RGM 将调用 Update 方法以通知正在运行的资源其属性已更改。唯一可为 xfnts 数据服务更改的属性与故障监视器有关。因此,只要更新了属性,xfnts_update 方法就将调用 scds_pmf_restart_fm() 以重新启动故障监视器。
/* check if the Fault monitor is already running and if so stop * and restart it. The second parameter to scds_pmf_restart_fm() * uniquely identifies the instance of the fault monitor that needs * to be restarted. */ scds_syslog(LOG_INFO, "Restarting the fault monitor."); result = scds_pmf_restart_fm(scds_handle, 0); if (result != SCHA_ERR_NOERR) { scds_syslog(LOG_ERR, "Failed to restart fault monitor."); /* Free up all the memory allocated by scds_initialize */ scds_close(&scds_handle); return (1); } scds_syslog(LOG_INFO, "Completed successfully.");
如果故障监视器有多个实例,则 scds_pmf_restart_fm() 的第二个参数将唯一标识要被重新启动的故障监视器实例。示例中的值 0 用于指明故障监视器只有一个实例。
