Preparing the Customization File to Overwrite the sysctl Parameters

Use these instructions in this situation:

  • You want to allow the DPK setup script to change the sysctl settings on your system.

  • You want to specify sysctl values that are equal to or greater than the values for the parameters in the generated psft_unix_system.yaml file.

Note:

Review the requirements in Understanding PeopleSoft Environment Customizations before preparing the customization file.

  1. Locate the psft_unix_system.yaml file, which was installed by the deployment, in BASE_DIR/dpk/puppet/production/data.

  2. If necessary, create a psft_customizations.yaml using a standard editing tool, such as vi on Linux, and save it in the same location as the generated psft_unix_system.yaml file.

    If this is the first entry in the psft_customizations.yaml file, ensure that there are three dashes (---) on the first line of the file. Do not indent the dashes.

  3. Copy the setup_sysctl: true scalar parameter from the psft_unix_system.yaml file and paste it into the psft_customizations.yaml file.

    Do not change the parameter; it must be set to “true”. Retain the indentation as given in the delivered YAML file.

  4. Copy the entire sysctl: collection type parameter (comprised of several lines) from the psft_unix_system.yaml file and paste it into the psft_customizations.yaml file.

    Retain the indentation as given in the delivered YAML file.

setup_sysctl: true
sysctl:
    kernel.msgmnb:                65538
    kernel.msgmni:                1024
    kernel.msgmax:                65536
    kernel.shmmax:                68719476736
    kernel.shmall:                4294967296
    kernel.core_uses_pid:         1
    net.ipv4.tcp_keepalive_time:  90
    net.ipv4.tcp_timestamps:      1
    net.ipv4.tcp_window_scaling:  1
    net.ipv4.ip_local_port_range: '10000 65500'

  5. Change the values of the sysctl parameters in psft_customizations.yaml as needed, but the values must be equal to or greater than those in the generated psft_unix_system.yaml file.

  6. Save the file.

  7. Continue with the steps in Completing the Customized Deployment.
