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):
...
- Hardware dongles require the Sentinel HASP run-time (driver) installation before the dongle can be connected to and used by the system.
- Hardware dongles (with the exception of , apart from HL-MAX dongles) , are equipped with a battery and a clock, which makes them independent of the host clock. To keep the battery charged, the dongle should occasionally be The battery is not rechargeable. However, the dongle can use the power provided by the host system while it is plugged in. By doing this, the depletion of the battery can be slowed down. Check the dongle at regular intervals if it is not permanently connected to a system even if it is not currently needed. If the battery becomes completely depleted, the dongle will be permanently unusable and must be replaced. See also: How long does the license USB dongle battery last upon a full charge.
Software License
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.
Please 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.
- 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.
- 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.
