Understanding the System Parameters on Linux

The generated YAML file for UNIX operating systems includes settings for certain system parameters. When you run the DPK setup script on Linux, the script overwrites existing system-level parameters that are different from the values in BASE_DIR/dpk/puppet/production/data/psft_unix_system.yaml.

It is possible to perform a deployment and make certain changes to the way that the DPK deployment handles these system parameters. Be aware, however, that the values listed in the psft_unix_system.yaml file are the minimum requirements for the DPK deployment.

Deployments by the root user

If the root user performs the entire deployment and does not want the system-level parameters to be updated by the DPK setup script, perform a customized deployment as described in the following two sections, Reviewing the sysctl Parameters and Reviewing the ulimit Parameters.

Non-root deployments

When a deployment is performed by a non-root user, the root user must first run a prereq step. If the root user does not want the system parameters to be updated by the DPK setup script, the root user should run the prereq step without the syscfg option.
