Configuring hosts

Before installing Voice Platform, the operating system for each Voice Platform host requires specific configuration settings.

  1. Make sure the DNS and hostname return correctly:

    > hostname (returns the hostname)

    > hostname -f (returns the fully qualified hostname)

    > hostname -i (returns the IP address)

  2. Make sure the firewall is disabled.
  3. On RHEL 7, make sure you have access to all packages from the Optional channel. You can enable the Optional channel in the RHEL subscription associated with the host or enter this command on your host to include the necessary repository.

    Using the following command on RHEL requires a licensed copy of RHEL:

    > yum-config-manager --enable rhel-7-server-optional-rpms
  4. On RHEL 8, enable the build tools:
    sudo subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpm
    sudo dnf upgrade

  5. Install required libraries. You can enter these commands to install all dependencies. There is no harm entering these commands on a system with specified packages already installed.

    On Red Hat 7, install these libraries: 

    sudo yum install perl-Data-Dumper redhat-lsb-core.x86_64 glibc.x86_64 glibc.i686 libstdc++.x86_64 libstdc++.i686 openssl libaio.x86_64 libaio.i686 libnsl.i686 libuuid.i686 ncurses-libs httpd.x86_64 unzip zlib.i686 -x postfix -x mariadb-libs

    On Red Hat 8install these libraries:

    sudo dnf update
    sudo dnf install initscripts
    sudo dnf install perl-Data-Dumper glibc.i686_64 glibc.i686 libstdc++.x86_64 libstdc++.i686 openssl libaio.x86_64 libaio.i686 libnsl.x86_64 libnsl.i686 libuuid.i686 ncurses-libs httpd.x86_64 unzip zlib.x86_64 zlib.i686

    And create a symbolic link for Red Hat 8 and above:

    sudo ln -s /lib64/ld-linux-x86-64.so.2 /lib64/ld-lsb-x86-64.so.3

Permissions for data output location

Voice Platform runs under user nuance and group nuance. By default, all Nuance components output diagnostic logs, call logs, and other data under $NUANCE_DATA_DIR. This directory belongs to user/group nuance. The environment variable is set to /var/local/Nuance.

If you configure Nuance components to write to other directories outside of $NUANCE_DATA_DIR, they must allow write permission to user and group “nuance.” This restriction also applies to third-party application servers that the Management Station watches. Each application server requires write permission for the same directories to which user or group “nuance” can write.

For more information, see Filenames and location.

  • The file system must be NTFS.
  • Disable the firewall capabilities. From the Control Panel, select Windows Firewall and check Off.
  • If you are installing Nuance speech products to a drive other than the boot drive (C:), you must first enable 8.3 naming format on that drive.
