【Oracle RAC Database】Oracle Grid Infrastructure 启动流程与日志

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
