Oracle Linux 6.6 Goal: user jboss_app should be able to run up to 16384 processes

We increased max user processes because a user was running out of processes. Current contents of limits.conf:

#<domain> <type> <item> <value> # #* soft core 0 #* hard rss 10000 #@student hard nproc 20 #@faculty soft nproc 20 #@faculty hard nproc 50 #ftp hard nproc 0 #@student - maxlogins 4 * soft memlock 8388608 * hard memlock 8388608 * soft nofile 16384 * hard nofile 16384 * soft nproc 16384 * hard nproc 16384 # End of file

When we log in as jboss_app, and run ulimit -a, we only see 1024 processes. allowed. 

[jboss_app@tstjboss05 ~]$ ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 386260 max locked memory (kbytes, -l) 8388608 max memory size (kbytes, -m) unlimited open files (-n) 16384 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 1024 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited

What is limiting the jboss_app user to 1024 processes after the global configuration was raised to 16384?

EDIT: IN this serverfault question I found there is another file in the RHEL family, /etc/security/limits.d/90-nproc.conf, which is read when the user is accessed vi sudo. 

[root@tstjboss05 limits.d]# more 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

I edited nproc in this file and got my desired result.

Yes I tested and it worked for me too on Oracle Linux 6.9, I updated the /etc/security/limits.d/90-nproc.conf file to get the required setting for ulimit for oracle user.

In Oracle Linux 6 it is not sufficient to update /etc/security/limits.conf.
