The heartbeat protocol uses UDP port 694 to send a UDP message from network 1 interface to other LB-8000. Backup manager keeps listening to port 694 and waiting for the heartbeat UDP packet sent from the primary manager, through both Network 1 and serial port interface. If primary manager is working normally, it will send a UDP packet through each Network 1 and serial port periodically.

Every node writes every two secs to its block in the heartbeat system file. The block offset is equal to its global node number. So node 0 writes to the first block, node 1 to the second, etc. All the nodes also read the heartbeat sysfile every two secs. As long as the timestamp is changing, that node is deemed alive.

LB-8000 sends heartbeat signal through both Network 1 and serial port. Only when backup fails to get heartbeat signals from both interfaces will the failover happens.

Every WAPM has a heartbeat function. The heartbeat's frequency and resolution is configurable (refer to each WAPM's specifications). The heartbeat function is like a watchdog, a WAPM will communicate with its WPIM at least once every hearbeat period. If a WPIM misses two heartbeats in a row from a WAPM, then the WPIM asserts a "loss of RF communications" trouble signal to the ACP. (back)

The Linux-HA project (http://www.linux-ha.org/) offers a high availability solution commonly referred to as Linux Heartbeat. Linux Heartbeat ships as part of several Linux distributions, as well as within several embedded high availability systems. This solution can also be used for other applications besides databases servers, such as mail servers, web servers, file servers, and DNS servers. Linux Heartbeat implements a heartbeat-protocol.

The Heartbeat Award is a national scheme promoted by and managed on a local basis by local authority Environmental Health departments in partnership with various Northamptonshire County Council departments.

Don't Panic! Your baby could just be positioned in a way that the Doppler can't locate the heart beat. Try again in another part of your belly, or walk around before trying again. If you still cannot locate the heart rate, make an appointment to see your health care provider.

Heart rate does not determine whether the baby is a girl or boy. The only way to determine the sex of the baby is through a genetic amniocentesis which is usually done after the age of 35. Ultrasound is often accurate a Cindie can tell you how confident she is at identifying the accuracy of the sex.
