Understanding Linux Kernel Parameter Settings

The Linux operating system uses many of the same kernel parameters as Solaris, but they are managed in a slightly different way. In the Linux 2.4 kernel, IPC parameters are defined and maintained in the /proc file system, in the directory /proc/sys/kernel. They can be modified dynamically by editing the appropriate file, but for enterprise applications, you should override the default parameters at boot time. In Oracle Linux and RedHat Linux, the default parameters can be overridden at boot time by adding entries to the /etc/sysctl.conf file. Use the command ipcs -l to view the current values for IPC resource limits.
