It is nproc in /etc/security/limits.conf or /etc/security/limits.d/*
This per-user limit is for threads (LWPs, light-weight-processes) rather than processes.
RHEL 6 ships with
Code:
rpm -qf /etc/security/limits.d/90-nproc.conf
pam-1.1.1-20.el6.x86_64
cat /etc/security/limits.d/90-nproc.conf
# Default limit for number of user's processes to prevent
# accidental fork bombs.
# See rhbz #432903 for reasoning.
* soft nproc 1024
root soft nproc unlimited
We set this to 9000 on our servers.

Hi,
I have a 10GB iSCSI LUN attached to an AIX 5.3 system. I increased the LUN to 15GB, but the system is still showing 10GB as the Total Size.
How can I get the OS to see the extra space? Do I have to reboot the system? (2 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
So... (1 Reply)
// AIX 6.1 & Power 7 server
I have maxuproc set to 16384.

What is the maximum number of maxuproc we can go for?
If I increase maxuproc to the higher number, what would be ramifications?

renice
RENICE(1) User Commands RENICE(1)NAME
renice -- alter priority of running processes
SYNOPSIS
renice [-n] priority [[-p] pid ...] [[-g] pgrp ...] [[-u] user ...]
renice -h | -v
DESCRIPTION
Renice alters the scheduling priority of one or more running processes. The following who parameters are interpreted as process ID's,
process group ID's, or user names. Renice'ing a process group causes all processes in the process group to have their scheduling priority
altered. Renice'ing a user causes all processes owned by the user to have their scheduling priority altered. By default, the processes to
be affected are specified by their process ID's.
Options supported by renice:
-n, --priority
The scheduling priority of the process, process group, or user.
-g, --pgrp
Force who parameters to be interpreted as process group ID's.
-u, --user
Force the who parameters to be interpreted as user names.
-p, --pid
Resets the who interpretation to be (the default) process ID's.
-v, --version
Print version.
-h, --help
Print help.
For example,
renice +1 987 -u daemon root -p 32
would change the priority of process ID's 987 and 32, and all processes owned by users daemon and root.
Users other than the super-user may only alter the priority of processes they own, and can only monotonically increase their ``nice value''
(for security reasons) within the range 0 to PRIO_MAX (20), unless a nice resource limit is set (Linux 2.6.12 and higher). The super-user
may alter the priority of any process and set the priority to any value in the range PRIO_MIN (-20) to PRIO_MAX. Useful priorities are: 20
(the affected processes will run only when nothing else in the system wants to), 0 (the ``base'' scheduling priority), anything negative (to
make things go very fast).
FILES
/etc/passwd to map user names to user ID's
SEE ALSO getpriority(2), setpriority(2)BUGS
Non super-users can not increase scheduling priorities of their own processes, even if they were the ones that decreased the priorities in
the first place.
The Linux kernel (at least version 2.0.0) and linux libc (at least version 5.2.18) does not agree entirely on what the specifics of the sys-
temcall interface to set nice values is. Thus causes renice to report bogus previous nice values.
HISTORY
The renice command appeared in 4.0BSD.
AVAILABILITY
The renice command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
