OS启动OHASD（Oracle High Availability Services）

init.ohasd.run被启动，该进程负责启动ohasd.bin守护进程
[root@node01 ~]# ps -ef | grep ohasd | grep -v grep
root       515     1  0 18:59 ?        00:00:00 /bin/sh /etc/init.d/init.ohasd run >/dev/null 2>&1 </dev/null
root      1779     1  1 18:59 ?        00:00:06 /u01/app/11.2.0.4/grid/bin/ohasd.bin reboot
$ORACLE_HOME/log/node01/ohasd/ohasd.log

阶段一
OHASD会启动4个代理进程：oraagent，orarootagent，cssdagent，cssdmonitor

oraagent
