四、RebootTime参数
注意这个RebootTime参数，也很重要，缺省情况下为3s。
Default 3 seconds -the amount of time allowed for a node to complete a reboot
after the CSS daemon has been evicted.

五、心跳参数的调整
1) 10.2.0.2 to 11.1.0.7版本的修改方法
a) Shut down CRS on all but one node. For exact steps use note 309542.1
b) Execute crsctl as root to modify the misscount:
$CRS_HOME/bin/crsctl set css misscount <n> #### where <n> is the maximum private network latency in seconds
$CRS_HOME/bin/crsctl set css reboottime <r> [-force] #### (<r> is seconds)
$CRS_HOME/bin/crsctl set css disktimeout <d> [-force] #### (<d> is seconds)
c) Reboot the node where adjustment was made
d) Start all other nodes which was shutdown in step 1
e) Execute crsctl as root to confirm the change:
$CRS_HOME/bin/crsctl get css misscount
$CRS_HOME/bin/crsctl get css reboottime
$CRS_HOME/bin/crsctl get css disktimeout
2) 11gR2的修改方法
With 11gR2, these settings can be changed online without taking any node down:
a) Execute crsctl as root to modify the misscount:
$CRS_HOME/bin/crsctl set css misscount <n> #### where <n> is the maximum private network latency in seconds
$CRS_HOME/bin/crsctl set css reboottime <r> [-force] #### (<r> is seconds)
$CRS_HOME/bin/crsctl set css disktimeout <d> [-force] #### (<d> is seconds)
b) Execute crsctl as root to confirm the change:
$CRS_HOME/bin/crsctl get css misscount
$CRS_HOME/bin/crsctl get css reboottime
$CRS_HOME/bin/crsctl get css disktimeout
