Before installing BMC Atrium Single Sign-On, review the following requirements:

Limitation

You cannot deploy BMC Atrium Single Sign-On on a Network File System (NFS) system.

Access and permissions

  • If you are anonrootruntime user of the BMC Atrium Single Sign-On web container instance, you must be able to write to your own home directory.
  • (Microsoft Windows) You must have administrator privileges.
  • (UNIX) You can be any user. However, root privileges are required to set up auto-startup of the services.
  • (LINUX and Oracle Solaris) The $TMP directory must have execute permissions for running the BMC Atrium Single Sign-On installer. You can assign the execute permissions by removing the noexec attribute from the /tmp line in the /etc/fstab file. For example,

    UUID=0aef28b9-3d11-4ab4-a0d4-d53d7b4d3aa4 /tmp                    ext4    defaults,noexec        1 2

    Remove the noexec attribute from the line and save the file.

    UUID=0aef28b9-3d11-4ab4-a0d4-d53d7b4d3aa4 /tmp                    ext4    defaults        1 2

    For more information see,Installation failure due to insufficient execute permissions.

Supported platforms for BMC Atrium Single Sign-On agents

Atrium Single Sign-On supports Atrium Single Sign-On agents running on the following operating systems versions or later versions.

Operating Systems - Best performance

  • Windows Server 2008, 2012
  • Solaris 10
  • Red Hat Enterprise Linux 6

Other Operating Systems

  • Windows Server 2003
  • Red Hat Enterprise Linux 5.5
  • HP-UX 11iv2
  • Novell SUSE Linux 10 

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.
