xfnts_stop Method

Because the xfnts_start method uses scds_pmf_start() to start the service under PMF, xfnts_stop uses scds_pmf_stop() to stop the service.

The first call in xfnts_stop is to scds_initialize(), which performs some necessary house-keeping functions (the scds_initialize() Function and the scds_initialize(3HA) man page contain more detail.

The xfnts_stop method calls the svc_stop() method, which is defined in xfnts.c as follows.

scds_syslog(LOG_ERR, "Issuing a stop request.");
   err = scds_pmf_stop(scds_handle,
       SCDS_PMF_TYPE_SVC, SCDS_PMF_SINGLE_INSTANCE, SIGTERM,
       scds_get_rs_stop_timeout(scds_handle));

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

   scds_syslog(LOG_INFO,
       "Successfully stopped HA-XFS.");
   return (SCHA_ERR_NOERR); /* Successfully stopped */

Note the following about the call in svc_stop() to the scds_pmf_stop() function.

• SCDS_PMF_TYPE_SVC parameter identifies the program to stop as a data service application—this method can also stop a fault monitor or some other type of application.

• The SCDS_PMF_SINGLE_INSTANCE parameter identifies the signal.

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

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

Before it exits, the xfnts_stop method calls scds_close() to reclaim resources allocated by scds_initialize(). See scds_initialize() Function and the scds_close(3HA) man page for details.
