Ah no, we tested running a plsql loop inserting one row per second in node
1, reboot node 2, node 1 insert will hang until QFS reconfigures the new
Master which takes around 40 seconds.
We did same test using a unix loop,
while true
do
date >> txt
sleep 1
done
this hangs too when the node where it is NOT running reboots, around 40 to
50 seconds as well
Thanks
