Tools not Applicable to the VE License Server

Any Sentinel/Gemalto-specific license tools provided with the emulator installation are not applicable to the VE license server configuration.

Sentinel/Gemalto-specific tools and configuration options on in Charon -SSPemulator kits:

In Charon -SSPemulator kits, the Sentinel/Gemalto-specific license tools and configuration options are available when installing the management packages for the VE-capable Charon-SSP complete emulator packages. These tools and options are in particular the following:

  • Charon-SSP:
    • HASP Viewer, HASP Updater, and HASP Manager in the Tools > HASP Tools menu of the Charon Manager
    • The Regular and Backup License parameter in the emulator license configuration section
    • The command-line tools in /opt/charon-agent/ssp-agent/utils/license

The above tools cannot be used for managing Charon-SSP VE licenses. Please ignore them if you have a VE license.

Actions that can Invalidate a VE License

...

For cloud deployments: if supported by the cloud provider, the VE license server instance can be moved to a different subnet, as long as the original instance can be moved.

It is also possible to backup and restore (to the same instance) the license server data.

However, the following actions will invalidate the license:

...

  • Copying the license server data to a different instance
  • Seriously damaging the root filesystem of the license server system
  • Re-installing the license server system
  • Copying the virtual machine on which the license server runs
  • Changing the number of CPU cores of the license server system.

...

  • Charon-PAR:
    • The command-line tools in /opt/charon/bin (including the update tool hasp_update, and the license viewer and C2V creation tool hasp_srm_view)
    • The license_id configuration parameter is not supported. To choose a specific product section, the passphrase of the section is used.

The above tools and commands cannot be used for managing VE licenses. Please ignore them if you have a VE license.

Starting and Stopping the License Server

...

  • For general VE license mode, backup licenses are typically limited to a certain number of emulator runtime hours. The backup license server is only used for failover if the primary license server fails in order not to deplete the available runtime hours unnecessarily.
  • For AutoVE mode, the two license servers act as peers between which the client database is synchronized. The total number of instances available on both servers determines the number of Charon host cloud instances that can be licensed from the license server pair. Each instance can connect to either of the two servers. However, if one of the peers fails and there are not enough available instances on the second peer, there is no backup for an instance trying to fail over to the second  peer due to failure of its primary server - and the emulators running on this instance will fail. The

...

  • license on the server designated as backup server can be a countdown license (specified number of runtime hours) or a normal license.

The example below shows the output of a time-limited license:

Please note: The output shows a 2 hour grace period. The grace period implementation changed several times. In VE versions before version 4.1.21, the grace period was 24 hours. It was shortened to two hours after the introduction of the backup license server feature in 4.1.19. Since version 1.1.12, the grace period is determined by the corresponding license parameter. If a valid license has not become available before the end of the grace period, the emulator will be stopped.

Charon-PAR Emulator Log Files

The default location for the Charon-PAR emulator log files is the directory in which the emulator was started. The name and location can be influenced via the configuration file and using a start-up parameter.

By default log file name is charon-par.<YYMMDD>-<timestamp>-<incremental number>.log.

The link charon-par.log points to the current log file.
