xfnts_monitor_stop Method

Because the xfnts_monitor_start method uses scds_pmf_start() to start the monitor daemon under the PMF, xfnts_monitor_stop uses scds_pmf_stop()to stop the monitor daemon.

The xfnts_monitor_stop() method calls the mon_stop method, which is defined in the xfnts.c file, as follows:

scds_syslog_debug(DBG_LEVEL_HIGH,
      "Calling scds_pmf_stop method");

   err = scds_pmf_stop(scds_handle, SCDS_PMF_TYPE_MON,
       SCDS_PMF_SINGLE_INSTANCE, SIGKILL,
       scds_get_rs_monitor_stop_timeout(scds_handle));

   if (err != SCHA_ERR_NOERR) {
      scds_syslog(LOG_ERR,
          "Failed to stop fault monitor.");
      return (1);
   }

   scds_syslog(LOG_INFO,
       "Stopped the fault monitor.");

   return (SCHA_ERR_NOERR); /* Successfully stopped monitor */
}

Note the following points about the call in svc_mon_stop() to the scds_pmf_stop() function:

• The SCDS_PMF_TYPE_MON argument identifies the program to stop as a fault monitor. This method can also stop a data service or some other type of application.

• The SCDS_PMF_SINGLE_INSTANCE argument identifies this as a single-instance resource.

• The SIGKILL argument identifies the signal to use to stop the resource instance. If this signal fails to stop the instance, scds_pmf_stop() returns with a timeout error. See the scds_pmf_stop(3HA) man page for details.

• The timeout value is that of the Monitor_stop_timeout property of the resource.
