What is Heartbeat in Oracle ?

Posted by FatDBA on August 27, 2012

The heartbeat functionality performs heartbeat checks towards HTTP-based network nodes on behalf of a plug-in. When a heartbeat fails, the plug-in is set to state INACTIVE. The heartbeat functionality will continue trying to connect to the node and, when a positive answer is received, the plug-in re-enters the ACTIVE state.

Is a part of Oracle Net 8/Net networking suite to provide connectivity.

@This is what i found while exploring alert.log file of one of my database.
