用dbca创建db时发现没有rac环境下的选项(第一页没有出现选择本地还是集群安装的选择)，怀疑是crs未启动，用crs_stat命令检查
oracle@lxsfrac08 # crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.
提示不能连接crs后台进程。说明crs后台进程未启动
尝试重起crs后台进程
/etc/init.d/init.crs start
root@lxsfrac08 # /etc/init.d/init.crs start
Startup will be queued to init within 30 seconds.
提示会在30秒后启动crs,但检查进程，未发现启动的crs进程
root@lxsfrac08 # ps -ef|grep crs
root 3446 1 0 13:06:32 ? 0:00 /bin/sh /etc/init.d/init.crsd run
root 16937 5622 0 16:34:
root@lxsfrac08 #
r
正常的crs进程应该有多个
[oracle@rac2 ~]$ ps -ef|grep crs

尝试关闭crs

错误原因：
1) 在mount /ocrvote之前,看见/ocrvote无ocr和vote文件,就在mount之后又,贸然生成一个新的ocr和vote文件. CRS启动时需要检查ocr和vote文件,发现文件为空,导致无法启动.
未明确认识到: 以前建的ocr和vote文件是建在dg之上,只需要mount就能看见.无需也不能新建.
2)
将当前的css文件清空(/var/opt/oracle/scls_scr/$nodename/oracle/下当前文件
重新生成ocr和vote文件.
