It is possible for the host running the blcollect daemon to fail in such a way that information from a license server could stop flowing to License Scheduler. Platform Computing offers a method for allowing blcollect daemons to be restarted on the collector host if they die, and starting additional blcollect daemons on remote hosts if the primary collector host dies. Contact your Platform Computing account representative to learn more.
Use BLC_HEARTBEAT_FACTOR in the Parameters section of lsf.licensescheduler to enable bld to detect blcollect failure. Define the number of times that bld receives no response from a license collector daemon (blcollect) before bld resets the values for that collector to zero. Each license usage reported to bld by the collector is treated as a heartbeat. The default is 3.
Though LSF and License Scheduler are designed to failover and failback gracefully, and Platform Computing provides a tool for reconfiguring the FLEXnet options file and restarting the license server automatically on failover or failback to preserve the integrity of the License Scheduler solution.
