PMF Functions

These functions encapsulate the PMF functionality. The DSDL model for monitoring through PMF creates and uses implicit tag values for pmfadm(1M). The PMF facility also uses implicit values for the Restart_interval, Retry_count and action_script (the -t, -n and -a options to pmfadm(1M)). Most importantly, the DSDL ties the process death history, as discovered by PMF, into the application failure history as detected by the fault monitor to compute the restart or failover decision.

This section contains the following functions.

• scds_pmf_get_status – determine if the specified instance is being monitored under PMF control.

• scds_pmf_restart_fm – restarts the fault monitor using PMF.

• scds_pmf_signal – send the specified signal to a process tree running under PMF control.

• scds_pmf_start – execute a specified program (including a fault monitor) under PMF control.

• scds_pmf_stop – terminate a process running under PMF control.

• scds_stop_monitoring — stop monitoring a process running under PMF control.
