Entropy level requirements

If you are installing BMC Atrium Single Sign-On on Red Hat Enterprise Linux computers, the entropy level on the server must be at least 3000. Otherwise, you might experience installation issues. If an installation or silent installation aborts suddenly, finishes veryquickly,or takes a long time to complete, the computer might be experiencing low entropy issues. To avoid these issues, perform the following tasks:

  • Verify the level of entropy in the entropy_avail file at the following location: cat /proc/sys/kernel/random/entropy_avail
  • If the level of entropy is less than 3000, run the following commands as root user or restart your computer. Running the command is the preferred option as it helps in maintaining the entropy level after installation. If your server has a low entropy level, you should configure your server to run the following commands while starting up your server.

    rngd
    yum install rng-tools
    echo 'EXTRAOPTIONS="-i -o /dev/random -r /dev/urandom -t 10 -W 2048"' >>/etc/sysconfig/rngd
    chkconfig rngd on
    service rngd restart

You must also ensure that the "rngd" process is running.

  1. What are the Supportet OS for the WebSSO? On this Page it is not clear?

  2. See System requirements and compatibility.
    This does not point to the Systems requirements of the WebSSO. That is confusing.
    1. Thanks your comment. We'll update this page with the missing information, but in the meantime, you can find the system requirements for Atrium Single Sign-On at the following location: System Requirements.
