File Descriptors

When using IBM MQ on a CentOS 6.6 machine I needed to increase a couple of file descriptor numbers, specifically the system file-max as well as user hard and soft limits. The article at Linux Increase The Maximum Number Of Open Files / File Descriptors (FD) was exactly what I needed. The only point it misses is that you can set the hard and soft limits for all users in the /etc/security/limits.conf file by using a * instead of a specific username.
