Introduction to Heartbeats

A heartbeat in Geographic Edition is a container for a collection of heartbeat plug-ins. A heartbeat has a name and one property that you can tune, Query_interval. The Query_interval property specifies the delay between heartbeat status requests.

The heartbeat plug-in facilitates the actual physical monitoring activity. The plug-in is defined by a required query command or query library, an optional requester and responder agent, a type, and a Plugin_properties string.

The Geographic Edition product provides the following default plug-ins:

A default heartbeat that uses the default heartbeat plug-ins is created every time you run geops create or geops join without specifying a custom heartbeat. The name of the default heartbeat is hb_localclustername~remoteclustername. For more information about the geops command, refer to the geops(1M) man page.

You can create custom heartbeat plug-ins and associate them with existing default heartbeats or with new custom heartbeats.

Note - Custom heartbeats are provided for special circumstances and require careful configuration. Consult your Oracle specialist for assistance if your system requires the use of custom heartbeats.

If you create a custom heartbeat, you must add at least one plug-in to prevent the partnership from remaining in degraded mode.
