watt.art.clusteredPollingNotification.keepAliveInterval
This parameter is not supported with Integration Server 9.0 and higher. Specifies the frequency, in milliseconds, with which a secondary instance of a clustered polling notification will check to see if an executing instance is still alive. If you do not set the parameter, the secondary instance of the polling notification will change to the default maxLockDuration value of 180000 for the shared cache.
