the limits.
When command is given, prlimit will run this command with the given arguments.
The limits parameter is composed of a soft and a hard value, separated by a colon (:), in order to modify the existing values. If no lim-
its are given, prlimit will display the current values. If one of the values is not given, then the existing one will be used. To specify
the unlimited or infinity limit (RLIM_INFINITY), the -1 or 'unlimited' string can be passed.
Because of the nature of limits, the soft limit must be lower or equal to the high limit (also called the ceiling). To see all available
resource limits, refer to the RESOURCE OPTIONS section.
soft:hard Specify both limits.
soft: Specify only the soft limit.
:hard Specify only the hard limit.
value Specify both limits to the same value.
GENERAL OPTIONS -h, --help
Display help text and exit.
--noheadings
Do not print a header line.
-o, --output list
Define the output columns to use. If no output arrangement is specified, then a default set is used. Use --help to get a list of
all supported columns.
-p, --pid
Specify the process id; if none is given, the running process will be used.
--raw Use the raw output format.
--verbose
Verbose mode.
-V, --version
Display version information and exit.
RESOURCE OPTIONS -c, --core[=limits]
Maximum size of a core file.
-d, --data[=limits]
Maximum data size.
-e, --nice[=limits]
Maximum nice priority allowed to raise.
-f, --fsize[=limits]
Maximum file size.
-i, --sigpending[=limits]
Maximum number of pending signals.
-l, --memlock[=limits]
Maximum locked-in-memory address space.
-m, --rss[=limits]
Maximum Resident Set Size (RSS).
-n, --nofile[=limits]
Maximum number of open files.
-q, --msgqueue[=limits]
Maximum number of bytes in POSIX message queues.
-r, --rtprio[=limits]
Maximum real-time priority.
-s, --stack[=limits]
Maximum size of the stack.
-t, --cpu[=limits]
CPU time, in seconds.
-u, --nproc[=limits]
Maximum number of processes.
-v, --as[=limits]
Address space limit.
-x, --locks[=limits]
Maximum number of file locks held.
-y, --rttime[=limits]
Timeout for real-time tasks.
EXAMPLES
prlimit --pid 13134
Display limit values for all current resources.
prlimit --pid 13134 --rss --nofile=1024:4095
Display the limits of the RSS, and set the soft and hard limits for the number of open files to 1024 and 4095, respectively.
prlimit --pid 13134 --nproc=512:
Modify only the soft limit for the number of processes.
prlimit --pid $$ --nproc=unlimited
Set for the current process both the soft and ceiling values for the number of processes to unlimited.
prlimit --cpu=10 sort -u hugefile
Set both the soft and hard CPU time limit to ten seconds and run 'sort'.
