To Increase Ulimit Values in Redhat Linux ? Redhat-LINUX Shells like bash/csh/ksh are responsible to provide the control over various system resources to the user. Otherwise, one normal user may utilize the complete system resources and system won't be available for other users. So setting the limit to users is very important and you need to be very careful before granting shell limits to linux open file limit per process them. You need to be always make sure that system is not going out its system wide limit. For an example , if the maximum system process limit is 64K and if you grated process limit to 4 users as 24K. When these all four users try to use the maximum no of process, system will run out of its limit and you will see fork errors on the system. Here we are going to see how to set the soft limit and hard limit to the users and also we will see how to increase the system limit. From ulimit man pages, Options Explanation -a All current limits are reported -b The maximum socket buffer size -c The maximum size of core files created -d The maximum size of a processâs data segment -e The maximum scheduling priority ("nice") -f The maximum size of files written by the shell and its children -i The maximum number of pending signals -l The maximum size that may be locked into memory -m The maximum reside

Open /etc/pam.d/common-session Add following line: session required pam_limits.so System-Wide Limit Set this higher than user-limit set above. Open /etc/sysctl.conf Add following: fs.file-max = 2097152 Run: sysctl -p Above will increase "total" number of files that can remain open system-wide.

This is for an my ecplise java too many open application where the current limit of 1024 is not enough. According to the posts I've found so far, I should be able to put lines into /etc/security/limits.conf like this; soft nofile 4096 hard nofile 4096 to increase the number of open files allowed for all users. But, that's not working for me, and I think the problem is not related to that file. For all users, the default limit is 1024, regardless of what is in /etc/security/limits.conf (I have been rebooting after changing that file) $ ulimit -n 1024 Now, despite the entries in /etc/security/limits.conf I can't increase that; $ ulimit -n 2048 -bash: ulimit: open files: cannot modify limit: Operation not permitted The weird part is that I can change the limit downwards, but can't change it upwards - even to go back to a number which is below the original limit; $ ulimit -n 800 $ ulimit -n 800 $ ulimit -n 900 -bash: ulimit: open files: cannot modify limit: Operation not permitted As root, I can change that limit to whatever I want, up or down. It doesn't even seem to care about the supposedly system-wide limit in /proc/sys/fs/file-m
