Answer

About License Manage Software(License Server)

  1. It seems that some license issue keys are not registered.
    Check the status of registered license issue keys, and register all your license issue keys included in the software products.

    Check the status.
    # /opt/nec/aur_license/bin/reg_serialkey --check
    License-Issue-Key is not registered for the license (line=3)

    When you get the above message, register the license issue key for the product and activate it.
    # /opt/nec/aur_license/bin/reg_serialkey License-Key
    # /opt/nec/aur_license/bin/reg_serialkey --check
    OK

    OK means that all of the license issue keys are registered and you can restart the license server.
    See also the section 5.3 of HPC Software License Management Guide.

  2. When SELinux is enabled on RHEL/Rocky Linux/CentOS 8.*, settings for SELinux are needed for the license server process to access the directory writing its logs.
    The settings can be performed by semanage and restorecon commands as follows.
    # semanage fcontext -a -t var_log_t "/var/opt/nec/aur_license(/.*)?"
    # restorecon -R -F -v -r /var/opt/nec/aur_license

    If semanage is not installed, you can install it by the following command line.
    # dnf install policycoreutils-python-utils

  3. The license server checks a tamper of license file.
    Use license files downloaded from the License Issuing Web System as is.

  1. It seems that the IP address can not be resolved from sv_host which is specified by License_server_host=sv_host in /opt/nec/aur_license/aur_license.conf.

  3. Log in to the License Issuing Web System, and check that Host name and Host ID are set correctly in the SDK license host information page.
    See also About License Issuing Web System/#3 about the SDK execution host.
