Primary and Backup License Server

General Information

Charon-SSP for BYOL licenses support a backup license server to ensure service continuity should the primary backup server become temporarily unavailable. Backup licenses are typically limited to a certain number of emulator runtime hours.

The example below shows the output of such a license:

# /opt/license-server/license_
-bash: /opt/license-server/license_: No such file or directory
[root@ip-172-31-40-62 Kits]# /opt/license-server/license_viewer 
<<License Viewer>> Current license:

K_TYPE=COUNTDOWN
K_EXPIRED=100
K_CUSTOMER=Stromasys/Testing
K_PLATFORM=amazon.aws
K_R_DATE=1593308906
K_INTERVAL=60

P_CODE=test
P_MAJV=4
P_MINV=2
P_CPU_NUM=4
P_MAX_MEM=512MB

PRODEND

Note the parameters K_TYPE=COUNTDOWN and K_EXPIRED=100. They indicate that this is a backup license with 100 hours of emulator runtime.

Backup License Server Operation

Should the primary license server become unavailable, the emulator tries to connect to the backup license server. If this succeeds, the emulator continues to run without interruption. If no connection to a valid license can be established within 2 hours, the emulator will stop.

Please note: If you do not have a valid backup license and the primary license server is unavailable for more than 2 hours, make sure to shut down the Solaris guest operating system cleanly before the end of the grace period. Failure to do so may cause data loss or corruption.

If the primary license server becomes available again after the emulator has switched to the backup server, the emulator will automatically switch back to the primary server to avoid unnecessary depletion of the backup license runtime hours.

Log Files

Log files provide important information about the operation of the license server and the Charon-SSP software. In case of problems, this is the first place to check.
