When starting, the CHARON-AXP software checks the available number of host CPU cores. Currently, this check is based on the maximum number of AXP CPUs that can be emulated, not on the number of the actually configured AXP CPUs. Therefore the number of host CPU cores recommended for the maximum number of emulated CPUs - as shown in the right column of the table above - must be available. If the available number of host CPU cores is below this number, CHARON-AXP will issue a warning message even if the requirements for the configured number of AXP CPUs are fulfilled. The CHARON-AXP software will work despite this warning if the requirements for the configured number of AXP CPUs are fulfilled.

Note

Hyperthreading must be switched off completely. Disable hyperthreading in the BIOS settings of the physical host or, for a VMware virtual machine, edit the virtual machine properties, select the Resources tab then select Advanced CPU. Set the Hyperthreaded Core Sharing mode to None.

Host system preparation

Info

The automatic installation of updates must be disabled.  Updates to the CHARON host must be done only in specific service maintenance periods established by the system administrator. Before applying new updates one must shutdown the operating system running on CHARON and stop all the running CHARON instances and services.

If a network-wide license (red dongle or software license) is going to be used, do the following:

...

  1. Login as the superuser ("root") on the host system. Because Sentinel HASP runtime relies on 32-bit compatibility libraries to run on Linux, the 32-bit compatibility libraries must be installed before continuing. If the emulator host has access to a package repository, either local or remote, use the following command:

    # yum install glibc.i686


    Note

    Sometimes it is not possible to use an online repository for the installation of 32-bit glibc package. In this case the following procedure should be followed:

    1. If you have a Linux distributibe CD-ROM, insert it into CD-ROM drive

    1.1. If auto-mount is not enabled, mount the CD-ROM. Example:

    # mount /dev/sr0 /mnt

    2. If you have an ISO image of the distribution CD, you can mount it using a loopback device:

    # mount /path/to/ISO-image.iso /mnt -o loop

    3. Switch to the directory containing the packages. This directory depends on your Linux distribution. Example:

    # cd /mnt/Packages/

    4. Locate the target "glibc.i686" package:

    # ls -la glibc-*i686.rpm

    5. Install the "glibc.i686" and the packages it depends on. Example:

    # rpm -i glibc-2.17-157.el7.i686.rpm nss-softokn-freebl-3.16.2.3-14.4.el7.i686.rpm

    6. If the above command reports additional unsatisfied dependencies, add the corresponding packages to the above command line.

    7. Umount the CD-ROM or ISO file if necessary:

    # umount /mnt



  2. Create a directory for the CHARON-AXP distribution and copy the TAR.GZ files there. Set this directory as the default with a "cd" command as shown in the following example:

    # mkdir /charon_dist
    # cp /temp/charon-axp-4.7-17101.68704.fc20.tar.gz /charon_dist
    # cd /charon_dist
