10g rac下status经常有unknow的解决办法

先禁用crs服务，后启用crs服务
（相当于从新启动系统，因为crs是随系统自动启动的），需要在两台节点上都执行；
具体步骤：
节点1：
1、[root@rac1 ~]# /etc/init.d/init.crs stop
2、[root@rac1 ~]# su - oracle
  [oracle@rac1 ~]$ crs_stat -t
3、[oracle@rac1 ~]$ exit
   [root@rac1 ~]# /etc/init.d/init.crs start
4、[root@rac1 ~]# su - oracle
  [oracle@rac1 ~]$ crs_stat -t
节点2：
1、[root@rac2 ~]# /etc/init.d/init.crs stop
2、[root@rac2 ~]# su - oracle
   [oracle@rac2 ~]$ crs_stat -t
3、[root@rac2 ~]# /etc/init.d/init.crs start
4、[root@rac2 ~]# su - oracle
   [oracle@rac2 ~]$ crs_stat -t

方法二：可以使用crs_stop -f先强制停止服务，在启动服务（在一台节点上运行即可）；
具体步骤：

总结：在rac环境中如果使用crs_stop -all去停rac服务时，很有可能会出现crs中的一些服务的状态是UNKNOWN，这时我们可以采用两种方法去重新启动crs服务：

1：转换到root用户下用/etc/init.d/init.crs stop先禁用crs，然后再用/etc/init.d/init.crs start去启用crs，启用crs后会自动启动crs的一系列服务，注意此种方法需要在两台节点上都执行；

2：是用crs_stop -f  参数把crs中状态是UNKNOWN的服务关掉，然后再用crs_start -f （加一个-f的参数）启动所有的服务就可以。参考：http://www.rachelp.nl/index_kb.php?menu=articles&actie=show&id=31

要分别在两个节点上执行；

在启动的过程中最好检测着crs、ASM和数据库的日志：

crs日志：
[oracle@rac1 ~]$ tail -f /u01/app/oracle/product/10.2.0/crs_1/log/rac1/alertrac1.log
[oracle@rac2 ~]$ tail -f /u01/app/oracle/product/10.2.0/crs_1/log/rac2/alertrac2.log

ASM日志：
[oracle@rac1 ~]$ tail -f /u01/app/oracle/admin/+ASM/bdump/alert_+ASM1.log 
[oracle@rac2 ~]$ tail -f /u01/app/oracle/admin/+ASM/bdump/alert_+ASM2.log
数据库日志：
[oracle@rac1 ~]$ tail -f /u01/app/oracle/admin/ora9i/bdump/alert_ora9i1.log
[oracle@rac2 ~]$ tail -f /u01/app/oracle/admin/ora9i/bdump/alert_ora9i2.log
