haemd Daemon

Purpose

Observes resource variable instances that are updated by resource monitors and generates and reports events to client programs.

Syntax

haemd

Description

The haemd (event manager) daemon observes resource variable instances that are updated by resource monitors and generates and reports events to client programs.

One instance of the haemd daemon executes on every node of a cluster. The haemd daemon is under system resource controller (SRC) control.

Because the daemon is under SRC control, it cannot be started directly from the command line. It is normally started by the emsvcsctrl command. If you must start or stop the daemon directly, use the emsvcsctrl command.

When SRC creates the haemd daemon, the actual program started is haemd_HACMP. The haemd_HACMP program, after collecting information needed by the daemon, then runs the haemd program. In other words, the haemd_HACMP program is replaced by the haemd program in the process created by SRC.

For more information about the event manager daemon, see the emsvcsctrl command.
