Each model of CHARON-VAX has a symbolic link defined to point to the corresponding CHARON executable (see the table below). If the PATH is correctly defined, you can start a virtual machine by specifying the link followed by the configuration file. This is described further.

Running CHARON-VAX emulators

...

The next stage can be either installation of a new VAX/VMS system using a distributive distribution media provided by HP or data transfer from some existing VAX system. These possibilities will be discussed in details in the next chapters.

...

To exit from the CHARON-VAX emulator use the following methods:

ConfigurationHow to exit
No change to the template configuration file (not recommended)Kill the console from where CHARON runs (CTRL-C for example) or kill the CHARON process

Enable "F6" button in configuration file to trigger exit from CHARON:

#----------------------------------------------------------------------------

# Uncomment to allow 'F6' to terminate the running emulator.

#----------------------------------------------------------------------------

set OPA0 stop_on = F6

Press the "F6" key


(warning) Please note that before stopping CHARON-VAX, a clean shutdown of the operating system running on the virtual machine has to be performed.

Running as system service (daemon)

...

  1. Copy the sample script "/opt/charon/bin/charon.service" ( "/opt/charon/bin/charon" for Red Hat  Linux 6.x) to the "/usr/lib/systemd/system/" directory (or to your home directory for Red Hat Enterprise Linux 6.x).

    Example:

    Red Hat Linux 6.x$ cp /opt/charon/bin/charon /my_services/mv3k6_serviceRed Hat Linux 8x, 7.x and CentOS 8x, 7.x$


    $

    chmod 755 /my_services/mv3k6_service

    cp /opt/charon/bin/charon.service /usr/lib/systemd/system/mv3k6.service
    $ chmod 755 /usr/lib/systemd/system/mv3k6.service


  2. Edit the renamed file to replace sample values of the following parameters.

    Example:

    Red Hat Linux 6.x

    exec="/opt/charon/bin/mv3k6"
    prog="my_mv3k6"
    config="/my_services/mv3k6-service.cfg"

    Red Hat Linux 8.x, 7.x and CentOS 8.x, 7.x


    ExecStart=/opt/charon/bin/mv3k6 -d /my_services/mv3k6-service.cfg
    WorkingDirectory=/my_services(warning)

      "my_mv3k6" is a service name in the example above            
  3. Create and edit the configuration file ("/my_services/mv3k6-service.cfg" in the examples above) the way it was described before and make sure the following pre-requisites are met:

    • OPA0 must be configured as a virtual port or physical console, not as an operator console.

      Example:

      load virtual_serial_line OPA0 port=10003
      #load operator_console OPA0


    • Use only absolute paths to log, toy clock, nvram files and all the other data such as disk images, etc. The names of the references files must be unique.

      Example:

      ...

      set session log="/my_services/my_mv3k6.log"
      set toy container="/my_services/my_mv3k6.dat"

      load RQDX3/RQDX3 DUA
      set DUA container[0]="/my_services/mv3k6_daemon_boot_disk.vdisk"
      ...


    • Make sure the same physical devices are not used by other CHARON-VAX daemons and the OPA0 console port number is unique across the CHARON server.

Once configuration file is ready, execute the following commands (based on the examples above) to install and start CHARON-VAX as a daemon:

...

#

...

systemctl enable mv3k6.service
# systemctl start mv3k6.service

...

titleRed Hat Linux 7.x and CentOS 7.x

If you update the /usr/lib/systemd/system/

...

<my virtual

...

machine>.service file, the following command must be executed in order to take changes into account:

# systemctl daemon-reload

Warning

Note that a certain delay may appear in finding network licenses by Sentinel Run-time on CHARON-VAX host system startup. If the CHARON-VAX service is starting automatically at host system startup, it may report a "License not found" error and exit.

This problem can be avoided by specifying the "license_key_lookup_retry" parameter in the following way:

set session license_key_lookup_retry = "N [, T]"

where:

  • N = Number of retries looking for the license key (or keys)
  • T = Time between retries in seconds. If not specified, 60 seconds is used

Example:

set session license_key_lookup_retry = 5

In this example, if the license key is not found during initial scan, CHARON-VAX will do 5 more attempts waiting 60 seconds between them.

See General Settings section for more details.

...

To stop a CHARON-VAX daemon, use the following commands.

Example:

...

#

...

systemctl stop mv3k6

(warning) Please note that before stopping a CHARONCharon-VAX service, a clean shutdown of the operating system running on the virtual machine emulator has to be performed. Stopping the emulator when the guest is still running should be the last resort when all attempts to stop the guest have failed.

Removing

...

Charon-VAX service

To remove a CHARONCharon-VAX daemon use the following commands.

Example:

...

#

...

systemctl disable mv3k6.service
# rm -f /usr/lib/systemd/system/mv3k6.service

...

(warning) Please note that before removing a CHARONCharon-VAX service, a clean shutdown of the operating system running on the virtual machine has to be performed and the service has to be stopped.
