General Description

Note

Important information for software upgrades:

Charon-HPA version 2.0 and higher is incompatible with licences of earlier versions. Earlier product versions are incompatible with licenses for Charon-HPA 2.0 and higher. Software licenses may have to be newly created from a fingerprint file during an upgrade from versions before Charon-HPA 1.10.


A Charon emulator product will not run without a valid license. This license can be provided on a USB hardware dongle (a Sentinel HASP key) or as a software license bound to the hardware of the host system or the network license server. A loss or defect of a license will cause the emulator to stop.

...

In some emulator products it is possible to configure the number of retries and the waiting time between them by adding parameters to the emulator configuration file. Please refer to the product documentation for the details regarding the relevant parameters: license_retry_period and license_retry_count parameters (obsolete starting with version 1.10)

2. At regular intervals during the runtime of the emulator (the default license check period of 1 hour can be changed by Stromasys using the appropriate license parameters):

Excerpt

A software license is a "virtual" key with functionality very similar to a HASP network-enabled hardware dongle.

A software license does not require any special hardware but it still requires installation of the Sentinel runtime environment. 

Note

To avoid unexpected problems, do not use any Sentinel runtime software that was not provided by Stromasys without being advised to do so by your Stromasys representative.


Note

Software licenses are best suited for stable environments, because their correct function depends on certain characteristics of the host system. Changing any of these characteristics will invalidate the license.

  • If the Charon host runs on real hardware, software licenses are by default tightly bound to the hardware for which they were issued. If major hardware characteristics of the system are changed, the license will be disabled.
  • If the Charon host runs in a virtual environment (e.g., VMware), software licenses are normally bound to the virtual machine ID and a set of additional characteristics of the virtual machine. If any of these parameters are changed, the license will be disabled.

For a more detailed description of the restrictions, please refer to Software Licensing restrictions or contact your Stromasys representative.


Warning

Software licenses are very sensitive to even small changes on the host system. Therefore, it is especially important to provide for a backup license that will ensure continued operation should there be a problem with the software license. See Handling Multiple License Keys and Product Licenses for details.
