  • 1.  Spectrum 2023.1 installation - question about ulimit -n value

    Posted 07-11-2023 15:00

    We're preparing for a Spectrum platform 2023.1 installation. The installation guide says this:

    For Linux systems, a minimum value for file descriptors is required. Review the current Installation Guide for recommended settings. This can be set by running the ulimit command: ulimit –n limitsetting

    I'm confused because I thought I was reviewing the current Installation Guide.This raises two questions:

    1) Where is the current Installation Guide, if not the location linked above?

    2) If that is the current Installation Guide and this is a typo, what is the appropriate limitsetting?

    Hi Dave,

    Specify these settings in /etc/security/limits.conf:

    For example, let's say we're installing on RHEL 7. The soft nofile setting suggested for limits.conf is 65536. Are you saying we should run the command ulimit –n 65536 ?

    GM Dave,

    After configuring limits.conf file, run this command ulimit -n this should return 65536 or more if you have set that higher.
