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

root344610 13:06:32 ?0:00 /bin/sh /etc/init.d/init.crsd run

root 1693756220 16:34:24 pts/50:00 grep crs

正常的crs进程应该有多个

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.
