• Is it possible not to kill the primary ASE but go for a failover or make the standby ASE function as an active ASE?
• Can FM be configured to wait for some time before taking any actions?
• The following FM configuration parameters are set to default values:
  
        ha/syb/hb_fm_timeout   3 sec 
        ha/syb/hb_hb_timeout   3 sec 
        ha/syb/hb_force_db_inactive   1
        ha/syb/hb_stop_db  1 
        ha/syb/hb_shutdown_sys 0
  
     and three FM configuration parameters are customized:
  
        ha/syb/failover_if_insync = 1
        ha/syb/waittime_if_unresponsive = 300
        ha/syb/failover_if_unresponsive = 1
