FAQ: WALED license manager timeout
Can you explain how the license manager time-out value works?
Harpoon checks out a token from the license manager. Periodically it
must send a "heart beat" message to the license manager to let it know
that it is still using the token. Upon termination, Harpoon checks the
token back in to the license manager.
Should Harpoon not be able to send a heart beat to the license manager,
it will give a warning to the user and try one more time. If that fails,
then Harpoon will abort. Should it succeed, then execution continues.
If the license manager does not receive a heart beat from Harpoon,
within the time-out period, it will mark that token as available for use
by others. Should some one else try to check out a token and no other free
tokens are available, then this token will be used.
The time-out period used by the license manager and by Harpoon (for
controlling heart beat frequency) can be modified by the system
administrator. By default the time-out is 20 minutes. The value can range
between 1 and 30 minutes. A lower value means more network traffic as the
client and the license manager must communicate more often. A higher value
means a longer wait for a dropped session to free the key. The default is
1200 seconds and the minimum is 600 seconds.
On UNIX machines, the time-out value is set in the bin scripts area.
Edit $SHARC_HOME/bin/waled_start and search for TIMEOUT. The value is in
On Windows machines, set the environment variable WALED2_TIMOUT to the
