Re: Doubt about timeout between nodes of cluster

Hello Waldirio

    >> the time to the first machine detect the second machine powered off is very big (between 1 and 2 min),

   How are you measuring this time? Are you checking alert log or are you using DB connections to check it?

   Can you also send crsd.log?
   Further, refer $CRS_HOME/bin/racgvip and there are few parameters such as check interval, restart attempts etc controlling behavior of VIP failover too. Not sure, they are applicable when machine is rebooted since heartbeat will fail before vip check..
