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.

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

If I increase maxuproc to the higher number, what would be ramifications?

limits.conf
LIMITS.CONF(5) Linux-PAM Manual LIMITS.CONF(5)NAME
limits.conf - configuration file for the pam_limits module
DESCRIPTION
The syntax of the lines is as follows:
<domain> <type> <item> <value>
The fields listed above should be filled as follows:
<domain>
o a username
o a groupname, with @group syntax. This should not be confused with netgroups.
o the wildcard *, for default entry.
o the wildcard %, for maxlogins limit only, can also be used with %group syntax.
NOTE: group and wildcard limits are not applied to the root user. To set a limit for the root user, this field must contain the literal
username root.
<type>
hard
for enforcing hard resource limits. These limits are set by the superuser and enforced by the Kernel. The user cannot raise his
requirement of system resources above such values.
soft
for enforcing soft resource limits. These limits are ones that the user can move up or down within the permitted range by any
pre-existing hard limits. The values specified with this token can be thought of as default values, for normal system usage.
-
for enforcing both soft and hard resource limits together.
Note, if you specify a type of '-' but neglect to supply the item and value fields then the module will never enforce any limits on
the specified user/group etc. .
<item>
core
limits the core file size (KB)
data
maximum data size (KB)
fsize
maximum filesize (KB)
memlock
maximum locked-in-memory address space (KB)
nofile
maximum number of open files
rss
maximum resident set size (KB) (Ignored in Linux 2.4.30 and higher)
stack
maximum stack size (KB)
cpu
maximum CPU time (minutes)
nproc
maximum number of processes
as
address space limit (KB)
maxlogins
maximum number of logins for this user except for this with uid=0
maxsyslogins
maximum number of logins on system
priority
the priority to run user process with (negative values boost process priority)
locks
maximum locked files (Linux 2.4 and higher)
sigpending
maximum number of pending signals (Linux 2.6 and higher)
msqqueue
maximum memory used by POSIX message queues (bytes) (Linux 2.6 and higher)
nice
maximum nice priority allowed to raise to (Linux 2.6.12 and higher) values: [-20,19]
rtprio
maximum realtime priority allowed for non-privileged processes (Linux 2.6.12 and higher)
chroot
the directory to chroot the user to
All items support the values -1, unlimited or infinity indicating no limit, except for priority and nice.
If a hard limit or soft limit of a resource is set to a valid value, but outside of the supported range of the local system, the system may
reject the new limit or unexpected behavior may occur. If the control value required is used, the module will reject the login if a limit
could not be set.
In general, individual limits have priority over group limits, so if you impose no limits for admin group, but one of the members in this
group have a limits line, the user will have its limits set according to this line.
Also, please note that all limit settings are set per login. They are not global, nor are they permanent; existing only for the duration of
the session.
In the limits configuration file, the '#' character introduces a comment - after which the rest of the line is ignored.
The pam_limits module does report configuration problems found in its configuration file and errors via syslog(3).
EXAMPLES
These are some example lines which might be specified in /etc/security/limits.conf.
* soft core 0
root hard core 100000
* hard rss 10000
@student hard nproc 20
@faculty soft nproc 20
@faculty hard nproc 50
ftp hard nproc 0
@student - maxlogins 4
