Thanks for the reply Javier but it does not help me.
I did find information avout the hearbeat interval and the heartbeat retries.
I can tell you that by qrmutil, my heartbeat interval is set to 5 and heartbeat retries is set to 2.
But, when I boot up my cluster, I can see this :
INFO - Instance myinstance status is Down. The process will check every 20 seconds for 15 more times while the instance completes its startup...
It's those values I need to play with as my production cluster host more than 100 different databases and after a crash, 20 seconds, 15 times is barely enough.
I've been searching to find these values but t no avail so far.
I will keep looking in the doc but a little help would be appreciated.
Thanks
William
